Royal Purple HPS 10W40 High Performance Engine Oil

Royal Purple HPS Series Motor Oil (with Synerlec) is specifically formulated to maximize performance and meet the demands of high performance and modified engines. HPS is recommended for use in gasoline and diesel automotive, commercial fleet and stationary industrial engines, and is particularly suitable for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection. These unique formulations enable HPS oils to outperform leading synthetic and conventional lubricants in both gasoline and diesel engines.

The HPS oils are fortified with a high level of zinc/phosphorus anti-wear additive and a generous dose of Royal Purple's proprietary Synerlec additive technology, which provide a number of performance advantages. Exceptionally high film strength helps to reduce engine wear and engine heat, extending the life of the engine. Improved sealing between the piston ring and cylinder wall maximizes horsepower and torque and optimizes fuel economy. The exceptional stability of the oils extends their life and allows for more miles driven between oil changes, saving time and money.

The advanced synthetic solvency of the HPS oils reduces engine deposits and keeps engines clean. They also offer outstanding wear protection for valve train components, including performance roller lifter and high lift flat-tappet camshafts and lifters, as well as superior corrosion protection.

Available in a 10W40 viscosity, Royal Purple HPS Series Motor Oil is offered in a 1 Quart size. The combination of its specialized formulation and performance-enhancing additives make it a reliable choice for high-performance and modified engines, as well as for those vehicles no longer covered by the manufacturer's warranty.
