In Industry Standard Four-Ball Wear Testing, Harley-Davidson's Own Genuine Motor Oil Produces a High Wear Scar vs. Twelve Other Leading Motorcycle Oil's. (complete test data is shown on this page for H-D Oil as well as 26 other popular Motorcycle Oils)

Harley-Davidson Maintains That You Use Their "Genuine" Motor Oil, yet Harley-Davidson Doesn't Make Their Own Motor Oil.

Learn The Facts About Harley-Davidson Oil in this Eye-Opening Article written by A.J. Amatuzio, President and CEO of AMSOIL INC.

"A situation my daughter, Lyn, told me about recently got me to thinking about how good it is to be able to blend our own oils and have complete control over our own product quality.

Lyn loves to ride motorcycles. She recently purchased a Harley Davidson motorcycle and took it to the local Harley shop to have our AMSOIL Motorcycle Oil installed. The mechanic took issue with her not using the oil Harley-Davidson sells, saying, "I'll use AMSOIL motor oil when AMSOIL starts making motorcycles!"

How would you answer a challenge like that? I was pleased to hear Lyn's response. She said, " I'll start using Harley Davidson motor oil when Harley starts making oil!"

Perfect! The fact is that Harley-Davidson, like so many other "brands" of oil, contract with one or more oil companies to make their lubricants. Often, the decision as to who actually makes a private labeled product is based on low bid, and like almost everything manufactured by a low bidder, short cuts are taken in order to meet the low price.

I understand that Harley Davidson has contracted with one company for a number of years to make their oil. That's good, but it still doesn't change the fact that they make motorcycles, not oil. Now consider all the private label oils out there. Every manufacturer that makes equipment with an engine has it's own name on an oil bottle. That includes all the major auto manufacturers, the makers of motorcycles, ATV's, snowmobiles, farm equipment, you name it, they all have oils. But none of these equipment manufacturers actually make an oil. They sell oil to make more money, and then they often price these oils well above the going rate for competitive lubricants because, like Harley-Davidson, they can specify or create the impression that only their oil be used in their equipment.

Now there's nothing wrong in having a goal to make money, but let's get real here. Why would anyone want to use a product manufactured down to a price rather than up to high quality standards? We have tested a number of these private label motor oils and two-cycle oils and we found that many are mediocre quality products. None of them even comes close to performing as well as AMSOIL lubricants, and that's a fact!

I'm not taking shots at Harley-Davidson. They make good motorcycles. And I understand their concern that normal automotive oils not meeting API C specs shouldn't be used in their bikes. But when they imply that AMSOIL Motorcycle Oil is not as good as their brand or I hear that one of their dealers recommended not using AMSOIL, I get a little hostile. Those kinds of statements are the very reason we introduced our motorcycle oils in the first place. And when we say use our 20W-50 motorcycle oil in V-Twin motorcycle engines, that definitely includes any Harley Davidson motorcycle.

Our Motorcycle Products Brochure, G-391, includes wear comparisons of AMSOIL Motorcycle Oils vs. other oils, including H-D "Genuine". Both our oils demonstrate superior wear protection over all other tested brands. Interestingly enough, the highest wear scar in this test turned out to be Harley-Davidson's own "Genuine" oil!

There is a good reason why AMSOIL Motorcycle Oil protects so well against wear. They are formulated with significantly higher levels of zinc and phosphorus, which when included in proper formulation with other high quality additives, provide superior wear protection at the high operating temperatures typical of motorcycles. In addition, synthetic oils inherently reduce sump temperatures so the engines actually run cooler.

The fact is, Harley Davidson would do well to have AMSOIL make their oils for them. Then they could be assured that their oil was indeed a superior product. As it is, there may be absolutely nothing wrong with their oil for use in average service, but I guarantee you as the oil temperature gets hotter, like it does when sitting in traffic on asphalt on a hot summer day, the Harley-Davidson with AMSOIL in the crankcase is going to be far better protected and run far cooler than the bike with H-D "Genuine" oil in it. There's just no two ways about it!

So, my daughter Lyn will be going back to this mechanic armed with the facts about AMSOIL Motorcycle Oils and a few facts about H-D oil. Nobody's going to tell her that her dad's oils are not the very best. She knows better, and she's on a mission to prove her point. Who knows? Knowing Lyn, she might sign up another AMSOIL Dealer in the process."

We now have the latest test results comparing the new H-D Synthetic Screamin' Eagle Syn3 to AMSOIL 20W-50 Motorcycle Oil. The most notable differences between the two products are in the 4-ball wear test.

In the 4-Ball Parameter 1 test the H-D Screamin' Eagle Syn3 leaves a wear scar of 0.40 mm and the AMSOIL 20W-50 Synthetic Motorcycle Oil leaves a wear scar of 0.35 mm.

In the more severe 4-Ball Parameter 3 test the H-D Screamin Eagle Syn3 leaves a wear scar of 0.70 mm and the AMSOIL 20W-50 Synthetic Motorcycle Oil leaves a wear scar of 0.39 mm. This data indicates that the H-D Synthetic oil leaves a wear scar 79% higher than the AMSOIL motorcycle oil.

The suggested retail price for the H-D Syn3 synthetic is $8.25 while the suggested retail price for the AMSOIL 20W-50 Motorcycle Oil is $9.25 and the AMSOIL change intervals specification is two times that of the H-D Syn3 synthetic or one-year, whichever comes first.

Why Harley Owners Choose AMSOIL

Wear Test Comparison AMSOIL vs. Harley Screamin� Eagle Syn3:

What about your Harley-Davidson Warranty?

