A Defining Moment For Synthetics


By Katherine Bui

Published October 1999 Lubricants World

Part 1

While the field is not wide open, a new ruling confirms that the definition of "synthetic" is still largely in the hands of marketers.

Synthetic. The word has become almost a proscription in the industry, especially among scientific and technical organizations, such as the Society of Automotive Engineers (SAE) and the American Petroleum Institute (API).

Ask a marketer of motor oil products formulated with hydroprocessed mineral oils, and you might get a definition that involves cost-efficiencies and consumer choices. Ask an engineer involved in manufacturing polyalphaolefins (PAOs) or esters, and composition might be the determining factor. Despite the intense debate over the origins of synthetics, an absolute definition has remained in limbo for many years, with much of the responsibility placed on base oil manufacturers and lubricant marketers.

It was only recently, in a decision by the National Advertising Division (NAD) of the Council of Better Business Bureaus, that the first basic action and ruling in the United States set a strong precedence for a broader description in the marketing of synthetics. In this first installment of a two-part story, Lubricants World takes a look at the NAD's ruling and explores the revived debate surrounding the definition of "synthetic."

The Ruling
In a ruling released April 1999, the NAD addressed complaints filed by Mobil Oil Corp. regarding the truthfulness of Castrol North America Inc.'s claim that its Syntec® provides "superior engine protection" to all other motor oils, both synthetic and conventional, and that Syntec's esters provide "unique molecular bonding." Mobil charged that the advertisements inaccurately represented that the current formulation of Syntec is synthetic. The challenge was filed based on statements Castrol made in a series of television commercials, Web site publications, package labels, and brochures.

The NAD divided its decision to address three issues raised in the complaint. Is the reformulated Syntec synthetic motor oil? Has Castrol substantiated its superiority claims? Has Syntec been degraded?

Synthetic?
The NAD determined that the evidence presented by the advertiser constitutes a reasonable basis for the claim that Castrol Syntec, as currently formulated, is a synthetic motor oil. NAD noted that Mobil markets hydroisomerized basestocks as synthetic in Europe and elsewhere. NAD noted that the action taken by the SAE to delete any reference to "synthetic" in its description of basestocks in section J354 and API's consequent removal of any mention of "synthetic" in API1509 were decisions by the industry not to restrict use of the term "synthetic" to the definition now proffered by Mobil. Further, the SAE Automotive Lubricants Reference Book, an extensively peer-reviewed publication, states base oils made through the processes used to create Shell's hydroisomerized basestock, severe cracking, and reforming processes may be marketed as "synthetic."

Superior?
Despite its prior ruling, the NAD advised that Syntec could not advertise a superior protection claim.

Degraded?
The NAD determined that though Mobil presented clear evidence that Castrol has made a major change to Syntec's formulation, it was not sufficient to demonstrate that Syntec has been "degraded."

Industry Reaction
In a statement to Lubricants World, Castrol's legal counsel said, "The NAD's decision was clearly correct. In accepting Castrol's position on the appropriate definition of synthetic basestock and concluding that Castrol Syntec is a fully synthetic oil, the NAD accepted the overwhelming evidence Castrol presented, which included the opinions of leading scientists . . .and statements from Shell, Exxon, and other industry sources. The NAD also relied on the SAE's rejection of a restrictive definition of the type advanced by Mobil. In fact, although it had the right to do so, Mobil did not attempt to appeal the NADS's decision."

Mark Sztenderowicz, a senior research engineer from Chevron Products Co.'s Base Oil Technology Team, stated his company agreed with the NAD's decision. "We feel strongly," he said, "that 'synthetic' is a fairly broad term and a number of basestocks besides PAOs fit the description. To the extent that the NAD came to a similar conclusion and was unwilling to limit 'synthetic' to a narrow definition, we agree. We further agree with what we consider to be a commonsense interpretation that consumers perceive the word 'synthetic' to mean something man-made, but not made necessarily from a particular compound or component."

The Complaint

Mobil's Position
Mobil contended that Castrol misleads consumers that Syntec is a fully synthetic motor oil despite the fact that Syntec is no longer synthetic. The challenger alleged that after years of manufacturing Syntec with PAO, Castrol replaced the PAO, which had constituted nearly 70% of the volume of the product, with hydroprocessed mineral oil in approximately December 1997. As a result of an independent laboratory test conducted by Savant Inc., Mobil maintained that samples of Syntec purchased in June and December 1997 contained 93% and 80% PAO. Other samples of Syntec, one purchased in December 1997 and four purchased in 1998, contained no PAO, and instead contained 100% mineral oil.

Furthermore, Mobil alleged that Castrol degraded Syntec by substituting hydroprocessed mineral oil for PAO to the detriment of the consumer. Even though Syntec was able to meet the minimum industry standards, Mobil contended that in no way does it prove the current Syntec is as good as it was when it was made with PAO.

Castrol's Position
Castrol defended its claim that Castrol Syntec is synthetic based on the nature of the basestocks used in the formulation (Shell's hydroisomerized basestocks). This is substantiated by the opinions of chemistry experts; authorities from Shell and Exxon; the SAE's Automotive Lubricants Reference Book; a paper by Dr. Martin Voltz, a Mobil scientist; and an independent motor oil expert. Castrol also contends that its data show the current formulation of Syntec provides more protection than the old formulation and is, in fact, superior to Mobil 1®, Mobil's synthetic oil.

In response to Mobil's contention that Castrol deceived its consumers by not informing them of the change in the formulation, the advertiser submitted a statement by Richard Kabel, a motor oil expert. Kabel asserted that motor oil manufacturers, including Mobil, regularly make changes in their formulations without disclosing these changes to consumers. He stated that the industry certification and licensing program is designed to provide motor oil manufacturers with the flexibility to modify their formulations as long as the oil continues to meet industry standards.

The Definition of "Synthetic"
The debate regarding the use of the word "synthetic" created a tumult in the early 1990s when a push by the lubricants industry urged the API and the SAE to set a standard or official definition for the material. The argument centered on the development of very high viscosity index (VHVI) base oils that some argued provided properties similar to PAOs but cost only half as much. VHVIs or hydroisomerized basestocks are created by chemically converting the molecules of a selected feedstock to a different set of molecules, predominantly through chemical rearrangement or decomposition of the structure of the feed molecules. PAOs are derived from a chemical process that combines small molecules to make larger complex molecules of a desired type.

SAE, unable to resolve the debate, stripped references to the word "synthetics" from its terminology books and guides (J357) in 1995 and 1996, respectively. The API eliminated references to "synthetic" from its Engine Oil Licensing and Certification System (API1509).

