Signature Series Max-Duty Synthetic Diesel Oil 5W-40 Gallon Jug

First in Synthetics

AMSOIL founder and industry pioneer Al Amatuzio built his company on the same principles that defined his career as a jet fighter squadron commander – excellence, integrity and strong leadership. In 1972, the breakthrough came. AMSOIL 10W-40 Synthetic Motor Oil, the result of years of research and inspired by 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. Accept no substitutes – AMSOIL is The First in Synthetics®.
