Superior Foam Control

Resists foaming to deliver the correct engineered fluid film thickness, which reduces premature gear and bearing failure and results in gears and bearings lasting as designed.

Proven Water Resistance

Water is one of the biggest contributors to gearbox failure. It can cause sludge formation, additive drop-out, viscosity loss and filter plugging.

Excellent Filterability

Easily filtered using either 5- or 10-micron full-flow oil filters and is also recommended for use with 3-micron by-pass filters.

American Innovation

As one of a few independently owned oil companies, we’ve always stood apart from the big oil companies. We maintain the freedom to formulate products based on performance, not price. The result is a complete product line of full-synthetic lubricants that helps you push the limits of vehicle performance, power and speed.

Since day one, we’ve been on the leading edge of the industry. Our first breakthrough came in 1972 – AMSOIL 10W-40 Synthetic Motor Oil, the result of years of research and inspired by aerospace technology, became the first full synthetic motor oil in the world to meet American Petroleum Institute service requirements. We’ve since remained steadfast in our pursuit of developing products that help you get the most out of your vehicles.