A letter to the editor in the Summer 2007 issue of Harley-Davidson Enthusiast magazine asks, �Would I void the warranty if this lubricant is not specified in the H-D owner�s manual?�

The editor responds by saying, �SYN3 is the only synthetic motor oil that does not impact your 24-month, unlimited-mile factory warranty.�

Of course, this is untrue and would be a direct violation of the Magnuson Moss Warranty Act. The Magnuson-Moss Warranty Act, among other things, requires the manufacturer to provide oil free of charge if they specify that their oil is the only oil that can be used their vehicles.

The next issue of Enthusiast contains a letter from another reader who corrects the editor�s response from the summer issue. The letter-writer requests a correction if it was a misprint, or the paperwork necessary to obtain his free oil if it was not. The editor notes that the magazine received dozens of similar letters (including one from AMSOIL INC.Executive Vice President Dean Alexander), and Enthusiast addressed the issue in an interview with Larry Gutjahr, P&A Lubricants Category Manager at Harley-Davidson

Gutjahr quickly denounces the claim that the use of other synthetic oils will void Harley-Davidson�s warranty and explains that Harley recommends its own brand of oil because they don�t test other oils.

�No, that�s not true. We cannot and would not void a warranty for use of another brand of oil.�

P&A Lubricants Category Manager
Harley-Davidson

The recent introduction of Screamin� Eagle Synthetic Lubricant by Harley-Davidson indicates the Motor Company has finally recognized the benefits of running synthetic motorcycle oil in their air-cooled engines. After years of advising dealers and customers to avoid using synthetic oils in their bikes, it�s natural to wonder why the company is suddenly marketing one.

For the past 20 years, Harley-Davidson has claimed its petroleum-based Genuine H-D Oils is best for the �unique requirements of Harley-Davidson air-cooled V-twin engines.� However, laboratory testing has consistently revealed the Genuine H-D Oil does not provide the best protection possible for Harley-Davidson engines. In fact, Four-Ball Wear Tests show Harley-Davidson 20W-50 Motorcycle Oil leaves a wear scar over 50 percent larger than that left by AMSOIL Synthetic 20W-50 Motorcycle oil.

The Harley Davidson Screamin' Eagle 20W-50 Synthetic Motorcycle Oil leaves a wear scar of 0.70 mm while the AMSOIL 20W-50 Synthetic Motorcycle Oil leaves a wear scar of 0.39 mm. The Four-Ball Wear Test is the industry's standard test method for measuring the wear preventative characteristics of a lubricant. Placed in a bath of the test lubricant, three fixed steel balls are put into contact with a fourth ball in rotating contact at preset test conditions of 40 kg pressure @150 deg. C., 1800 RPM for 1 hour duration. Lubricant wear protection properties are measured by comparing the average wear scars on the three fixed balls. The smaller the average wear scar, the better the protection.

One of the major benefits of running a synthetic motorcycle oil is its resistance to oxidation and thermal degradation, which inhibit the formation of sludge and deposits that contribute to increased wear. In the past, Harley-Davidson has defended use of its Genuine H-D Oil by arguing that oil breakdown in extreme heat is a non-issue because extreme heat conditions are not normally faced by motorcycle engines, while the superior cold-temperature benefits of synthetics also don�t apply to Harley�s.

The fact is, engine oil in Harley-Davidson motorcycle is subject to very high temperatures. Being air-cooled, Harley-Davidson engines get especially hot while idling in traffic, commonly reaching temperatures up to 240 degrees Fahrenheit. As heat and oxidation increase, so does viscosity, adversely affecting the lubrication qualities of the oil and increase wear.

The water, soot and acid byproducts of combustion also contribute to deposit formation. Harley-Davidson has stressed the importance of regular oil changes in order to remove these contaminants. Of course, promoting regular oil changes is also a good way to promote using petroleum-based Genuine H-D Oil. High quality synthetic oils formulated with high-performance additives effectively withstand such contaminates allowing motorcyclist to safely extend drain intervals.

In support of their about-face and the introduction of synthetic oil, Harley maintains, �the Motor Company has never supported the use of synthetic products in our vehicles because there has never been any test validation completed on the numerous formulation in HD/Buell motorcycles. This product has been exclusively designed for Harley-Davidson and is the only synthetic product TESTED and CERTIFIED by Harley-Davidson engineering for use in H/D Buell motorcycles�

Although this is necessary marketing hype. Harley-Davidson V-twin air-cooled engines are not unique in their lubrication requirements and do not require a special Harley-only fluid. There is nothing about Screamin� Eagle Synthetic Motorcycle Oil that sets it apart form, or makes it better than, many other synthetic motorcycle oil formulation. Except that Harley-Davidson is marketing it and directly profiting from the sales.

According to Harley-Davidson, one of the unique benefits offered by Screamin� Eagle Synthetic Motorcycle Oil is its versatility. For the first time the company is recommending and oil that can be used in the engines, primary chain cases and transmission of most Harley-Davidson motorcycles, including Evolution XL, Evolution 1340, Twin Cam 88 and 88B, Revolution and Buell models. This feature, however, is not unique. AMSOIL 20W-50W Synthetic Motorcycle Oil may also be used in the engines. Primary chaincases and transmission of these applications, providing superior lubrication protection in each component.

How does Screamin� Eagle Synthetic Motorcycle Oil measure up to AMSOIL in wear protection? Four-Ball Wear Test results indicate that AMSOIL Synthetic Motorcycle Oil still provides the best protection possible for motorcycles. In fact, Screamin� Eagle Synthetic Motorcycle Oil leaves a wear scar nearly 80 percent larger that AMSOIL 20W-50 Synthetic motorcycle Oil.

