AMSOIL synthetic lubricants deliver wear protection, engine cleanliness and fuel efficiency conventional oils simply can’t match. They help your vehicles run better and last longer.Learn More
What is synthetic motor oil? AMSOIL synthetic lubricants are chemically engineered to form pure lubricants. They contain no contaminants or molecules that don’t serve a designed purpose. Their versatility and pure, uniform molecular structures impart properties that provide better friction-reduction, optimum fuel efficiency, maximum film strength and extreme-temperature performance conventional lubricants just can’t touch.
Conventional lubricants, on the other hand, are refined from crude oil. Contaminating elements such as sulfur, nitrogen, oxygen and metal components such as nickel or vanadium are inherent to crude oil and cannot be completely removed through the refining process. The oil refining process separates the various types of molecules in the oil by weight, leaving molecules similar in weight but dissimilar in structure, reducing performance.
AMSOIL shields your automobile with 75% more engine protection against horsepower loss and wear than required by a leading industry standard*, extending the life of vital components like pistons and cams.Read the full story
*As required by a leading industry standard. Based on independent testing of AMSOIL Signature Series 0W-20, in ASTM D6891 as required by API SN specification.
