Royal Purple High Performance Full Synthetic Engine Oil 5W-30 1 Quart

Royal Purple® High Performance engine oils carry the current API and ILSAC engine oil licenses, as well as the GM dexos1™* gasoline engine oil approval. Enhanced additive technology prevents metal-to-metal contact beyond both GM dexos1™* and ILSAC GF-6 specs. Advanced additive chemistry helps reduce Low Speed Pre-Ignition in today’s turbocharged Gasoline Direct Injection engines. A low coefficient of friction results in optimized fuel efficiency. Patented anti-wear additive chemistry minimizes the harmful effects exhaust gases pose to the catalyst. Patented additive technology prevents the white sludge and lubrication starvation that can occur with higher concentration gasoline-ethanol blends. No rust observed in standard industry testing. *dexos1™ is a registered trademark of the General Motors Corporation.