Not only does AMSOIL Synthetic Motorcycle Oil offers greater wear protection than Screamin� Eagle Synthetic Motorcycle Oil, it also delivers greater value Suggested retail price of Screamin� Eagle is nearly $2 a quart higher than AMSOIL 20W-50 Motorcycle Oil. And because AMSOIL Synthetic Motorcycle Oil may be used for extended drain intervals, while Screamin� Eagle is recommended for standard drain intervals, AMSOIL customers realize additional savings.

Harley-Davidson claims Screamin� Eagle Synthetic Motorcycle Oil has been �exclusively designed� for use in their motorcycles, pointing to extensive bench testing and over 230,000 miles of durability testing to back it up. AMSOIL INC. has 33 years of experience providing superior lubrication protection for all brands of motorcycles, and AMSOIL Synthetic Motorcycle Oils have been tested in millions of over-the-road miles. Testimonials from countless motorcyclists further demonstrate the superiority of AMSOIL Synthetic Motorcycles Oils.

Formulated with top-of-the-line synthetic base stocks and high-temperature deposits control additives, AMSOIL Synthetic Motorcycle Oils provide superior protection and performance for motorcycles in all operating conditions. AMSOIL Motorcycle Oils effectively withstand oxidation and thermal degradation, keep wear to an absolute minimum, hold contaminants in suspension and keep engines running cool and clean.

Please note: Prior to H-D releasing a synthetic we have found that many Harley-Davidson technicians were telling customers that synthetic motor oil is "too slippery" and can cause flat spots on roller bearings because the bearings won't turn. Now that H-D has their own synthetic they don't mention that to much any more. It is both scientifically and chemically untrue.

Synthetic motor oils are no more "slippery" than petroleum motor oils. The tractive coefficient, which is the measure of the case with which a lubricant facilitates sliding, is essentially the same for both petroleum oils and synthetics. Synthetic motor oils are also used in many production and racing cars that have sophisticated roller follower technology and they have absolutely no problems whatsoever with roller bearings not turning. We have an article on this which we will include in your package, that explains this in more detail.

Harley-Davidson Engine, Transmission and Primary Chaincase Lubricant Recommendations

Harley-Davidson recommends 20W-50 Synthetic Motorcycle Oil for the engine, transmission and primary chaincase on the 1340 and 1450 cc models.

In order to be consistent with this recommendation we are also recommending the AMSOIL 20W-50 Synthetic Motorcycle Oil (product code MCV) in the engine, transmission and primary chaincase on the 1340 and 1450 cc models.

For 883cc and 1200cc Sportster motorcycles, the AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) is recommended for both the engine and transmission.

An optional alternative on 1340cc and 1450cc models is to use the AMSOIL 20W-50 Motorcycle Oil (MCV) in the engine crankcase, AMSOIL Synthetic Severe Gear 75W-90 Gear Lube (SVG) for the transmission and the AMSOIL 10W-40 Synthetic Motorcycle Oil (MCF) for the chaincase.

There is no right or wrong choice, it is simply a matter of personal preference. Some customers prefer to use the Severe Gear 75W-90 gear lube in the transmission and the 10W-40 Synthetic Motorcycle Oil in the primary chaincase while others use the 20W-50 (MCV) in all three areas and with both options customers report a noticeable performance improvement, including smoother shifting and lower engine temperatures.

The AMSOIL 20W-50 Synthetic Motorcycle oil (MCV) provides superior gear protection, meeting API GL-1 gear lube viscosity requirements for those customers that choose to use it in their transmission. The AMSOIL Severe Gear 75W-90 Gear Lube meets API GL-5 gear lube viscosity requirements and is an extreme severe duty rated transmission lubricant for those customers that choose to use the Severe Gear 75W-90.

Either choice of AMSOIL products as outlined in this notice will outperform the Harley-Davidson Syn3 oil as documented by independent ASTM laboratory testing as shown in our new White Paper: "A Study of Motorcycle Oils"

The change interval specification on the AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) is two times Harley-Davidson's recommended change intervals or one-year, whichever comes first. The AMSOIL EAoM Absolute Efficiency Motorcycle Oil Filters are specified as two times Harley Davidson's oil filter recommended change intervals or one-year, whichever comes first.

PRODUCT DESCRIPTION
AMSOIL Synthetic 20W-50 Motorcycle Oil (MCV) is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. AMSOIL MCV is the result of extensive research, and it is specially formulated to excel in all areas unique to motorcycles, including high temperatures of air-cooled engines such as Harley Davidson� V-Twin, wet clutch lubrication, extreme pressure regions of gears and chains and rust common to short trips and storage.

AMSOIL MCV is multi-functional and fulfills the requirements of both domestic and foreign motorcycles. It outperforms other conventional and synthetic motorcycle oils.

AMSOIL, the leader in synthetic lubrication, produced the world�s first API qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL The First in Synthetics� to do the best job protecting your motorcycle.

Reduces Friction, Heat and Wear
In high heat conditions, engine protection is not sacrificed with AMSOIL Synthetic Motorcycle Oil. It has the best high temperature film strength (see High Temperature
Viscosity Protection graph below) of all oils tested and contains a heavy treatment of anti-wear additives to reduce wear regardless of the operating conditions (see Wear Comparison graph on reverse). AMSOIL MCV is thermally (heat) stable and contains maximum levels of oxidation inhibitor additives. It is extremely resistant to breakdown and engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

Provides Extreme Pressure Quality Protection for Gears
With AMSOIL MCV, there is no need for separate transmission or primary chaincase lubricants. It is absolutely shear stable and will not thin out from mechanical activity. AMSOIL MCV performs like a gear lube without the negative effects of extreme pressure additives. In the FZG gear test, AMSOIL MCV achieved a perfect score with a �zero� wear rating (see photos below).

