Royal Purple: HPS® Series High Performance Engine Oil

Fortified with a high level of zinc/phosphorus anti-wear additive, HPS® series motor oil from Royal Purple is designed to maximize the performance and meet the demands of high performance and modified engines. When combined with Royal Purple’s proprietary Synerlec® additive, this formulation outperforms leading synthetic and conventional lubricants in gasoline and diesel engines.

HPS® engine oil offers exceptionally high film strength to dramatically reduce engine and valve train wear and heat, all while improving the piston ring/cylinder wall seal to maximize base HP/torque and optimize fuel economy. Outstanding oxidation stability extends oil life to save you time and money. The formulation also reduces deposits to keep your engine clean and offers superior corrosion protection.
