AMSOIL, the Proven Leader in Motor Oils

AMSOIL provides a wide variety of high quality synthetic motor oils tailored to fit the needs of your automobile, SUV, performance vehicle, motorcycle or 4-stroke engine.

When the first can of AMSOIL 10W-40 appeared on the market in 1972, it signaled the birth of an entire industry. AMSOIL synthetic lubricants have expanded the boundries of lubrication science and redifined the performance possibilities of modern machinery and engines.

AMSOIL will save you money and give you the peace of mind that comes from using the best. Today's engines produce more power from a smaller plant with a smaller radiator and a smaller volume of oil to cool and lubricate them. They need more protection from heat than conventional oils give them. Conventional oils keep engines from failing most of the time, but there's a big difference between marginal failure prevention and the total wear protection that AMSOIL delivers!