Delivers Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage such as roller bearing failure, uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to engine oils. Unlike many motorcycle oils, AMSOIL MCV contains special anti-rust agents. It passes the ASTM D-1748 humidity cabinet rust test and clearly demonstrates superior rust protection (see photos below).

Rust Test ASTM D-1748 AMSOIL 20W-50 (MCV)	Rust Test ASTM D-1748 Castrol GPS 20W-50

AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) is recommended for Harley-Davidson, Buell, Victory, Ducati, BMW, Aprilla and Triumph motorcycles calling for a 15W-50 or 20W-50 viscosity, providing superior protection in engines, transmissions and primary chaincases.

Technical Service Bulletin: AMSOIL Recommended Oils for All Harley-Davidson Models (49k PDF)

AMSOIL 10W-40 Synthetic Motorcycle Oil (MCF) is recommended for Honda, Kawasaki, Yamaha, Suzuki, BMW, Husqvarna and KTM motorcycles calling for a 10W-40 or 20W-40 viscosity, providing superior protection in engines and transmissions.

Improved Transmission Protection

AMSOIL Synthetic Motorcycle Oils not only provide superior protection for motorcycle engines, they also provide superior gear protection, meeting API GL-1 gear lube viscosity requirements. AMSOIL Synthetic 10W-40 Motorcycle Oil (MCF) meets SAE 80W-90 gear lube requirements, while AMSOIL Synthetic 20W-50 Motorcycle Oil (MCV) meets SAE 90 gear lube viscosity requirements.

Viscosity is the most important characteristic of a lubricant. Motorcycle gears create a shearing effect that causes permanent oil viscosity loss. This thinning effect reduces the oil's ability to prevent metal-to-metal contact and wear. The stability and natural operating temperature ranges of the premium synthetic base stocks used to formulate AMSOIL Synthetic Motorcycle Oils eliminate shear and reduce wear. AMSOIL Synthetic Motorcycle Oils exhibit absolute shear stability as measured by the Kurt Orbon shear stability test.

The high temperatures and tight tolerances common to motorcycle applications also affect viscosity. The High Temperature/High Shear (HTHS) Test (ASTM D-4683) measures a lubricant's viscosity under severe high temperature and shear conditions. The more resistant an oil is to high temperature viscosity loss, the better it protects, and even a HTHS difference of 0.1 cP makes a significant difference.

AMSOIL Synthetic Motorcycle Oils exhibit higher HTHS viscosities than competing conventional and synthetic motorcycle oils. As seen in the graphs, AMSOIL Synthetic 20W-50 and 10W-40 Motorcycle Oils displayed the highest High Temperature/High Shear viscosities in their respective test groups, providing motorcycle engines and transmissions operating in the harshest conditions with superior protection against wear and viscosity loss and eliminating the need for separate gear case oils as recommended by some competitors. Synthetic 10W-40 may also be used in two-cycle transmissions.

Excellent Wet Clutch Performance
Many motorcycles utilize a clutch that is immersed in the motor oil. The friction modifiers present in many automotive motor oils and the extreme pressure additives present in EP gear lubricants produce a low coefficient of friction between the clutch discs and plates, resulting in clutch slippage and glazing. Slippage leads to increased operating temperatures and reduced clutch life. AMSOIL Synthetic Motorcycle Oils are formulated without friction modifiers, providing positive clutch engagement, longer equipment life and reduced temperatures. AMSOIL Synthetic Motorcycle Oils meet the clutch compatibility requirements mandated by JASO MA. AMSOIL 20W-50 (MCV) contains no friction modifiers and promotes smooth shifting and positive clutch engagement. AMSOIL MCV controls heat and prevents slippage and glazing, and its high TBN resists acids that can degrade clutch material, helping improve clutch life

Excellent Corrosion Protection

Most motorcycles spend the majority of their lives either parked or in storage, but most motorcycle oils fail to address corrosion problems. Corrosion protection during storage and in humid conditions is essential to extending equipment life. AMSOIL Synthetic Motorcycle Oils are formulated with specialized additive technology that not only protect against corrosion and acids during operation, but also provide exceptional protection during storage. The ASTM D-1748 Rust Test measures a lubricant's ability to protect against rust and corrosion. A standard metal reference coupon is immersed in the test oil before being placed in a humidity cabinet for 24 hours at 120 degrees F. As seen in the photos, the reference coupon treated with AMSOIL 20W-50 Synthetic Motorcycle Oil showed no signs of rust and corrosion, while the competitor failed the test.

Outstanding Heat Resistance

Motorcycles operate in demanding, high heat conditions that require robust high temperature deposit control additives. While many conventional oils break down and oxidize when faced with high temperatures, causing formation of carbon and sludge deposits, AMSOIL Synthetic Motorcycle Oils effectively withstand oil break-down and oxidation, keeping equipment running cooler and minimizing oil consumption, thickening and emissions. Air-cooled engines get especially hot while idling in traffic, commonly reaching temperatures up to 240 degrees Fahrenheit. The extra margin of protection provided by AMSOIL Synthetic Motorcycle Oils is especially important for hot running air cooled motorcycle engines.

