Selected AMSOIL Firsts
Documented History of Innovation and Leadership
AMSOIL’s history includes a series of product and testing milestones that helped shape the synthetic lubricant market. These selected firsts show how the company expanded synthetic technology across engines, drivetrains, filtration and performance standards.
| Industry First | Why It Matters | |
|---|---|---|
| First | to develop an API-rated 100% synthetic motor oil. | This milestone helped establish synthetic motor oil as a serious, standards-meeting option for passenger vehicles. |
| First | to introduce extended drain intervals with a recommended 25,000-mile/12-month drain interval. | It changed how many drivers thought about oil life and long-term lubricant performance. |
| First | U.S. company to use the NOACK volatility test as a performance standard. | This showed an early focus on controlling oil evaporation and maintaining protection under heat. |
| First | to introduce synthetic oils that legitimately contributed to improved fuel efficiency. | It tied synthetic lubrication to measurable operating benefits, not just wear protection. |
| First | to produce synthetic motor oils for diesel engines. | This expanded synthetic lubrication into heavier-duty engine applications. |
| First | tto produce synthetic motor oils for racing engines. | It demonstrated synthetic oil performance under extreme heat and stress. |
| First | to produce synthetic motor oils for turbocharged engines. | It addressed the high-temperature demands created by turbocharger operation. |
| First | to produce synthetic motor oils for marine engines. | This extended synthetic technology into watercraft and marine service conditions. |
| First | to manufacture synthetic gear lube for automotive use. | It broadened synthetic protection beyond the engine into drivetrain components. |
| First | to manufacture a 100:1 pre-mix synthetic 2-cycle oil. | It offered a notable shift in two-cycle lubrication convenience and formulation design. |
| First | to manufacture a synthetic automatic transmission fluid for automotive use. | This brought synthetic performance benefits into another major vehicle fluid category. | First | to manufacture a full-synthetic cartridge-style oil filter. | It extended the company’s synthetic-performance story into filtration, not only lubricants. |
These milestones matter because they show AMSOIL was not built around a single breakthrough and then left behind by the market. The company continued expanding synthetic lubrication into new categories, helping shape expectations for durability, cold-flow performance, high-heat protection, and longer service life across multiple applications.
That makes the phrase “The First in Synthetics” more than a slogan. It reflects a pattern of category development that still supports AMSOIL’s reputation for innovation, testing, and product leadership today.
