Maximize Engine Performance with Royal Purple HPS Street Motor Oil

If you’re looking for superior engine protection and longer oil change intervals, Royal Purple HPS Street Motor Oil fits the bill. Made for high-performance, modified, and diesel engines, this synthetic oil offers advanced wear and corrosion protection, plus improved performance and service life. Here’s how:

Royal Purple HPS Street Motor Oil can withstand the higher pressures found in a performance engine, providing a better seal between the piston ring and cylinder wall to reduce compression loss and friction. That can mean more horsepower and torque—who doesn’t want that?

Royal Purple’s proprietary Synerlec® additive technology and high levels of ZDDP (zinc/phosphorus) provide superior anti-wear characteristics for motors with high-lift roller and flat tappet camshafts. The oil’s synthetic solvency reduces engine deposits for cleaner internals and increases engine life. It’s exceptional oxidation stability extends oil life and helps protect engines from heat-related degradation, which allows for more miles between oil changes, saving you some coin.
