The Origin of High-Performance Synthetic Motor Oil

AMSOIL was founded on a simple yet revolutionary idea: synthetic lubricants offer superior performance for combustion engines. This insight came from Lieutenant Colonel Albert J. Amatuzio, a jet fighter squadron commander who witnessed firsthand the benefits of synthetic oils in aviation. These advanced lubricants delivered three key benefits in extreme operating conditions:

  • Reduced friction and wear
  • Consistent performance in extreme temperatures
  • Resistance to chemical breakdown during prolonged use

Inspired by these results, Amatuzio set out to bring the same innovation to the automotive world—paving the way for what would become the best synthetic oil products available for consumer and commercial use.

Pioneering Innovation in Engine Protection

In the early 1960s, Amatuzio began extensive research and development of synthetic engine oils. His breakthrough came in 1972, when AMSOIL became the first synthetic motor oil to meet the American Petroleum Institute’s (API) service requirements. This milestone marked a turning point in the industry, redefining standards for engine protection, oil durability, and vehicle performance.

Compared to conventional petroleum-based motor oils, AMSOIL synthetic lubricants deliver:

  • Superior wear protection for longer engine life
  • Enhanced fuel efficiency and engine cleanliness
  • Extended oil change intervals for cost savings and convenience
