Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity, the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance. With a weight of SAE 5W-30, this oil has an SAE viscosity rating of 10 in cold temperatures and a rating of 40 at normal operating temperature. This oil is fully synthetic, meaning crude oil is not used in making it. Synthetic oil often provides superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil. Royal Purple HPS Series motor oil is specifically formulated to maximize performance and meet the demands of high performance and modified engines. Fortified with a high level of zinc/phosphorus anti-wear additive and proprietary Synerlec additive technology, this unique blend outperforms leading synthetics and conventional lubricants. Available viscosities include 5W-20, 5W-30, 10W-30, 10W-40 and 20W-50. HPS is recommended for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection. Royal Purple's HPS Series of motor oil responds to increased pressure with increased viscosity. It's advanced additive technologies, such as Synerlec improves the condition of metal-to-metal contact under severe conditions for greater protection.

From the Manufacturer


Royal Purple HPS 10W-40 Synthetic Motor Oil

Royal Purple HPS Series motor oil is specifically formulated to maximize performance and meet the demands of high performance and modified engines. HPS is high performance street motor oil recommended for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection.

Royal Purple’s HPS is fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purple’s proprietary Synerlec additive technology. This unique blend enables HPS to outperform leading high performance synthetic oils and conventional lubricants for both gasoline and diesel engines.

Royal Purple HPS Series of motor oil responds to increased pressure with increased viscosity. Improved sealing between the piston ring and cylinder wall maximizes horsepower and torque. Its advanced additive technologies improve the condition of metal-to-metal contact under severe load. The advantages are clear. Take a look at the following photos:

HPS Advantages

Exceptionally high film strength dramatically reduces engine wear and engine heat to extend the life of your engine. Improved sealing between the piston ring and cylinder wall maximizes horsepower and torque and optimizes fuel economy. Exceptional oxidation stability extends oil life and allows for more miles driven between oil changes saving you time and money and reducing the impact on the environment. Advanced synthetic solvency reduces engine deposits and keeps engines clean for increased fuel economy and engine longevity.

HPS protects valve trains using roller or flat tappet lifters that require added protection due to high lift/ high ramp rate camshafts. It also provides maximum protection, extends engine life and ramps up efficiency. For vehicles under warranty, Royal Purple recommends its API-licensed oils available at retailers nationwide.
