Royal Purple Synthetic Motor Oils

Royal Purple® Motor Oil is recommended for use in all four-cycle gasoline engines and both two-cycle and four-cycle diesel applications including cars, trucks, motor homes / RVs, boats, commercial fleet and stationary industrial diesel engines.

Royal Purple® Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec® additive technology.

Synerlec® additive technology greatly reduces engine wear, including ring, cylinder and bearing wear. It is extremely tenacious, adheres to engine surfaces and remains after shutdown, which provides protection upon initial startup.
