World's first API-qualified synthetic motor oil leader in synthetic lubricant technology! The only 25,000-mile oil!!
The introduction of the world's first synthetic motor oil to meet American Petroleum Institute service requirements in 1972 set all-new standards for motor oil quality. AMSOIL synthetic motor oil outperformed conventional petroleum motor oils on all counts. It was clear from the start that this innovative product would play a major role in engine performance and engine life.
AMSOIL has remained steadfast in its commitment to quality and precision lubricant engineering, leading the charge over the past four decades with many industry firsts. This quality-first commitment has driven the introduction of numerous synthetic lubricants, premium filtration technologies and fuel additives that provide tangible, real-world value.
Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and has followed the AMSOIL lead with introductions of synthetic motor oils of their own. They spend millions of dollars advertising their "new" and "revolutionary" products. No one, however, can match AMSOIL experience. Accept no substitutes – AMSOIL is "The First in Synthetics®".
