Royal Purple HPS Multi-Grade Motor Oil; 5W30 – 1qt Bottle
Demand peak protection and power from your performance vehicle with Royal Purple HPS (High Performance Street) 5W-30 Synthetic Motor Oil (P/N: 31530), available at Straight Six Imports. This 1-quart bottle of premium oil is engineered for demanding applications, making it the perfect choice for modified import street cars, turbocharged vehicles, and track day enthusiasts.
Royal Purple HPS is fortified with a high level of Zinc/Phosphorus (ZDDP) anti-wear additive and their proprietary Synerlec® technology, creating an exceptionally strong synthetic film. This unique combination dramatically reduces friction, minimizes wear, and lowers operating temperatures in engines subjected to high heat and pressure, such as those with aggressive camshafts or forced induction.
Key Performance Advantages for Enthusiast Engines:
-
Maximum Wear Protection: Elevated ZDDP levels provide superior anti-wear protection for valvetrain components like flat tappet and high-lift roller camshafts.
-
Increased Output: Improved sealing between the piston ring and cylinder wall maximizes combustion efficiency, translating to measurable horsepower and torque gains.
-
Superior Thermal Stability: Resists thermal breakdown and oxidation, ensuring lubrication integrity and allowing the engine to run cooler.
-
Advanced Cleaning: Strong synthetic solvency reduces harmful engine deposits and keeps engine internals exceptionally clean.
-
Viscosity: 5W-30 is an ideal viscosity for balancing cold-start protection with high-temperature film strength in many modern performance import engines.