Mobil's Definition
In the complaint filed by Mobil against Castrol's Syntec, the PAO manufacturer contended true synthetics had to be formulated from small molecules subject to a chemical reaction, not built from natural petroleum.

Mobil submitted testimony from Professor J.M. Perez, a lubrication and technology expert from Pennsylvania State University, who told the NAD that true synthetics require "the formation of chemical products from simple well-defined molecules by synthesis or chemical reaction." Perez cited isomerization, reforming, hydrotreating, and hydrocracking as some of the many chemical and physical processing steps applied to petroleum to produce a variety of useful products, but said that they do not produce synthetic products. He argued that hydroisomerization does not create synthetic material because it does not create or build molecules, but merely rearranges the same molecules that were present in the original petroleum fraction.

Professor O.L. Chapman, an expert in synthetic chemistry from the University of California, also testified that synthetic materials are constructed from pure compounds that are themselves not natural and that the resulting synthetic material has well-defined properties. PAO and ester, he said, are built from pure small molecules that have already been subject to a chemical reaction, and are not built from natural petroleum.

Mobil also asserted that the definition of synthetic propounded by Castrol is contrary to the definition used by other motor oil manufacturers and the Environmental Protection Agency (EPA). Under the EPA's 40CFR435.11(x), "the term 'synthetic' material. . . means material produced by the reaction of a specific purified chemical feedstock, as opposed to the traditional base fluids such as diesel and mineral oil, which are derived from crude oil solely through physical separation processes."

The challenger also noted that Exxon, on its Web site, stated that a synthetic lubricant is a "lubricating fluid made by chemically reacting materials of a specific chemical composition to produce a compound with planned and predictable properties. . . ." Similarly, Mobil contended Chevron, Lubrizol, Mobil, Valvoline, and Quaker State all disseminated definitions of synthetic that did not include hydroisomerized oil.

The challenger argued that Castrol does not even meet the definition of synthetic oil that it disseminates on its own Web site. Castrol's definition reads, "synthetic lubricants are manufactured chemicals . . . created in the laboratory by combining molecules" and "a lubricant produced by synthesis rather than by extraction and refinement." Mobil asserted that, in fact, Syntec meets Castrol's own Web-posted definition of mineral oil: "oil that is manufactured from crude oil by a series of refinery processes."

Despite the fact that the label does not contain the claim that Syntec is a fully synthetic motor oil, Mobil contended that Castrol's television commercials, brochures, labels, Web sites have created an automatic association for consumers that any Syntec product is a synthetic oil. In response to Castrol's assertions that SAE changed its definition of synthetics to include mineral oils, Mobil asserted that SAE's legal administrator, Steven P. Daum, has stated, "SAE has neither issued an official definition of, nor adopted a Society position on, what does or does not constitute such materials. SAE does not render opinions on what products may be marketed or advertised as synthetic motor oil."

Furthermore, Mobil contested Castrol's claim that Section J357 of SAE's "Physical and Chemical Properties of Engine Oils," described the basestocks used in manufacturing motor oils, recognizes Shell's hydroisomerized basestocks as synthetic. The challenger claimed the section is a general guide to engine oil properties and that the current version does not define or even use the word "synthetic." Mobil also argued that Castrol's assertion that SAE's Automotive Lubricants Reference Book supports hydroisomerized oil as synthetic is misleading. Mobil contended the book expresses the views of the authors and not that of SAE.

Castrol's Definition
Castrol distinguished "synthetic" from "conventional" oil in its definition. Conventional oils, according to Castrol, are taken from the ground, purified, and refined without reforming through chemical reactions. Castrol described synthetic oils as made with stocks in which the molecular structure of a substance, such as wax, has been broken apart and transformed through a chemical reaction to create a new molecule that is different from naturally occurring substances.

Castrol called Nobel Laureate Roald Hoffman and Frank H.T. Rhodes, professor of chemistry at Cornell University, who defined synthetic material as "the product of an intended chemical reaction." Hoffman also defined at least one major chemical transformation (reaction) in its manufacture of processing, but a simple "physical separation, purification, or transformation (e.g., freezing or boiling) does not constitute a synthesis."

Sir John Meurig Thomas of the Royal Institute of Great Britain reached a similar conclusion, stating that although there is no net increase in the size of the molecule in hydroisomerization, this does not prevent the process from creating a synthetic substance. Furthermore, he noted the act of isomerizing a linear paraffin into a branched-chain paraffin makes the process of producing Shell's hydroisomerized basestock as much of a synthesis as the buildup of larger hydrocarbons from smaller ones.

J.G Helpinstill, who works for Exxon in basestock and finished-product research and development, stated that it is appropriate to classify as synthetic materials that are not found in the earth's naturally occurring resources in commercial quantities, but instead are made by substantive chemical modifications of other naturally occurring or physically recoverable substances.

In 1993, Castrol asserted SAE was asked to exclude hydroisomerized products from the definition of synthetic basestocks by defining synthesis as involving the buildup of larger molecules from smaller components. The SAE, according to Castrol, decided in 1995, as did the API, to revise its guidelines to eliminate any definition of synthetic. The advertiser contended Mobil's challenge before the NAD is really an effort to reopen a debate previously lost in these industry organizations. Furthermore, Castrol contended the SAE's Automotive Lubricants Reference Book states that base oils made through severe cracking and reforming processes may be marketed as synthetic.

Castrol also maintained that basestocks like shell's hydroisomerized basestock are marketed as synthetic in 37 countries, including the United States, and that Mobil's real interest is in protecting its market dominance. The advertiser argued that Mobil, through its alliance with British Petroleum, has also marketed hydroisomerized basestocks as synthetic in Europe and elsewhere.

In a private interview with Lubricants World, Castrol's legal counsel from Paul Weiss said, "As the NAD recognized, the scientific and industry consensus view is that synthetic basestocks are manufactured through an intended chemical reaction in which the molecular structure of a substance has been transformed. Synthetic basestocks are used to produce engine oils that meet high performance specifications." Furthermore, he contended the NAD's decision confirmed that the use of judiciously chosen synthetic basestocks is essential to the formulation of a fully synthetic engine oil that meets the exacting performance standards consumers have come to expect from synthetic engine oils.

He said, "The NAD recognized, therefore, that both composition and performance are important characteristics of synthetic lubricants. Castrol requires that its Syntec full-synthetic engine oils meet those exacting performance specifications and surpass the performance of conventional products."

Industry Reaction
In Lubricant World's discussions with several lubricant companies, the case raised a diversity of opinions.

An industry expert from a major oil company prefers a description of synthetic used by the Society of Tribologists and Lubrication Engineers (STLE), which defines synthetics as man-made compounds, not naturally occurring, and that combining low-molecular-weight materials via chemical reaction into higher-molecular-weight structures makes these products. The spokesperson said, "In our opinion, that responsibility [of placing the accountability of defining synthetics in the hands of manufacturers or lubricant marketers] will yield an inconsistent application of the basestock, and inconsistencies in finished-product quality will result."

