Diesel Engine Oil


Extreme Oil For Extreme Engines

Every diesel owner knows that the most important thing you can possibly do to extend your engine life is regular oil changes with quality oil. Diesel engines work hard so their oil needs to work harder.

This specially formulated Fully Synthetic Diesel Engine Oil provides unmatched protection for your engine and will extend the lifespan of everything from a Duramax to PowerStroke to Cummins.


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
