What specific milestone did Al Amatuzio achieve regarding synthetic motor oil in 1970?

Creation of the first complete synthetic motor oil with necessary additives

Al Amatuzio, the founder of AMSOIL, is specifically recognized for a crucial evolutionary step in synthetic lubricant history: moving beyond the base stock creation achieved decades earlier in Germany to produce a product ready for widespread automotive use. In 1970, his team successfully engineered the first *fully formulated* synthetic motor oil. This meant integrating the proven synthetic base stock technology, derived from PAOs, with a complete and necessary suite of additives—such as detergents, dispersants, anti-wear agents, and corrosion inhibitors—required to protect an engine during typical, everyday driving conditions, rather than just functioning as a neat base lubricant in a specialized industrial setting.
