The choice depends on what you use your vehicle for. Consider these six (6) basic types of uses:
For everyday driving, we recommend our signature high performance synthetic oil, which exceeds the toughest industry standards, providing 6 times increase in valve train wear protection* and 2 times greater resistance to oil breakdown*. Licensed by American Petroleum Institute (API) and International Lubricants Standardization and Approval Committee (ILSAC) it is warranty compliant for newer vehicles and offers the best protection possible in an API-licensed motor oil.
For vehicles with 75,000 miles or more, choose a premium full synthetic motor oil specially formulated for older vehicles that helps restore lost engine performance. Over time, seals can shrink and leak. HMX reconditions seals, providing a little swell and flexibility to older seals. It also provides a higher level of anti-wear additive than Royal Purple API-licensed oils thanks to Royal Purple’s proprietary Synerlec® additive technology, further enhancing performance and protection.
For car enthusiasts with high-end, modified engines and for vehicles no longer under manufacturer warranty, HPS series motor oil is specifically formulated with Royal Purple’s proprietary Synerlec additive technology to provide a higher level of protection and maximize performance.
Recommended for use in various racing applications, XPR offers the ultimate in lubricant performance and protection. XPR offers greater wear protection on startup, increased protection against LSPI and outstanding rust and corrosion protection.
Engine builders have grown increasingly concerned that current engine oils that are API licensed for new cars and trucks do not provide adequate wear protection for freshly built performance engines, particularly those using flat tappet camshafts and lifters. Royal Purple Break-In Oil is formulated to provide the critical wear protection needed by the engine valve train and camshaft while allowing new piston rings to quickly seat to the engine cylinder walls.
A high-performance diesel engine oil made specifically for emission-controlled diesel engines. It is an API CK-4 approved engine oil that greatly performs beyond CK-4 standards. It maximizes component life by protecting against valvetrain, cylinder liner and piston ring wear, reducing power loss and helps maintain optimum efficiency. Its superior thermal and oxidation control prevents oil degradation and bearing corrosion, leading to extended drain intervals. It improves fuel performance by protecting against deposit and sludge formation to ensure continued engine performance in all operating and weather conditions.