He also argued that based on PAO synthetic products, the emphasis should be based on performance rather than composition. "This is not to imply," he suggested, "that the only way to achieve enhanced performance is through the use of PAO. In Europe, for example, oil is formulated on various quality tiers, where the consumer is informed about what each tier will accomplish in his automobile (extended drains, high-RPM engines, etc.). The North American lubricant market has a long way to go to develop this type of market."

Sztenderowicz, however, applies the definition in Webster's Dictionary in the chemical context. The dictionary defines synthetic to mean, "of, relating to, or produced by chemical or biochemical synthesis, especially produced artificially," with synthesis defined as "the production of substance by the union on chemical elements, groups, or simpler compounds or by the degradation of a complex compound."

Chevron Products Co. manufactures a VHVI line of unconventional base oils (UCBOs) at its Richmond base oil plant. Based on these definitions, Sztenderowicz said, "Both Chevron PAOs and UCBOs fit this description." He noted the definition clearly links synthetics to composition or origin, but not to a specific composition, origin, or manufacturing route. "We think that a basestock in which the molecules largely are altered in some way from those appearing in the raw materials might be classified as synthetic," Sztenderowicz explained. "Performance is an issue separate from whether or not the base fluid is considered synthetic. The association is based entirely upon marketing claims. In the real world, the performance of a lubricant is a function of both the base fluid and the additives which make up the product. Although most synthetic basestocks offer certain advantages relative to conventional stocks, superior performance is not guaranteed by their use."

Henkel Lubricant Technologies refers to the traditional definition described by ASTM D 4175 from the American Society for Testing and Materials. In this case, synthetic is defined as originating from the chemical synthesis of relatively pure organic compounds from one or more of a wide variety of raw materials. Henkel produces ester basestocks used in the manufacture of synthetic or synthesized lubricants, including polyolesters, diesters, and dimer acid esters. A spokesperson for the company said, "we feel the definition of synthetics should include a combination of performance and composition."

Motiva Enterprises LLC defines synthetics as "man-made, not naturally occurring." Motiva manufactures Group III base oils known as TEXHVI 3 and 4. A representative of the company said "The definition of synthetics should be based on how it is derived."

None of the independent manufacturers contacted by Lubricants World said they had heard of the case or judgment. Denny Madden of Amalie Oil Co., which buys and manufacturers finished goods using both PAOs and VHVI basestocks, said "Personally, I have always ad a strange feeling about calling one slice of crude oil synthetic when the very nature of refining is a synthesizing process. I understand that there needs to be a way of differentiating between basestock types and that more mechanical, physical, and chemical activity takes place when one makes PAOs and other so-called synthetic stocks, but all crude is synthesized to make any number of very different products, lubricating or otherwise. So, how do I feel about the subject? Confused!"

Outcome
Castrol North America Inc. has agreed to modify its superior engine protect and "unique molecular bonding" claims in advertising for its Syntec motor oils, but continues to advertise the product as a synthetic. Castrol says it is in the process of further upgrading and reformulating Syntec. Castrol's legal counsel added separately to Lubricants World, "The NAD's decision does not make any changes. Instead, it confirms a preexisting consensus reached by industry groups, experts, and scientists."

A Mobil spokesperson told Lubricants World that "Mobil is disappointed with the NAD's decision that, in its judgment, Castrol Syntec can be advertised and marketed as synthetic motor oil. Mobil filed the challenge in order to protect consumers and the integrity of fully synthetic motor oils. Mobil 1, the top-selling fully synthetic motor oil in the world, provides several important benefits not offered by conventional blended or hydroprocessed motor oils -- benefits that can significantly improve engine performance, even under extreme conditions." Mobil currently does not have any plans to appeal the ruling.

Industry experts had mixed reactions to the impact of the decision on developing an industry-accepted definition for synthetics. A Henkel spokesperson said, "If the technical societies adopt the broader definition of synthetics, it will force more performance-driven specifications in the market and the term 'synthetic' will become meaningless." One industry expert described, "The market will move in a direction that it has historically and support synthetics as they presently are defined. PAOs will continue to thrive and support the demands of niche markets that require the highest quality basestock available.

Joe Geagea, Chevron base oils products team manager, suggested, "Currently, there is no strict definition in North America of what constitutes synthetic, and we don't expect this to change. What we really think will come out of this decision is an awareness that several types of stocks, particularly some newer UCNOs, justifiably can be considered synthetic and are viable basestocks for the formulation of top-quality synthetic lubricants. In other words, the decision sends a message that 'synthetic' is not synonymous with 'PAO'".

Part 2

As reported in Part 1 of this story (October 1999 Lubricants World), the National Advertising Division (NAD) of the Council of Better Business Bureaus ruled in April 1999 that Castrol Syntec motor oil can be marketed as a synthetic. The decision followed a complaint filed by Mobil that as of December 1997, Castrol no longer used polyalphaolefins (PAOs) but hydroprocessed base oils to formulate the product. The decision is final, but the impact it might have on the lubricants industry could open the floodgates on how synthetics are marketed.

The PAO commercial market can be traced as far back as the early 1970s, when specialized products were formulated from PAOs. However, it was not until Mobil Oil commercially marketed its Mobil 1 products 25 years ago that PAOs became a major consumer-sought lubricant product.

Since that time, the PAO market has traveled a long and winding road, enjoying slow but steady growth while fending off criticisms of high cost compared to conventional oils. In the last 10 years, the PAO market took off significantly, first in Europe and then in North America, expecting as much as double-digit growth. In part, the growth might be attributed to the stricter specifications in Europe that created a market niche for synthetic and semi-synthetic products. The demand has since extended to North America and other continents.

It was the invention of the hydrockracking process in the late 1950s, followed by Chevron’s development of hydrodewaxing or hydroisomerizing in the late 1980s, that created the process for the development of the hydrorocessed market.

The 1990s brought a change to the hydrodewaxing technology, making large volumes of high-quality basestocks available at lower cost. Much of this capacity is used to produce Group II base oils. The introduction of Group III basestocks made solely through hydroprocessing in 1996 by Chevron, Petro-Canada, and a few other base oil companies created a second generation of very high viscosity index (VHVI) oils in terms of both quality and potential capacity—that is, high-performance basestocks had gone mainstream. These base oils, which cost more than the Group IIs yet less than PAOs, do not usa a solvent-refining process and some say they may have a much higher performance level than conventional oils, almost approaching that of PAOs.
Increased severity of lubricant specifications has been the driving force in both the need and availability of PAOs and VHVIs, but it is still too early to tell in which niche these types of basestocks fall in the marketplace. Nevertheless, the NAD ruling has raised several issues regarding the marketing and application of the word “synthetic” that arguably would resolve some of these discrepancies. In this second of out two-part series, Lubricants World posed the question of the market impact of the NAD decision to a sample of representatives from a variety of segments in the lubricants industry.