Foam Control

High engine speeds and transmission gears in motorcycles churn the oil, suspending air and causing foam. When this oil and air mixture is drawn into a loaded area, the air compresses and decreases the thickness of the oil film, compromising wear protection. In addition, suspended air promotes oil oxidation, reducing its service life. AMSOIL Synthetic Motorcycle Oils greatly reduce foaming to provide long term lubricating protection in high speed, high RPM conditions.

Robust Additive Levels

Recent automotive motor oil regulations have limited certain additive levels, including the anti-wear additive known as ZDDP. ZDDP is an extremely effective anti-wear, anti-oxidant additive, and reducing its level results in compromised wear control and shortened service life. Because motorcycle applications require robust additive systems to control wear and oxidation, use of an automotive motor oil or an automotive motor oil re-labeled as a motorcycle oil compromises protection and performance. AMSOIL Synthetic Motorcycle Oils are overtreated with robust additive packages, including high levels of calcium, phosphorus, zinc and additional oxidation inhibitors, to extend oil life expectancy, provide unmatched engine cleanliness and greatly reduce wear.

AMSOIL Synthetic Motorcycle Oils are recommended for twice the manufacturer's recommended drain interval for on-road motorcycles.

The Four Ball Wear Test (ASTM D-4172) determines the wear protection properties of a lubricant. The smaller the average wear scar, the better the wear protection provided by the lubricant. AMSOIL Synthetic Motorcycle Oils produce significantly smaller wear scars than competing motorcycle oils, providing unsurpassed protection against engine wear, reducing maintenance costs and extending equipment life.

Cost Effective

AMSOIL Synthetic Motorcycle Oils provide excellent cost effectiveness and are cost competitive with competing high end motorcycle oils. The unmatched protection and performance provided by AMSOIL Synthetic Motorcycle Oils is excellent insurance for today's expensive motorcycles and custom bikes.

AMSOIL Quality Impresses Harley Riders

Although Harley-Davidson Motorcycle Company routinely tells its customers they must use �Harley-specific� motor oils and lubes, some riders are realizing AMSOIL keeps the popular bikes running cooler and smoother.

Jim Murphy and Jim White, partners at a Lehman Trike Conversion business in Martinsburg, W. Va., spread the word that AMSOIL makes the best products � even for Harleys.

�Trikes are a huge business,� White said. �Our business increased 200 percent last year.� He attributes that to older riders and those with disabilities that require modifications to allow them to continue riding. The shop specializes in those modifications needed for handicapped riders. (View the website at www.mjtrikes.com.)

Partner Jim Murphy summed up his feelings about AMSOIL products recently while talking with a group of customers at the parts counter of the local Harley dealership.

�If there is any single way to significantly improve the Harley-Davidson motorcycle, put AMSOIL in the engine and transmission,� Murphy said.

The partners recommend AMSOIL 20W-50 Synthetic Motorcycle Oil for the bikes and 75W-90 Gear Lube for the gear box. They�re also selling a lot of the AMSOIL Shock Therapy Light Suspension Fluid for the front forks.

White uses those products in his 1993 Heritage Softail Nostalgia, one of only 2,700 manufactured as a special edition Harley. The bike is attached to a fullsized sidecar. That�s a lot of pull on the machine, he said, but AMSOIL makes his bike run cooler and perform better than other oils or lubricants ever have.

�My Harley, with a sidecar, is getting 40 miles per gallon. I think AMSOIL makes a huge difference,� he said.

He�s heard increased mileage claims from some of his Gold Wing customers too.

Murphy and White opened their shop in 1998. While their specialties are trike conversions and custom builds for riders with handicaps, they also service and maintain cruisers and street bikes of every brand and model.

Harley owners are hard sells, White acknowledged. In fact, he said, most motorcycle riders tend to stick with products they�ve used and believed in for years.

He and Murphy are of the same ilk, so they understand. �The first two customers you had to convince were us,� White said. �The products that we sell are the result of satisfactory testing on our own motorcycles. We do not sell products that we do not totally believe in.�

White first used AMSOIL motor oil in the 1970s when he was a semi-professional go-kart racer. In January 2002, he met Direct Dealer Ralph Graul at a bike show and remembered how well the AMSOIL product performed in the karts.

He installed AMSOIL motor oil in his 1993 Harley-Davidson FLST Cowglide that was running hot, 220 to 230 degrees in the summer, and had a �klunky� transmission. �I changed the engine oil, primary and transmission oils to AMSOIL and immediately noticed a smoother shift in the transmission and a temperature drop of 20 to 30 degrees,� White said. �I was impressed, but I still hadn�t done my own testing. For the next 2,500 miles the shifting got better and better.�

Murphy tested AMSOIL lubricants in his 1994 Harley-Davidson FXLR, with 60,000 plus miles on the engine.

�This motorcycle has been meticulously maintained throughout its entire life,� Murphy said. �The transmission was making some gear noise and was getting harder to shift, and the engine had a whining noise in the updated cam and breather gears.

�Immediately, the transmission shifted like butter and no more gear noise . . . and the persistent gear whine in the engine also miraculously disappeared.�

They stock other brands of motor oils in the shop, for the hard-to-convince. �But AMSOIL outsells it all,� White said.

Educating customers, according to White, is one of their most important jobs.

AMSOIL literature available in the shop often gives his customers the information they need to make informed choices.

�I�ve never had one customer come back and claim that AMSOIL lubricants don�t do what the company says they will do,� White said.

Customer Sold on AMSOIL Quality and Value.

That's what today's savvy consumers want.

