Royal Purple HPS Synthetic High Performance Street 5W30 Motor Oil - 1 Quart

The Royal Purple HPS motor oil is a synthetic oil specifically formulated for high-performance, modified, vintage, and late-model engines. It addresses increased valvetrain loads and elevated power levels by providing reliable protection for severe street and light competition applications. This oil is fortified with optimized levels of ZDDP (zinc dialkyldithiophosphate) and advanced Synerlec® technology.

The HPS oil offers industry-leading anti-wear performance, reducing metal-to-metal contact. It provides greater lubricity and a low coefficient of friction to maximize engine performance and slows the breakdown of oil for long-lasting protection. Its advanced synthetic solvency helps reduce engine deposits and keeps engines clean. It also reduces Low Speed Pre-Ignition (LSPI) in turbocharged Gasoline Direct Injection (GDI) engines.
