AMSOIL Motorcycle Oil Vs Harley Davidson
Screamin Eagle Synthetic Oil
The 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 over 25 years, Harley Davidson has claimed its petroleum based Genuine H-D Oil is best for the unique requirements of Harley-Davidson's air-cooled V twin engines. However, laboratory testing has consistently revealed that Genuine H-D Oil does not provide the best protection possible for Harley-Davidson's engines.
Of course it is not in their best interest to make an oil that can double the life of your engine. They would sell fewer bikes and less parts and service.
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 engine protection possible for Harley Davidson motorcycles.
Screamin Eagle Synthetic Motorcycle Oil Caused 80% More Wear
Than AMSOIL 20W-50 Synthetic Motorcycle Oil
The Four-Ball Wear Test is the industry 's standard test method for measuring the wear preventive characteristics of a lubricant. Placed in a bath of the test lubricant, three steel balls are put into contact with a fourth ball in rotating contact at preset test conditions. Lubricant wear protection properties are measured by comparing the average wear scars on the three balls. The smaller the average wear scar, the better the protection.
Not only does AMSOIL Synthetic Motorcycle Oil offer 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 of up to twice the manufacturer's suggested interval, while Screamin ' Eagle is recommended for standard drain intervals, AMSOIL customers realize additional savings.
AMSOIL Synthetic Motorcycle Oils
- Reduce operating temperatures
- Increases Performance
- maximum protection against wear
- Extend Engine and transmission life
- Save money with extended drain intervals of up to two times the manufacturers recommendations.
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 30 years of experience providing superior lubricating 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 Motorcycle Oils.
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 Harleys.
The fact is, engine oil in Harley Davidson motorcycles 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 lubricating qualities of the oil and increasing wear.
The water, soot and acid by-products 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 Harley Davidson Oil. High-quality synthetic oils formulated with high-performance additives effectively withstand such contaminants, allowing motorcyclists to safely extend drain intervals.
In support of their about-face and the introduction of a synthetic oil, Harley maintains that the Motor Company has never supported the use of synthetic products in our vehicles because there has never been any test validations completed on the numerous formulations 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 HD/Buell motorcycles."
Although this is necessary marketing hype, Harley-Davidson's 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 from, or makes it better than, many other synthetic motorcycle oil formulations, except that Harley-Davidson is marketing it and directly promoting from the sales.
Formulated with top-of-the-line synthetic base stocks and high-temperature deposit 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.