According to marketing analysts, the average consumer no longer accepts general sales pitches full of empty promises. The Internet gives consumers instant access to nearly every possible product or service. They look for quality information, conduct price comparisons and then make buying decisions.

The bottom line: more bang for their buck. And when that consumer is raising seven children, top quality products and savings are an even greater priority.

Scott Boring, Oakfield, N.Y., has seven children with his wife Teri. He's looking for quality and savings to keep his 1997 GMC Yukon, with a 5.7 litre V-8 engine that "isn't noted for gas mileage," running down the road carrying his large family as efficiently as possible.

A friend told Boring about AMSOIL products. He promised better gas mileage - an important selling point with today's high gasoline prices - more efficient performance and longer life.

The vehicle had 40,000 miles on it when Boring installed AMSOIL products bumper to bumper.

"I did it all at one time, just to see the difference," Boring said. He installed AMSOIL Severe Gear 75W-140 Synthetic Gear Oil, used AMSOIL Engine Flush and then installed AMSOIL 10W-40 Synthetic High Performance Motor Oil and AMSOIL Universal Automatic Transmission Fluid.

"I especially like the ATF," Boring said. "The truck shifts smoother and the transmission is quiet. All you hear is the tires on the ground. I've tried other synthetics, lots of them. I just never saw any difference. But, with AMSOIL, I saw a difference right away."

The first tankful of gasoline increased his mileage from 15 mpg to 20.5 mpg. "I swear I didn't believe it," he said. "I'm averaging between 19 and 21 mpg all the time.

"This stuff is awesome and I'm letting all my friends know about it."

AMSOIL Customers Appreciate Greater MPG

Although results vary because of a variety of factors, a common denominator among AMSOIL motor oil users is an improvement in fuel economy.

Independent testing reveals that AMSOIL Signature Series 0W-30 motor oil passes the API Energy Conservation Sequence VI test with a rating 38 percent higher than the API minimum specifications.

"The test results show that AMSOIL has the potential to save energy by conserving fuel," said Technical Services Manager Ed Kellerman. "In most cases it can increase mileage, but at the very least you're getting superior engine protection."

Ralph Sites, a police officer in Rustburg, VA, said he put AMSOIL 10W-40 Synthetic Motorcycle Oil in his 2002 GL 1800 Honda Gold Wing when it had 4,550 miles on the engine. "I had been getting 30 miles per gallon," Sites said. "I was supposed to be getting 40 to 45 miles per gallon."

His first oil change to AMSOIL improved his mileage to 38 miles per gallon. At 6,500 miles on the engine, after replacing the final drive oil with AMSOIL Severe Gear 75W-90 Gear Lube, he improved to 40 miles per gallon.

"I switched to AMSOIL for the long-term gain. The improved gas mileage was just a bonus. AMSOIL is less expensive than Honda's synthetic and I don't have to change it as often. It's a win-win situation."

He bought the bike new in January 2002 and had put 12,000 miles on it in August. He said the improved mileage he's gotten since switching to AMSOIL has saved him $102 just in gasoline.

Jeff Bailey in Fulton, Mo., said his 1996 Lexus GS300 with 81,000 miles on it also gained fuel efficiency when he switched to AMSOIL motor oil.

"The car wants premium gasoline," he said. "I drive about 18,000 miles a year. I ordered your synthetic product and absolutely astounded.

"I was used to getting about 20 mpg overall and having a little low-rev torque."

Since switching to AMSOIL motor oil, Bailey gets 24 mpg and uses regular gasoline.

"The engine feels even more flexible," he said. "I've used AMSOIL now for my wife's anemic Camry 2.2 litre and have calculated that I have saved about $120," he said. "Thanks AMSOIL for an awesome product. You have a customer for life."

Likewise, Lance Okeson of St. Paul, Minn., gained miles per gallon after switching to AMSOIL motor oil in his 1995 Cutlass Supreme.

Okeson made the switch after learning about AMSOIL from a customer of his at a quick lube where he works. His customer was so enthusiastic about AMSOIL, Okeson did some research on the AMSOIL Website and decided to try the products. A trip from the Twin Cities to Fargo, N.D., in a steady 17 mile-per-hour wind, and back showed him an increase from 24 mpg to 30.5 mpg.

"I have never gotten 30 plus mpg with that car," Okeson said. "I have two other vehicles that I switched over to AMSOIL motor oil. One is a 4x4 and the other is an old muscle car. I switched the transmissions and the differentials in those vehicles as well."

ASE Master Technician Sold on AMSOIL

Mark Deschner, Friendswood, Texas, is an ASE Master Technician and Manager of the West Pear Land Tire & Auto Store.

He recently was able to demonstrate the superior quality of AMSOIL Synthetic Lubricants when he had to change out a leaking intake manifold on his 1991 Chevrolet 1/2 ton pickup truck, with more than 183,000 miles on the original engine.

"When my lead technician took the intake manifold off, for the first time ever, he couldn't believe how clean the lifter valley and the top of the cylinder heads were on my truck," Deschner said.

The technician thought Deschner may have changed it before. But Deschner assured him he had never had the intake off before.

"He always made fun of me for only changing the oil once a year and the filter twice a year," Deschner said. "I think that seeing how clean the intake and cylinder heads are in my truck has changed his mind about AMSOIL products. I've always believed in them and my truck runs AMSOIL for all lubricant needs."

He uses AMSOIL 10W-40 Synthetic Motor Oil, EAO24 Absolute Efficiency Oil Filter, TS31 2-Stage Air Filter, GF111 Fuel Filter, 80W-90 Synthetic Gear Lube, Universal Automatic Transmission Fluid, Synthetic Multi-purpose Grease, P.I. Performance Gas Additive, Rain Clear Windshield Protectant and Bosch windshield wiper blades.