Impact on Individual Companies
When asked how the NAD decision might impact individual companies, the answers were as diverse as the products each company markets. Castrol, whose formulation of Syntec utilizing hydroisomerized base oils instead of PAOs initiated Mobil’s complaint, stated it is “gratified” by the outcome of the decision.

“Castrol is proud to be a major worldwide provider of synthetic formulated lubricants, and looks forward to continued participation in this exiting market,” said a company spokesperson. “Castrol is committed to upgrading its products and producing the highest quality synthetic engine oils. We will continue to explore ways to ensure that Syntec remains a leading performer in the synthetic category.”

Mark Pernik from Chevron Chemical said, “To this point, most lubricant manufacturers are taking a conservative approach to the decision and continue to use a PAO in their synthetic formulations. In fact, Mobil has already raised the quality bar by developing a new Mobil 1 Tri-Synthetic PAO formulation. For the past 5 years, Chevron Chemical has produced a new generation of PAOs that enhance performance for longer drain intervals. These products improve on important properties such as VI, oxidative stability, and volatility from traditionally available PAOs.

Joe C. Costa, manager of specialty/niche lubricants at Conoco Lubricants, said, “This decision will have a minimal impact on our company as we are poised to provide the optimum lubricants to meet our customers’ needs, regardless of the marketing definition of ‘synthetic base oil.’ Conoco has made a major decision to commit to heavily hydroprocessed/hydroisomerized basestocks. And yet, we also supply lubricants based on ‘chemically synthesized’ base oils, such as PAOs…We continue to provide a complete offering to our customers so that they always have the highest value product to meet their needs.”

Chevron, which produces both unconventional base oils (UCBOs) and PAOs, believes the impact on its market will depend on customers’ needs and preferences. Joe Geagea, manager of the Chevron Base Oils Products Team, argued, “overall, we expect significant growth in the UBCO segment at some short-term expense of the PAO segment, followed by growth of both segments in the long term.” Brent Lok, Chevron Base Oils Product Development manager, added, “In addition to the expected growth in UCBO sales, our finished-oils colleagues are looking at options for the use of UCBOs in Chevron’s synthetic product lines.”

Henkel, which produces ester basestocks used in the manufacturing of synthetic or synthesized lubricants, could see little impact on the company based on the NAD’s ruling. A Henkel spokesperson said, “Henkel’s products are performance driven and customer focused.”

Ed Newman of added, "AMSOIL has been the recognized leader in the development of synthetic motor oils, and we always strive to maintain the highest performance criteria for our products. For this reason, we do not foresee any negative impact because [our] customers tend to focus more on performance criteria rather than name tags.”

Valvoline’s official position regarding the decision was stated as follows: “Valvoline will not comment on rulings or decisions which impact our competitors. Our own product formulations are confidential for competitive reasons.”

Like many of the independent manufacturers Lubricants World surveyed, Amalie Oil Co., an independent blender and packager for motor oil companies that purchases and manufacturers finished goods using both PAOs and VHVIs, said it had not heard enough about the case to make a judgment. However, Denny Madden of Amalie described the decision as shocking and confusing for the market.

George Crow, president of Cross Oil Refining and Marketing Co., responded to the NAD decisions as follows: “Let’s start off with one very important premise, that motor oil is, after all, mainly a marketing-driven event. We are not talking [about] whether these oils meet the requirements for which they were blended; rather, we are talking about the attack on Mobil’s long-held dominance in the synthetic market. And they built this position around PAOs. If another product actually can give equal performance to PAOs, then Mobil is at a cost disadvantage. It will definitely affect Mobil, being a producer of PAOs…It will enhance the standing of the VHVI producers, which are becoming more numerous. In this case Petro-Canada, Chevron, Shell Europe, Exxon, Texaco, and soon Sun will be able to compete, economically, with Mobil. In the past, this was not the case.”

Crow continued, “Now, after saying all of this, and if Mobil is able to keep their brand image and advertising strong, they will be able to continue to maintain their number one position in synthetics. They may have to reduce their price on PAOs, or have to revert to using all or some VHVI material to economically compete. Or just not make as much money as their competitors will on the sale of a quart of synthetic product. I think this will make PAOs become more competitive with VHVIs and enhance the demand for VHVIs in the future. I think it is a good move for the industry, a good move for Castrol, and an unfortunate event for Mobil. For Cross Oil, it will not have an immediate impact at all. But down the road a bit, if we want to get into the finished-oil package business, it will allow Cross to make more money on the sale of synthetic or semi-synthetic products, assuming PAOs stay at a higher price than VHVIs.”

Impact on the Synthetic Base Oil Market
In the past 7 or 8 years, synthetics, in general, have seen increased activity. One brand that exemplifies this trend has been Castrol’s Syntec, whose market share in the last 5 years has climbed from virtually nothing to 20%. Nearly every major oil company currently has a synthetic product line. Based on this trend, the NAD decision has set a tone that may significantly impact the “synthetic” base oil market, specifically the supply and demand of PAOs and VHVIs.

A Castrol spokesperson assessed, “As the NAD’s decision reflects, synthetic engine oils formulated with high-quality hydroisomerized basestocks—like the basestock used in Castrol Syntec—clearly match the performance specifications of synthetic engine oils formulated with PAO basestocks. For that reason, such stocks have been, and will continue to be, competitive with PAO basestocks. Castrol believes that consumers will continue to benefit from that competition.”

An expert familiar with PAOs disagrees. He said, “The market is reading too much into the decision and trying to cast a broader net for other mineral oil basestocks. It is very important to note that Castrol’s claim was made for a very specific product from a very specific feedstock. Castrol argued that Shell’s XHVI from a slack wax stream is synthetic. The spokesperson indicated this is the part of the decision that has the largest potential impact. The quality of Group III products in inconsistent, and their physical properties are different from one manufacturer to the next. If these products were to be classified as synthetic, and suppliers use some of the poorer quality Group IIIs in the synthetic market, consumers will be misled and the high-margin niche that has been developed by present-day synthetics will erode.”

Costa of Conoco Lubricants suggested, “Presently, the supply and demand for PAOs as lubricant basestocks are generally in balance. Thus, a decision or ruling allowing the use of another (particularly less expensive) oil into the segment of the market now occupied by PAOs will obviously create a temporary softness in the PAO market.”

