Innovation and Leadership

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 45 years in the most severe driving conditions, including family fleets, over-the-road big rigs, towing, hauling and, of course, racing.
