AMSOIL specializes in developing synthetic lubricants that offer innovative answers to the greatest challenges vehicles and equipment present. The extraordinary performance of AMSOIL synthetic lubricants in a range of markets – automotive, powersports, industrial, racing and more – have made our influence in the industry unmistakable and our brand highly respected.

AMSOIL introduced the first synthetic motor oil with an API (American Petroleum Institute) Service Classification in 1972. Since that time, AMSOIL has varied and expanded its product line.
AMSOIL Synthetic Lubricants are fuel efficient, extended life lubricants manufactured from select synthetic base stocks and special purpose additives. These lubricants provide significant improved overall performance benefits than conventional petroleum oils.
Certainly. AMSOIL Motor Oils may be used in any mechanically sound gasoline or diesel fueled engine. Basically, that means they are excellent for use in any vehicles engine.
Absolutely not! Manufacturers' warranties are based on 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.

In a nutshell, the auto manufacturers' and your "friendly" dealer actually want your vehicle to wearout and have a finite life within a specific targeted period of time so you have to buy a new one, or come to the dealer for expensive repairs. AMSOIL Motor Oils, ATF and gear lubes have been proven for over 25 years and hundreds of millions of miles to significantly extend the life of a vehicles engine, transmission, axles, gears and bearings. We bet you find that hard to believe? Read our complete article The Auto Industry's Best Kept Secret and peruse the rest of this website and you should have no doubt in your mind that this is true. The auto manufacturers and dealerships ARE NOT looking out for your best interests!
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 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!
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 and other synthetic 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 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 actual increase.
Yes, AMSOIL Motor Oils are compatible with all other synthetic or petroleum motor oils.
AMSOIL Synthetic Motor Oils are highly resistant to the destructive effects of heat, and do not break down like petroleum oils. This means that AMSOIL Motor Oils can provide much longer drain intervals than conventional lubricants.
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.
There are no special requirements. However in older vehicles or those with high mileage, it may be advisable to use AMSOIL Engine Flush first. This will ensure that the engine is clean and free of any accumulated contaminants which might have an effect on the service life of AMSOIL Motor Oils. In all cases, it is good judgement to install a new AMSOIL Oil Filter every time you change oil.
