Royal Purple HPS High Performance Street Synthetic Motor Oil – 5W-30 | 1 Quart

Royal Purple HPS (High Performance Street) is a premium full synthetic motor oil engineered for performance, modified, and turbocharged engines that demand more than conventional oil can deliver. Fortified with elevated zinc/phosphorus (ZDDP) anti-wear additive and Royal Purple's proprietary Synerlec technology, HPS creates an exceptionally strong synthetic film that reduces friction, minimizes wear, and maintains lubrication integrity under the high heat and pressure conditions common in performance applications.

Key Features

• Elevated ZDDP Anti-Wear Protection: Higher zinc/phosphorus content than many conventional and synthetic oils provides superior protection for flat-tappet camshafts, high-lift roller cams, and performance valve trains operating under sustained high loads
• Synerlec Technology: Royal Purple's proprietary additive creates an exceptionally strong oil film that reduces friction and wear, particularly during cold starts and high-temperature operation
• Increased Output: Improved piston ring-to-cylinder wall sealing maximizes combustion efficiency for measurable horsepower and torque gains
• Superior Thermal Stability: Resists thermal breakdown and oxidation under sustained high-temperature operation — ideal for turbocharged and high-performance naturally aspirated engines
• Advanced Engine Cleanliness: Strong synthetic solvency reduces harmful deposits and keeps engine internals clean
• Full Synthetic Base: Premium synthetic base oils for superior performance across a wide temperature range