Lok of Chevron contended the jury is still out on the impact of the NAD’s decision. “Many of our customers are still studying this ruling and deciding what course of action to take. In the immediate future, high-performance Group III base oils will probably gain some volume at the expense of PAOs. But the enhanced competition can very likely expand the total size of the synthetic market, allowing for continued growth of both PAO and Group III UCBOs.” Lok said he believes the PAO market will always be a niche market because of the limited availability of PAO feedstocks.

“The availability of new fully hydroprocessed Group III base oils, whose capacities are measured in thousands of barrels per day, will allow manufacturers to specify high performance in mainstream applications,” said Lok. He further suggested, “We think that this development can further increase the already healthy growth rate of the synthetic market, to the point that both PAO and Group III UCBOs can co-exist in the market place.”
A Henkel spokesperson said, “We believe that the market would begin to differentiate products by performance rather than by a definition that may have been ompromised.”

Newman of AMSOIL suggested, “We’re concerned about the message to consumers. The NAD decision will result in increased confusion in the marketplace among consumers. Even the experts aren’t entirely in agreement on this matter. If a Group III basestock is acceptable as ‘synthetic,’ it helps all Group III products and weakens the meaning of the word ‘synthetic.’ Not all Group III lubricants are created equal.” He added, “True synthetics will continue to offer significant performance advantages, including high- and low-temperature performance under extreme conditions, oxidative stability, and lower volatility, to name a few.”

What’s Ahead?
The synthetic market faces many challenges other than those directly related to the NAD ruling. Consolidations, mergers, and acquisitions are changing the key players in the industry. Driven by demand and increasing specification hurdles, both base oil manufacturers and aftermarket formulators may have to address the performance, composition and supply of synthetics. Economics will also play an important role in driving the market.

However, these factors are all uncertain. What is certain is that “synthetics,” a component of higher performance, will remain a strong presence in the marketplace. At its current precarious state, any ruling -- whether it is through the court system or the NAD – may tip the scales in determining the outgrowth and market of synthetics, whether they are PAOs or hydroisomerized basestocks.

Superior Filtration Leads to Reduced Costs, Extended Equipment Life


SAE study proved direct correlation between particle size and engine wear.

A great deal of emphasis is placed on the importance of using of the most advanced high-quality lubricants, but superior filtration is often taken for granted. The general attitude displayed by many consumers is to use whatever is cheapest, even when they’ve invested in superior lubrication. While AMSOIL synthetic motor oils provide unbeatable protection, performance and economy, they require the assistance of filtration. Without filtration, by-products from the combustion process and abrasive materials ingested from the air will ultimately destroy an engine.

Some Contaminants Cause More Damage

The level of damage particles cause to an engine is directly related to the size of the particles. The oil stream within the engine flows between wear-sensitive surfaces that usually have clearances between 2 and 22 microns. It is contaminants in this size range that pose the greatest threat as they can slip between moving components, causing a great deal of wear.

To appreciate how small these particles are, one must first understand the measurements involved in their classification.

A micron, or micrometer (μ), is a very small unit of linear measurement. One micron is equal to one millionth of a meter, and 25 microns is equal to 0.001 inch. To better put this in perspective, consider that the diameter of a human hair is 50 - 70 microns.

Large particles are particles measuring 1/2” or larger. They pose little threat to engines because they are easily removed by the air filter.


Medium particles are particles measuring 25μ to 1/2”. While they are of greater concern than large particles because they are more difficult to remove, the threat they pose is diminished since they are still larger than many of the clearances within an engine. Their size will not allow them to enter the contact areas between many components to promote accelerated wear.


Small particles are particles measuring between 5 and 25μ. Small particles are of greatest concern because they can penetrate the clearances between wear-sensitive components and promote accelerated wear.And, because they are so small, they are difficult to remove from the oil stream.


SAE Testing

In the 1988 Correlating Lube Oil Filtration Efficiencies With Engine Wear technical paper published by the Society of Automotive Engineers (SAE), the relationship between filtration
levels and abrasive engine wear was established. Testing determined that wear was reduced by as much as 70 percent by switching from a 40μ filter to a 15μ filter. The SAE conducted tests on a heavy-duty diesel engine and an automotive gasoline engine, and both provided consistent
results.

New Technology Provides New Options

The SAE paper on filtration discusses the introduction of synthetic fibers into the oil filter market, which offer “the capability of achieving high levels of filtration without the traditional
sacrifice of dirt holding capacity and increased flow restriction.” Today, a new pinnacle has been reached with synthetic nanofiber technology and AMSOIL Ea Oil Filters. While today’s filters offer even greater performance, the message then was the same as it is now; removal of particles
measuring 2 to 25μ is the key to controlling engine wear, and there is a direct correlation between oil filter efficiency and engine wear.

Test Results

To establish a relationship between levels of filtration and engine wear rates, the SAE used a variety of oil filter types in its tests. Three glass filters and one traditional cellulose media filter were used in the diesel tests, while one cellulose, one glass and two glass/cellulose-blend filters were used in the gasoline engine tests. The micron rating of each oil filter was determined, and testing was conducted according to SAE guidelines. The Filter Particle Retention Curves chart on the next page shows the particle retention for each filter tested. The filters were tested at their 98 percent efficiency point and their single pass efficiency curves were determined by comparing
the number of particles upstream from the filter with the number of particles downstream. The Engine Wear Rates charts demonstrate the correlation between superior filtration and reduced engine wear. The filters that provided superior efficiency also provided superior engine protection.

Filter / Micron Rating Media@ 98% Efficiency / Composition

Diesel
(A)___40____Cellulose
(B)___15____Glass
(C)___8.5____Glass
(D)___7_____Glass

Gasoline
(E)___40___Cellulose
(F) __ 30___Glass/Cellulose
(G)___25___Glass/Cellulose
(H)___15___Glass





Conclusions

The SAE paper summarizes the test results with the following conclusions:

“Abrasive engine wear can be substantially reduced with an increase in filter single pass efficiency. Compared to a 40μ filter, engine wear was reduced by 50% with 30μ filtration. Likewise, wear was reduced by 70% with 15μ filtration. “Controlling the abrasive contaminants in the range of 2 to 22μ in the lube oil is necessary for controlling engine wear.
“The micron rating of a filter, as established in a single pass efficiency type test, does an excellent job in indicating the filter’s ability to remove abrasive particles in the engine lube oil
system.”

Today’s Most Advanced Filtration Product

Ea Oil Filters have been evaluated using today’s benchmark test, the ISO 4548-12 multi-pass test. AMSOIL Ea Oil Filters provide 98.7 percent efficiency at 15μ and up to 70 percent efficiency at 7μ. Competitive filters range from approximately 85 to 92 percent efficiency at 15μ.