"As you can see, I have pretty much converted the entire truck over to AMSOIL products," Deschner said.

Preferred Customer Sold on AMSOIL Quality

Peter Virgona of Merrick, N.Y. is a self-proclaimed oil enthusiast. �I do a great deal of reading and research, always looking for the best oil,� Virgona said. �The more I read the more I realized AMSOIL was the best �true� synthetic I could buy. After using Mobil 1 since 1986, I made the switch to AMSOIL.�

Virgona is a warehouse worker, but he has many years of experience working on cars.

He drives a 1999 Ford Crown Victoria that has nearly 98,000 miles on the engine. He switched from Mobil 1 to AMSOIL 5W-30 Synthetic Motor Oil (ASL).

�The difference was immediate and significant,� Virgona said. �The idle became much smoother. There are times I can�t tell if the car is running. It also became much more responsive to the gas pedal, so much more responsive my wife asked me what I did to the car.�

Virgona has owned the car for almost nine years. �Not surprisingly, the gas mileage improved significantly,� he said. �This car always averaged 15 miles per gallon going back and forth from work. It now averages 16.5 mpg. That�s a 10 percent increase. I truly didn�t expect such a big change.�

He waited to report his findings until after he had driven the car at least 5,000 miles �to confirm that the numbers are average and not just a fluke.�

Virgona also has installed Ea Air and Oil Filters in his vehicles.

He told his sister-in-law about AMSOIL and then changed her oil over to AMSOIL 5W-30. She drives a 1996 Dodge Caravan with a 3.0 litre V6 engine. According to Virgona, she had always used conventional motor oil with regular oil changes every 3,000 miles.

�Nonetheless, she had a significant amount of sludge that was obvious under the oil fill cap,� he said. �She also experienced a very loud lifter noise that would come and go. Presumably, the sludge was affecting the oil circulation to the lifters.�

Oil consumption in the van was also increasing, using about one quart every 1,500 to 2,000 miles.

�I switched the van to AMSOIL and put in a new filter,� Virgona said. �Within 1,000 miles the lifter noise was all but gone. By 3,000 miles, virtually all the sludge was gone. I drained and refilled the oil a second time with AMSOIL 5W-30. The oil consumption is now down to one quart every 3,000 miles, with no more lifter noise.

�I am very happy with AMSOIL and plan to use it from now on. I recommend it to anyone who wants a great synthetic oil.�

Virgona buys his products through the AMSOIL website. �I always get my product within 48 hours,� he said. In fact, he just had a case shipped to his father in-law in Florida because he believes in AMSOIL products and wants others to experience their benefits. In fact, he�s considering becoming a Dealer.

Virgona respects that he can get detailed technical information about AMSOIL just by checking the website. �AMSOIL puts out performance test results for everyone to see. I definitely appreciate that.

�People are usually very, very loyal to AMSOIL. They know it�s the best.�

AMSOIL Gives Life to a Sweet Old Cadillac. Making a skeptic into a believer again.

Dear AMSOIL,

I thought you might appreciate hearing my AMSOIL story. When the opportunity arose last year to purchase my mother-in-law's 1987 Cadillac DeVille, I jumped at the chance. A true low mileage survivor, it was in near pristine condition. I was proudly showing it off to a mechanic friend when he said, "Uh-oh, you bought an HT-4100? Good luck buddy."

After much research I understood what he meant. The HT-4100 was rumored to be one of the most troublesome engines Cadillac ever built. The problems are numerous: an aluminum block with cast iron heads that expand and contract at different rates causing premature head and intake gasket failure, coolant loss into the oil, and finally main and rod bearing failure. They also have a heavily loaded distributor gear, weak timing gears, and sludging issues.

My first thought was, if ever an engine needed AMSOIL, it's this one. I first heard about AMSOIL at the old Brohman Dragway in the late 1970s from a fellow racer who swore by it. For the past 10 years, I've used various synthetic oils with favorable results, but never AMSOIL. Then I talked with Dave Mann, the AMSOIL Dealer in my home town, and told him my story. Having spent 19 years as a lubrication specialist with Ford, Dave knows his stuff. He made several recommendations, and shared with me his excellent e-book on motor oils.

I also asked around at the Cadillac owners group I belong to, and almost every one of them said, "Don't buy AMSOIL! It's too expensive and won't do you any good. You need this or that oil with this or that additive," and so on. So who was I to believe?

Having spent over 25 years in advertising and marketing, I have a strong skepticism for extravagant claims made by manufacturers. Usually, when you hear impressive adjectives like "advanced" and "superior," someone just wants your money or your vote (or both). So I read the science; from AMSOIL and from several independent studies. I came to the conclusion that it really is an excellent product. It also intrigued me that one of the primary sales points made by AMSOIL is to convince you to buy LESS of their product. That kind of marketing is contrary to anything I've experienced, and elevates AMSOIL's credibility level exponentially.

I switched the Cadillac over to AMSOIL 5W-30 (ASL) last fall, then put in AMSOIL 10W-30 (ATM) this spring (even though it's not a turbo, I like the extra wear protection offered by this formula). Rather than letting the oil go a full year, I change it every six months, during which time it accumulates about 6,000 miles. My dad was an auto mechanic and taught the 3,000-mile oil change rule like it was the 11th commandment - that kind of conditioning is hard to overcome. With this frequency, I still spend less money than if I changed the oil on a three-month/3,000-mile schedule. I use the money I save to have drain samples tested by an independent lab each time.

