The company's history is a checklist of industry firsts, and its legacy of research and innovation continues today. AMSOIL Founder and Industry pioneer Al Amatuzio built his company AMSOIL on the same principles that defined his career as a jet fighter squadron commander – excellence, integrity and strong leadership. AMSOIL 10W-40 Synthetic Motor Oil, the result of years of research and inspired b
y aerospace technology, 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. Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and followed the AMSOIL lead with introductions of synthetic motor oils of their own.