When it comes to removing contaminants in the most critical size range (2 to 22μ), AMSOIL Ea Filters greatly outperform competitive filters.

Summary

Even with all of the advances in lubrication and engine technology, filtration is as important today as it ever was. The combustion process produces by-products that slip into the oil
stream, and external contaminants are introduced into the engine in a variety of ways. The challenge for filter manufacturers is balancing flow, efficiency and filter life. In order to stop
particles in the 2 to 22μ range, the pores in the cellulose media used in many filters are too small to allow adequate oil flow.

Only AMSOIL Ea Oil and Air Filters feature full-synthetic nanofiber technology. It is the nanofibers that allow Ea Filters to provide greater efficiency than any other filter available. Ea
Filters stop more particles, stop smaller particles and last longer than any other oil filter available for auto/light truck applications.

What's In Your Motor Oil

By Tom Schaefer

To a formulator, a motor oil is a complex blend of 10-15 ingredients carefully balanced and tested to meet the industry specifications and market claims. To a blender it can be as simple as mixing three liquids together and filling it into bottles. And to the consumer it is, for the most part, a mysterious golden fluid with confusing numbers and letters that all make the same claims about being the best product possible for your car. In reality, it is all of these things.

While some oil producers blend many individual components to make their motor oils, most oils are made by simply blending three fluids; a DI package, a VI improver, and a base oil. These fluids, however, are the complex products of extensive research and technology. Following is a brief summary of each:

DI Package

An acronym for Detergent Inhibitor package, this thick dark fluid is a concentrated cocktail containing most of the performance additives needed to formulate an oil. DI packs are generally made by additive companies, the largest of which are Lubrizol (independent), Oronite (a Chevron Texaco company), and Infineum (ExxonMobil/Shell joint venture). These companies have extensive R&D facilities with numerous engine test stands for developing and qualifying motor oil formulations against various global standards. The development and testing costs are so high that they are beyond the reach of many oil blenders and marketers, so the work is usually left to these experts to concoct the formulation and give it to their customers. Naturally the approvals (SM, CF etc.) are only valid if one follows the formula, which requires that you use their DI pack in approved base oils. Some majors develop their own proprietary additive systems and buy the components instead of the complete package.

The DI pack for an SM/CF passenger car motor oil is jam packed full of goodies as follows:

Dispersants: These are chemicals that can disperse and suspend solid particles formed in the combustion of fuel that might otherwise be deposited in your engine as sludge. Consisting mainly of polyamine chemistry, these molecules have “polar heads” that attach to acidic molecules and solids such as soot, and a hydrocarbon tail that keeps it all in suspension until removed by the filter or oil change. Think of them as pollywogs who surround a particle – the fat heads bite the particle and the tails keeps them swimming. Dispersants are the largest component in the DI pack, especially in diesel formulations where there are a lot more soot particles to deal with.

Detergents: Also polar in nature, these “organometalic” products made from organic chemicals and metals are responsible for neutralizing acids formed during the combustion process, and cleaning the engine from high temperature deposits by removing and preventing the adherence of deposit precursors. Some detergents are “overbased”, that is, forced to contain more metal atoms than they really want to, and are best at neutralizing acid by-products. Others are “neutral” detergents which are somewhat more effective at the cleaning process. The most common metal atoms used are Calcium (Ca), Magnesium (Mg), and Sodium (Na), and these are all measurable in the UOA and VOA analysis. The organic portions are usually sulfonates, phenates, and salicylates.

Friction Modifiers: Often esters or partial esters, these additives are very polar, thus attaching to metal surfaces to improve lubricity. FMs are used to improve fuel economy, as opposed to reducing wear, and are additive to the effects of lower viscosity.

Seal Conditioners: Also often esters, seal conditioners are potent additives used in small dosages and designed to keep seals pliable. These are especially important for highly paraffinic base oils such as Group IIIs or PAOs due to the tendency of these base oils to shrink and harden seals.

Zinc Dialkyldithiophosphate: Affectionately known as “ZDDP”, this miracle multi-purpose chemical and has been the chief anti-wear (AW), extreme pressure (EP), and anti-oxidant (AO) additive for decades. It is so effective and low cost that it is virtually irreplaceable, which is why it survives all efforts to remove phosphorus (P) from oils to protect the catalyst. With modern oils putting caps on the maximum P allowed, other additives are now being used to supplement this old standard, such as Molybdenum anti-wear compounds and ashless anti-oxidants. There are different types of ZDDPs including primaries, secondaries, and aryls, each with its own strengths & weaknesses, and the mix is balanced to the type of service the oil will see.

Anti-Oxidants: These sacrificial molecules react preferentially with oxygen to protect the other components from the degrading effects of oxidation. While oxygen is 21% of the air we breath, most people don’t realize that in its pure form it is so reactive it is considered a flammable gas! Even diluted in air, it is everywhere and wants to react with just about everything if conditions are right, such as high temperatures. Oxidation, the reaction with oxygen, is the main cause of oil thickening and left unchecked will lead to varnish and carbon deposits as well. With the ZDDP being reduced, supplemental AOs are more critical in modern oils and usually more than one kind is used to capitalize on the common synergistic properties they possess. The most common types are phenolics and amines.

Rust & Corrosion Inhibitors: These additives are smaller in dosage and are designed to protect iron alloys and yellow metals from corrosion induced by oxygen, acids and water. They work by attaching to metal surfaces and therefore compete with some other additives and base oils, so balance is critical.

Pour Point Depressants: These polymeric molecules interfere with the formation and growth of wax crystals from residual paraffins. They are generally not needed in full PAO and ester based oils since they contain no wax.

Anti-Foams: Often silicone products, these molecules are not soluble and work by suspending tiny micron sized droplets that prevent foam from forming or help the foam break faster.

Diluent Oil: Also called carrier oil, this component is usually mineral oil and is present at about 5-20% in the DI pack to solubilize all the additives and adjust the package to a consistent and manageable viscosity for pumping and blending.

Finished DI packages will vary in chemistry, balance, and dosage according to what kind of oil you are making. For example heavy duty diesel DIs will have more dispersants and be used at dosages up to about 15% of the finished oil. Passenger car/light truck DIs have less ZDDP and more anti-oxidants and are generally dosed at about 8-12%.

Viscosity Index Improvers

Abbreviated VIIs, these are huge polymeric molecules, often with molecular weights in the millions. Their purpose is to improve the viscosity index of the finished oil so that multi-grades can be made.

