Royal Purple 44154 15W40 Multi-Grade Motor Oil Synthetic 4 Gallon Case
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.
