AMSOIL founder and industry pioneer Al Amatuzio began commercially selling synthetic motor oil for automotive use in 1968. In 1972, a breakthrough came when AMSOIL 10W-40 Synthetic Motor Oil became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. It outperformed conventional oils on all counts, signaling a new age in lubrication science. We’ve remained loyal to our founding principles of excellence, integrity and innovation ever since. Our customers look to AMSOIL for synthetic lubricants that offer innovative answers to the greatest challenges their vehicles and equipment present. To prove product performance, we test products in our mechanical and chemical labs, in addition to using field trials involving the most demanding applications, including taxi fleets, over-the-road transports, wind turbines and racing vehicles.
