From starting line to checkered flag, Royal Purple synthetic engine oil is a trusted name in NASCAR, NHRA, World of Outlaws and Bonneville Salt Flats.

Racing engines require extra protection against super-extreme working conditions. Royal Purple’s proprietary additive technology Synerlec® allows our full synthetic oil to bind to metal surfaces. This relentless bond works to dramatically reduce engine heat and wear under the most severe loads. And the engine cleanliness provided by our Extreme Performance and Nitro Plus racing motor oils ultimately create more horsepower and more torque.
