Royal Purple HPS Series Motor Oil (MPN: 31520)

High performance synthetic oil for modified engines and superior protection.

Royal Purple HPS Series motor oil is engineered to enhance performance and meet the rigorous demands of high performance and modified engines. This synthetic oil is particularly suitable for vehicles that are no longer under manufacturer warranty, providing an elevated level of performance and protection. The unique formulation of HPS allows it to outperform both leading synthetic and conventional lubricants in various engine types, including gasoline and diesel engines.

Fortified with a high concentration of zinc and phosphorus anti-wear additives, along with Royal Purple's proprietary Synerlec technology, HPS motor oil significantly improves metal-to-metal contact under extreme conditions. This results in increased viscosity in response to pressure, ensuring optimal engine protection. The advanced synthetic solvency of HPS reduces engine deposits, maintaining engine cleanliness and efficiency.

Additionally, HPS motor oil features exceptional oxidation stability, which extends oil life and allows for longer intervals between oil changes. This not only saves time and money but also minimizes environmental impact. With its ability to improve sealing between piston rings and cylinder walls, HPS maximizes horsepower and torque while optimizing fuel economy. It also provides superior corrosion protection, making it suitable for valve trains that require enhanced safeguarding due to high lift and high ramp rate camshafts.
