How long have AMSOIL lubricants been on the market?

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. 

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. 

What are AMSOIL Synthetic Blend Motor Oils?

AMSOIL Synthetic Blend Motor Oils are a blend of synthetic fluids and petroleum oils. They are combined to form an all season motor oil that demonstrates many of the performance features of synthetic lubricants. 

Can AMSOIL Motor Oils be used in any engine?

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 vehicle’s engine. 

Will AMSOIL Motor Oils void the warranty of a new vehicle?

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 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. 

Are AMSOIL Synthetic Motor Oils and petroleum motor oils compatible?

AMSOIL synthetic motor oils are fully compatible with all petroleum motor oils, and there is no danger in mixing the two. Mixing AMSOIL and petroleum oil, however, is not a recommended as a general practice. Performance and long drain intervals will be sacrificed and the oil should be promptly changed, at maximum, within the next 3,000 miles. 

Why are AMSOIL Motor Oils capable of extended drain intervals?

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. 

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. 

Is there a recommended procedure for changing to AMSOIL Motor Oils?

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 Absolute Efficiency Oil Filter (EaO) every time you change oil. 

Should Oil Additives or After Market Products be added to AMSOIL Motor Oils?

No, they are not necessary! AMSOIL Motor Oils are properly formulated under the strictest Quality Control procedure to provide superior lubrication performance.
