HPS is recommended for use in gasoline and diesel automotive, commercial fleet and stationary industrial engines. 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 vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection. Royal Purple HPS oils are fortified with a high level of zinc/phosphorus anti-wear additive and a generous dose of Royal Purples proprietary Synerlec additive technology. These unique formulations enable HPS oils to outperform leading synthetic and conventional lubricants in both gasoline and diesel engines. 5W30. 6 Quarts. PERFORMANCE ADVANTAGES Exceptionally high film strength which reduces engine wear and reduced 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 stability extends oil life and allows for more miles driven between oil changes saving you time and money. Advanced synthetic solvency reduces engine deposits and keeps engines clean. Outstanding wear protection for valve train components, including performance roller lifter and high lift flat-tappet camshafts and lifters. Superior corrosion protection.
I had high hopes for Royal Purple, but my engine actually started to sound louder after using this 5W30 oil. I followed all the instructions but it hasn’t worked for my vehicle like I thought it would. Disappointed, to say the least.

Great oil for performance cars
I've been using Royal Purple 5W30 in my muscle car for a few months now and I really notice the difference in smoothness. It performs well in high temps and the engine stays quiet. I love that it comes in a 6-quart case too; less running around for oil changes!

Solid engine oil but delivery was slow
This Royal Purple oil does its job well, keeping my engine running smoothly. However, I was disappointed with the shipping time; took over a week to arrive. Still, the quality is there, and I plan on using it for my next oil change soon.

Noticeable performance boost!
Switched to Royal Purple 5W30 for my truck and I can feel the power. The acceleration feels better and the engine noise has reduced significantly. The 6-quart case is convenient for my needs. Totally worth the investment!
