Royal Purple: High-Performance Street Synthetic Motor Oil

High-Performance Street (HPS) synthetic motor oil from Royal Purple is specifically formulated to maximize performance and meet the demands of high-performance and modified engines. HPS is recommended for vehicles no longer under manufacturer warranty—and for those seeking a higher level of performance and protection.

Available in 5W-20, 5W-30, 10W-30, 10W-40, and 20W-50 viscosities, Royal Purple’s HPS is fortified with a high level of zinc/phosphorus anti-wear additive and the company’s own Synerlec additive, allowing it to surpass leading synthetic oils and conventional lubricants for both gasoline and diesel applications.
