BETTER WEAR PROTECTION ? Enhanced additive technology prevents metal-to-metal contact beyond both GM dexos1* and ILSAC GF-6A specs
INCREASED FUEL EFFICIENCY ? A low coefficient of friction results in optimized fuel efficiency (our 5W-30 meets the fuel economy requirements of a 0W-20 oil; our 0W-20 meets fuel economy requirements of a 0W-16)
BETTER PROTECTION FOR VEHICLE EXHAUST EMISSIONS EQUIPMENT ? Patented anti-wear additive chemistry minimizes the harmful effects exhaust gases pose to the catalyst
IMPROVED COMPATIBILITY WITH FUELS CONTAINING ETHANOL ? Patented additive technology prevents the white sludge and lubrication starvation that can occur with higher concentration gasoline-ethanol blends
SUPERIOR CORROSION PROTECTION ? No rust observed in standard industry testing
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.
