Royal Purple Motor Oil is recommended for use in all four-cycle gasoline engines and both two-cycle and four-cycle diesel applications including cars, trucks, motor homes / RVs, boats, commercial fleet and stationary industrial diesel engines.
Royal Purple Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple’s proprietary, synthetic Synerlec additive technology.
Synerlec additive technology greatly reduces engine wear, including ring, cylinder and bearing wear. It is extremely tenacious, adheres to engine surfaces and remains after shutdown, which provides protection upon initial startup.
Environmentally Responsible: Royal Purple Motor Oil extends oil drain intervals. Less oil is purchased and less oil is being disposed of—It’s good for your vehicle, and good for the environment!
Multi-Grade Oils: 5W20, 5W30, 10W30, 10W40, 15W40, 20W50
Royal Purple Motor Oils are compatible with other mineral and synthetic motor oils.
Tech Tip: Royal Purple’s motor oils are API certified and will not void new car warranties. Royal Purple recommends waiting until the manufacturer’s first scheduled oil change or a minimum of 2,000 miles in new gasoline engines before using Royal Purple. Allow 8,000 to 10,000 miles before use in diesel engines.
Originally developed for demanding auto race applications, our premium oil filter is rapidly becoming a favorite among consumers for its durability and easy removal. We've changed oil filters and several of our product development technicians are sportsman class drag racers. They insisted we offer an oil filter that corrected the headaches they experienced over the years changing oil filters. We have all been there: Whether it's remembering where that disappearing canister tool is; or having oil leak all over your garage and yourself; or finally giving up and pounding a screwdriver through the filter just to get if off. Each of our automotive and marine oil filters comes with a 1 nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. Our motorcycle and ATV oil filters come with a 17 mm nut. Our oil filters use resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration. High filter flow rates are important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. When the engine is circulating oil at high GPM rates, the high-flow oil filter helps reduce the loss of pressure through the filtering process. To satisfy the demands of racers, our oil filter has many features over and above the requirements of most vehicles. We use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The heavy-duty construction will withstand higher oil pressures found only in racing environments without bursting. The drilled hole on the nut is for a safety wire attachment. Required for many types of racing, the safety wire prevents blown oil filters from falling on the track and representing a hazard to other race vehicles. This extra engineering offers peace of mind for consumers who want only the best.