All organic liquids will thin out when heated and thicken up when cooled, but they don't all do so at the same rate. Viscosity Index is simply a scale to compare the rate of viscosity change with temperature among different fluids. A fluid that thins more upon heating (and therefore thickens more upon cooling) has a lower VI than one that thins less and thickens less. Or put another way, higher VI oils change their viscosity less when the temperature changes. This can be a good property for lubricants that are used in a wide temperature range.

The VI scale was originally established by assigning a value of "0" (zero) to the worse known base oil at the time, and "100" to the best. The theory was that all other base oils would then fall between these end points. Apparently they didn't anticipate synthetics or hydrocracked mineral oils back then.

The way VI Improvers work is that the huge molecules tend to coil up into balls when cold, thus having little effect on the oil’s flow (viscosity). When hot, however, the molecules uncoil and stretch out, thus interfering with the flow of the oil and causing an increase in viscosity (actually a reduction in thinning, but let’s not get technical). If you put these molecules into a light 5W base oil, the low temperature viscosity is little affected, i.e. remains a 5W, but the high temperature viscosity rises, giving for example a 5W-30 multi-grade. By reducing the thinning effect of heat, the Viscosity Index of the finished oil is increased.

VI Improvers are available an various chemistries and forms. Some are solids that need to be dissolved in the oil, but most are pre-dissolved in a carrier oil to give a thick, honey-like liquid that is easier to handle and faster to blend. Dosages are usually under 10% and vary with the VII chemistry, target oil grade, and base oil type.

People tend to think that the less VI Improver the better, but that depends on the type of VI Improver used. Some are much more shear stable than others, and a higher quantity of a shear stable VII may be better than a lower quantity of a non-shear stable VII. In addition to permanent viscosity loss cause by breaking (shearing) the large VII molecules, they also exhibit temporary viscosity losses under high shear, and this lowers the HTHS viscosity and improves fuel economy.

Base Oils

Constituting 80-90% of the finished motor oil, the base oil(s) play a very important role. The structure and stability of the base oils dictate the flow characteristics of the oil and the temperature range in which it can operate, as well as many other vital properties such as volatility, lubricity, and cleanliness. The two major categories of base oils are Mineral Oils and Synthetics.

Mineral oils begin with crude oil, a mixture of literally hundreds of different molecules derived from the decomposition of prehistoric plant and animal life. The lighter more volatile components of crude oil are stripped away to make gasoline and other fuels, and the heaviest components are used in asphalt and tar. It’s the middle cuts that have the right thickness or viscosity for lubricants, but first they must be cleaned up; undesirable components such as waxes, unsaturated hydrocarbons, and nitrogen and sulfur compounds must be removed. Modern processing techniques do a pretty good job of removing these undesirable components, good enough for well over 90% of the world’s lubricant applications, but they cannot remove all of the bad actors. And it’s these residual “weak links” that limit the capabilities of mineral oils, usually by triggering breakdown reactions at high temperatures or freezing up when cold. These inherent weaknesses limit the temperature range in which mineral oils can be used and shorten the useful life of the finished lubricant.

Mineral oils are further subdivided into three subgroups (Group I, Group II, Group III) that differ by the degree of processing they undergo. Higher groups have been subjected to hydrotreating or cracking to open aromatic (ringed) molecules, eliminate unstable double bonds, and remove other undesirables. This extra treating yields water-white clear liquid with higher VIs, enhanced oxidative stability, and lower volatility.

Group IIIs are a somewhat controversial class as they are derived from crude oil like Groups I & II, but their molecules have been so changed by severe processing that they are marketed as Synthetics. Most people now accept Group IIIs as synthetic, but the discussion remains heated among purists, and I’m going to duck by not taking a side here.

Synthetic base oils are manufactured by man from relatively pure and simple chemical building blocks, which are then reacted together or synthesized into new, larger molecules. The resulting synthetic basestock consists only of the preselected molecules and has no undesirable weak links that inhibit performance. This ability to preselect or design specific ideal molecules tailored for a given job, and then create those molecules and only those molecules, opens a whole new world for making superior basestocks for lubricants. In fact, the entire formulation approach is different: instead of trying to clean up a naturally occurring chemical soup to acceptable levels with a constant eye on cost, the synthetic chemist is able to focus on optimum performance in a specific application with the knowledge that he can build the necessary molecules to achieve it. And since full synthetic oils are generally a company’s premier offering, their best foot forward so to speak, the additives are often better and in higher doses as performance trumps cost.

In general, synthetic base oils offer higher oxidative and thermal stability, lower pour points, lower volatility, higher VI, higher flash points, higher lubricity, better fuel economy, and better engine cleanliness. The amount and balance of these improvements vary by synthetic type, and can be quite significant for the engine and user.

There are many types of synthetic base oils, the most common being Polyalphaolefins (PAOs), Esters, Alkylated Naphthenes (ANs), and more recently Group IIIs. These different types of synthetic base oils are often blended together (or even with mineral oils), to give the balance of properties desired. All offer improved performance, but at a higher price, which brings up the question of value - how much performance to you need, and how much should you pay for it?

For the average car owner, driving conditions are mild enough for conventional mineral oils to work satisfactorily, provided they are changed relatively frequently (3,000-5,000 miles). For those users with high performance engines, severe climates, hard driving, or utilizing long drain intervals, synthetics can offer good value and may even be required. And then there are those who so love their cars that nothing but the very best will do for their baby.

So, as you can see, modern motor oils are very simple mixtures of very complex ingredients. Choosing the right components of the right chemistry in the right dosages is a real balancing act, as each of the components have their own pluses and minuses and can interact or compete with each other. Don’t try this at home - leave it to companies you trust who have the technology, R&D, and resources to achieve the necessary balance so critical to performance.Choosing the right components of the right chemistry in the right dosages is a real balancing act, as each of the components have their own pluses and minuses and can interact or compete with each other.

Ten Myths About Synthetic Lubrication

First Published in National Oil and Lube News by Ed Newman

It's a fact of life that behavior is strongly influenced by what people believe, whether true or not. Numerous examples from history bear this out. For example, sailors were once fearful of sailing outside the sight of land lest they would fall off the edge of the world. In the early 19th century, the train was considered dangerous because it was believed that if you moved faster than 25 miles per hour, you would be travelling too fast to breathe. At a later date, the New York Times warned that electric light may cause blindness. Microwave ovens, automobiles and airplanes have had equally vociferous opponents.

Looking back, it's easy to laugh at some of the things people so firmly believed. But these people were not stupid. They were simply misinformed. In many instances they had simply drawn conclusions before all the facts were in. How easy it is to make the same mistake today. In our own time, synthetic motor oils have been the object of numerous misconceptions held by the general public. Many people, including some mechanics who ought to know better, have been misled by persistent myths that need to be addressed.

