1972 AMSOIL FIRST to
develop an API-rated 100% synthetic motor oil.
1972 AMSOIL FIRST to
introduce the concept of "Extended Oil Change Drain Intervals" (25,000-Miles).
In 1972 AMSOIL synthetic motor oil became the FIRST in the world to meet American Petroleum Institute (API) automotive service requirements setting all-new standards for motor oil quality, and went a step further introducing the concept of extended oil change drain intervals (Because in 1972 the oil was also capable of performing for 25,000-mile "extended oil change drain intervals", and it was the right thing to do for the consumer all while maintaining and providing long-term performance, wear protection and fuel economy, keeping engines clean and deposit-free, providing cold weather starts and protecting against rust and corrosion). And as they say the rest is history.
With that the Automotive Synthetic Lubricant Industry was born.
