Motor Oil Info

For over three decades, AMSOIL INC. has been recognized as the leader in synthetic lubrication technology. AMSOIL was the first to introduce a synthetic motor oil qualified by the American Petroleum Institute, the first to recommend 25,000 mile/one-year drain intervals, the first to recommend 35,000-mile/one-year drain intervals, and the first to implement a system for dramatically increasing drain intervals with oil analysis.

Decades of research, laboratory analysis and millions of engine miles have kept AMSOIL the leader in automotive applications for synthetic lubrication. Although the results have paid off in maximizing efficiency and minimizing waste, more can be done. AMSOIL is the leader in synthetics and will continue to explore ways to reduce environmental impact through continued research, analysis and product development.