The Deville now has 50,000 miles and runs like a fine Swiss watch. I have not had a single problem with the 'troublesome' HT-4100 engine. It runs roughly 10 degrees cooler than with regular oil, and my gas mileage has increased by 10%. It has become my mission to get 200,000 miles from this car. With AMSOIL, I might just make it.

As an addendum, I also recently switched my wife's 2003 Oldsmobile Silhouette minivan to AMSOIL. Since we've owned it, this car has had a lifter clatter for the first 10 seconds on cold starts. Literally, on the first start after putting in AMSOIL, the clatter was gone.

Thanks AMSOIL. By making a superb product that truly does what you say it will do, you've given new life to a sweet old Cadillac, and made a believer out of this devout skeptic. (see photos of car and engine)

HDT Sets AMA Land Speed Record with AMSOIL

Hayes Diversified Technologies (HDT), located in Hesperia, California, produces diesel powered tactical military motorcycles for the U.S. armed services as well as the UK and EU NATO countries. Founded in 1961, the company originally manufactured electro-mechanical switches and relays to the military & aerospace industries.

The new HDT motorcycles are diesel machines combining both power and environmentally friendly performance efficiency. We are talking about a bike that gets 100 miles to the gallon AND can do 100 mph.

The HDT team was out on the Bonneville Salt Flats earlier this month, striving to establish new national and world records. Displaying the AMSOIL colors while going through the paces at Bonneville, they offered up quite a number of very strong endorsements with virtually no prompting. We noticed an increase in horsepower right away when compared to Delvac 1,� said Fred Hayes, founder/CEO of HDT. What was quite surprising was the condition of the engine after a 50-mile run-in and over 120 full-throttle dyno runs. The camshaft bearings, the small and large end rod bearings, didn't even look like they had been run. During that series of dyno runs, we registered the highest horse-power and torque readings ever.�

Dave Anderson, AMSOIL Technical Product Manager, had flown to Bonneville to witness and participate in the pursuit of new land speed records. Hayes said to Anderson, "Our testing proved that AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil provided better cam bearing lubrication, better transmission operation and less blow-by than our previous oil. We picked up just over one horse power at the rear well." This is a 3.7% increase and worth a 1 tooth higher gear ratio. In addition, it appears that overall coolant temperature was down about five degrees. That is roughly a 2.5% decrease in operating temperatures.

Very few bikers would be opposed to increased horsepower with lower operating temps, simply by switching over the lubricants.

With over a year of testing, we have found that AMSOIL products continually outperform all other lubricants. AMSOIL provides improved performance, increased fuel economy, lower oil consumption, and significantly reduced engine wear in all operating conditions.

AMSOIL Boosts Bottom Line for Grain Hauler

Burnell Keller of Castroville, Texas hauls a lot of corn. Saving downtime and maintenance costs boost his bottom line.

Since the 1960s, Keller Grain, Inc., at Castroville has bought high quality white and yellow corn from local farmers and trucked it to processing plants across the state of Texas. "These trucks put on about 12,000 miles a month," said Keller, the company's owner.

He was running Exxon XD3-30 motor oil in his Freightliner and changing it every 10,000 miles. He heard AMSOIL products could cut his operating and maintenance costs in half, provide better fuel economy, easier starts and extended oil drains at least three times longer than he was getting.

"We were fixing to extend the drain to 15,000 miles," Keller said. "But a sample of the Exxon motor oil analyzed at 10,000 miles came back saying the oil needed to be changed. I said, let's give AMSOIL a whirl."

After an engine flush, Keller installed AMSOIL 15W-40 Heavy Duty Diesel and Marine Oil in his Freightliner, with more than 400,000 miles on the engine.

"We did this procedure three times at a 15,000-mile analysis and filter change only," Keller said. "Each time the oil sample report came back saying the oil was good for continued use."

After the third round of analysis, the oil was changed. Keller plans to continue with 15,000-mile analysis and filter changes and to continue to use the same oil for an interval of 50,000 miles.

"That's about five times longer than before," Keller said. "It's very good. Keller Grain is now convinced that AMSOIL is a superior product and that anybody can save money using AMSOIL products."

New Life for Dodge Ram

Preferred Customer Lyle Reinier from Mesa, Ariz. has been using AMSOIL products for four years with complete satisfaction. He said that when he started using them in his 2001 Dodge Ram they �changed the way it ran.�

Now Reinier drives a 2004 Dodge Ram. He uses AMSOIL Synthetic 5W-30 in the engine, AMSOIL Synthetic Universal Automatic Transmission Fluid in the transmission and 80W-140 Long Life Gear Lube.

�AMSOIL has given this truck life that it was hiding before,� said Reinier. Reinier said the Ram now pulls stronger and runs smoother than it did before. He made the switch to AMSOIL when the truck hit the 3,000-mile mark. �What comes as a surprise to me is that my Dodge dealer had no problem doing a complete drain and fill with AMSOIL,� said Reinier.

Reinier said the dealer removed all the Dodge transmission fluid and refilled the truck with AMSOIL ATF. �Within a mile or two I could feel the transmission was smoother and showed a difference in how it performed,� said Reinier.

Reinier also uses AMSOIL in his dirt bikes. He and his wife have been using AMSOIL 0W-40 Formula 4-Stroke since it was introduced. Within the last year, Reinier performed a big bore and a valve job on their bikes in search of more power.

�The insides of the cases, transmission gears and crank shafts were all like brand-new,� said Reinier.

Reinier said the cylinder walls of each bike still showed some cross hatching from the
