FREQUENTLY ASKED QUESTIONS (FAQs)

QUESTIONS:	ANSWERS:
What are AMSOIL Synthetic Motor Oils?	AMSOIL Synthetic Lubricants are fuel efficient, extended life lubricants manufactured from select synthetic base stocks and special purpose additives. These lubricants provide improved overall performance characteristics when compared to conventional petroleum oils. (See the Technical Page on this site if you are interested in learning more about the fundamental properties of Amsoil lubricants.)
What AMSOIL products should I use for my Harley Davidson motorcycle?	See the Harley Specs page on this site, in particular, the oil chart and Amsoil Technical Service Bulletin.
Will using AMSOIL Engine Flush in motorcycle engines damage the wet clutch?	It may soften clutch materials to the point where clutch packages could be damaged, and is not recommended for this application.
What is the actual oil weight for the following suspension fluids: STL - Shock Therapy Light and STM - Shock Therapy Medium?	Shock Therapy Light corresponds to a 5 wt. and Shock Therapy Medium corresponds to a 10 wt.
Will AMSOIL Motor Oils void the warranty of a new motorcycle?	Absolutely not! Manufacturers’ warranties are based upon the use of oils meeting specific API Service Classifications, for example, SJ/CF. (AMSOIL lubricants meet the current API Service requirements and, thus, are perfectly suited for use in any new vehicle without affecting the validity of the new vehicle warranty.)
Are AMSOIL Motor Oils True All-Season Oils?	Synthetic oils are made to protect and perform better than petroleum oils at both high and low temperature extremes. That’s why every jet engine in the world is lubricated with synthetic oil. AMSOIL Motor Oils have extremely low pour points and flow readily at extremely low temperatures for easier winter starting and significantly reduced engine wear. At high temperatures, no conventional motor oil can compare to the overall protection AMSOIL Synthetic Motor Oils provide. That’s extremely important for today’s turbocharged and small, non-turbocharged engines!
Will using AMSOIL Motor Oils increase gas mileage?	Tighter government regulations and increases in engine manufacturers’ demands are calling for more fuel efficient lubricants. AMSOIL Motor Oils reduce friction and drag better than petroleum oils, resulting in significant fuel economy increases. In a recent 1.2 million mile demonstration, AMSOIL Lubricants showed a 4.5% increase in gas mileage. Other tests have shown increases of as much as 15% under certain weather and driving conditions. Yet, because every vehicle is different, as are driving habits and conditions, it is difficult to accurately project an exact increase.
Will AMSOIL Motor Oils decrease oil consumption?	Yes. When used in mechanically sound engines, AMSOIL Motor Oils can reduce oil consumption. Under test conditions, a reduction of as much as 42% was demonstrated for prolonged periods. However, this should not be taken to mean that AMSOIL Motor Oils are “cure-alls” for engines that consume oil because of mechanical problems.
Should oil additives or After Market products be added to AMSOIL Motor Oils?	No, they are not necessary! AMSOIL Motor Oils are formulated under the strictest quality control procedures using the optimal additive package to provide superior lubrication performance.
