Our complete selection of PEAK® Motor Oils are formulated with high-quality petroleum base stocks and fortified with advanced additive technology. These advanced additives are consumed by the vehicle’s engine over the course of the oil’s lifespan or drain period. As the oil performs its job of trapping combustion’s harmful by-products it gradually becomes less efficient and effective. That’s why oil must be changed on a regular schedule and why an oil change is one of the most important, and easiest, vehicle maintenance tasks.

Meets all manufacturing standards and more.
