Recognizing these same benefits would prove invaluable in combustion engines, Amatuzio began conducting serious research in the early 1960s. He soon developed and sold commercially available synthetic oils under a variety of names. The true milestone came in 1972 when AMSOIL became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. It set all-new standards for motor oil quality and outperformed conventional petroleum motor oils on all counts. It was clear from the start this innovative product would play a major role in redefining the performance capabilities of modern machinery and engines.
