AMSOIL has a documented history of innovation and leadership. In 1972, AMSOIL introduced the first American Petroleum Institute rated 100% synthetic motor oil for automotive applications. AMSOIL was the first to introduce a concept of "extended drain intervals" with a recommended 25,000-mile / 12-month drain interval. AMSOIL Synthetic lubricant technology has been field tested over the last 35 years in the most severe driving conditions. Including family fleets, over the road big rigs, towing, hauling and of coarse racing.

AMSOIL Synthetic Motor Oils dramatically outperform conventional petroleum motor oils. Synthetic lubricants are engineered, synthesized lubricants consisting of 100% PAO Formulated Basestock Technology, and may be made to fulfill virtually every lubricating need. The molecular uniformity of synthetic lubricants promote superior lubrication and friction reduction, which in turn promotes superior heat control, wear control and energy efficiency. Molecular uniformity also helps synthetics maintain their protective viscosity in high-temperature operations, which also promotes superior wear control. Because they are derived from pure chemicals, synthetic lubricants contain no contaminants or molecules that “don’t pull their own weight.� Synthetic Lubricants contain no paraffin or wax molecules like conventional lubricants
