Royal Purple 12540 5W40 Multi-Grade Motor Oil Synthetic 1 Quart Case
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 combines premium base oils with enhanced additive technologies to create high performance motor oils that optimize engine protection beyond both Dexos1 and ILSAC GF-5 requirements, increase fuel efficiency, protect emission systems, improve compatibility with fuels containing ethanol, and offers superior corrosion protection. No special procedures are necessary when upgrading to Royal Purple. Royal Purple motor oil is fully compatible with mineral or other synthetic oils. Royal Purple recommends waiting until the manufacturer’s first scheduled oil change in new gasoline engines before upgrading to Royal Purple.
For those seeking enhanced performance in vehicles not under warranty, we recommend our HPS Series of high performance motor oils with our proprietary Synerlec additive technology.
For racing applications, we recommend our XPR – Extreme Performance Racing motor oil.
Royal Purple motor oil is compatible with other mineral and synthetic motor oils. It’s available in 0W-20, 0W-40, 5W-20, 5W-30, 5W-40, 10W-30, 10W-40, 15W-40 and 20W-50 weights. Royal Purple also makes mono-grade motor oils in SAE 30, SAE 40 and SAE 50 weights.