PARAMETERS OF THE DEBATE
Synthetic lubricants are fuel efficient, extended life lubricants manufactured from select basestocks and special purpose additives. In contrast to petroleum oils which are pumped from the earth and refined, synthetics are custom-designed in the laboratory, with each phase of their molecular construction programmed to produce, in effect, the ideal lubricant.

In responding to the objections most commonly raised against synthetics it is important to establish the parameters of the debate. When speaking of synthetic motor oils, this article is defending the synthetic lubricants which have been formulated to meet the performance standards set by the American Petroleum Institute (API). (The first such synthetic motor oil to meet these industry-accepted tests for defining engine oil properties and performance characteristics was AMSOIL 100% Synthetic 10W-40 in 1972.)

Many people with questions about synthetics haven't known where to turn to get correct information. Is it super oil or snake oil? Some enthusiasts will swear that synthetics are capable of raising your specialty car from the dead. On the other hand, the next fellow asserts that synthetics will send your beloved car to an early grave. Where's the truth in all this?

In an effort to set the record straight, we've assembled here ten of the more persistent myths about synthetic motor oils to see how they stack up against the facts.

Myth #1: Synthetic motor oils damage seals.

Untrue. It would be foolhardy for lubricant manufacturers to build a product that is incompatible with seals. The composition of seals presents problems that both petroleum oils and synthetics must overcome. Made from elastomers, seals are inherently difficult to standardize.

Ultimately it is the additive mix in oil that counts. Additives to control seal swell, shrinkage and hardening are required, whether it be a synthetic or petroleum product that is being produced.

Myth #2: Synthetics are too thin to stay in the engine.

Untrue. In order for a lubricant to be classified in any SAE grade (10W-30, 10W-40, etc.) it has to meet certain guidelines with regard to viscosity ("thickness").

For example, it makes no difference whether it's 10W-40 petroleum or 10W-40 synthetic, at -25 degrees centigrade (-13F) and 100 degrees centigrade (212 degrees F) the oil has to maintain a standardized viscosity or it can't be rated a 10W-40.

Myth #3: Synthetics cause cars to use more oil.

Untrue. Synthetic motor oils are intended for use in mechanically sound engines, that is, engines that don't leak. In such engines, oil consumption will actually be reduced. First, because of the lower volatility of synlubes. Second, because of the better sealing characteristics between piston rings and cylinder walls. And finally, because of the superior oxidation stability (i.e. resistance of synthetics against reacting with oxygen at high temperatures.)

Myth #4: Synthetic lubricants are not compatible with petroleum.

Untrue. The synthesized hydrocarbons, polyalphaolefins (PAO), diesters and other materials that form the base stocks of high-quality name brand synthetics are fully compatible with petroleum oils. In the old days, some companies used untested ingredients that were not compatible, causing quality synlubes to suffer a bum rap. Fortunately, those days are long gone.

Compatibility is something to keep in mind, however, whether using petroleum oils or synthetics. It is usually best to use the same oil for topping off that you have been running in the engine. That is, it is preferable to not mix your oils, even if it is Valvoline or Quaker State you are using. The reason is this: the functions of additives blended for specific characteristics can be offset when oils with different additive packages are put together. For optimal performance, it is better to use the same oil throughout.

Myth #5: Synthetic lubricants are not readily available.

Untrue. This may have been the case two decades ago when AMSOIL and Mobil 1 were the only real choices, but today nearly every major oil company has added a synthetic product to their lines. This in itself is a testament to the value synthetics offer.

Myth #6: Synthetic lubricants produce sludge.

Untrue. In point of fact, synthetic motor oils are more sludge resistant than their petroleum counterparts, resisting the effects of high temperature and oxidation. In the presence of high temperatures, two things happen. First, an oil's lighter ingredients boil off, making the oil thicker. Second, many of the complex chemicals found naturally in petroleum basestocks begin to react with each other, forming sludges, gums and varnishes. One result is a loss of fluidity at low temperatures, slowing the timely flow of oil to the engine for vital component protection. Further negative effects of thickened oil include the restriction of oil flow into critical areas, greater wear and loss of fuel economy.

Because of their higher flash points, and their ability to withstand evaporation loss and oxidation, synthetics are much more resistant to sludge development.

Two other causes of sludge -- ingested dirt and water dilution -- can be a problem in any kind of oil, whether petroleum or synthetic. These are problems with the air filtration system and the cooling system respectively, not the oil.

Myth #7: Synthetics can't be used with catalytic converters or oxygen sensors.

Untrue. There is no difference between synthetic and petroleum oils in regards to these components. Both synthetic and petroleum motor oils are similar compounds and neither is damaging to catalytic converters or oxygen sensors.

Myth#8: Synthetics void warranties.

Untrue. No major manufacturer of automobiles specifically bans the use of synthetic lubricants. In point of fact, increasing numbers of high performance cars are arriving on showroom floors with synthetic motor oils as factory fill.

New vehicle warranties are based upon the use of oils meeting specific API Service Classifications (for example, SG/CE). Synthetic lubricants which meet current API Service requirements are perfectly suited for use in any vehicle without affecting the validity of the new car warranty. In point of fact, in the twenty-five years that AMSOIL Synthetic Lubricants have been used in extended service situations, over billions of miles of actual driving, these oils have not been faulted once for voiding an automaker's warranty.

Myth #9: Synthetics last forever.

Untrue. Although some experts feel that synthetic basestocks themselves can be used forever, it is well known that eventually the additives will falter and cause the oil to require changing. Moisture, fuel dilution and acids (the by-products of combustion) tend to use up additives in an oil, allowing degradation to occur.

However, by "topping off", additives can be replenished. Through good filtration and periodic oil analysis, synthetic engine oils protect an engine for lengths of time far beyond the capability of non-synthetics.

Myth #10: Synthetics are too expensive.

Untrue. Tests and experience have proven that synthetics can greatly extend drain intervals, provide better fuel economy, reduce engine wear and enable vehicles to operate with greater reliability. All these elements combine to make synthetic engine oils more economical than conventional non-synthetics.

In Europe, synthetics have enjoyed increasing acceptance as car buyers look first to performance and long term value rather than initial price. As more sophisticated technology places greater demands on today's motor oils, we will no doubt see an increasing re-evaluation of oil buying habits in this country as well.

CONCLUSIONS
Since their inception, manufacturers of synthetic motor oils have sought to educate the public about the facts regarding synthetics, and the need for consumers to make their lubrication purchasing decisions based on quality rather than price. As was the case with microwave ovens or electric lights, a highly technological improvement must often overcome a fair amount of public skepticism and consumer inertia before it is embraced by the general population.

But the word is getting out as a growing number of motorists worldwide experience the benefits of synthetic lubrication. The wave of the future, in auto lubes, is well under way.
