Royal Purple® API-licensed engine oils carry the current API and ILSAC engine oil licenses, as well as the GM dexos1™* gasoline engine oil approval.
BETTER WEAR PROTECTION
Enhanced additive technology prevents metal-to-metal contact beyond both GM dexos1™* and ILSAC GF-5 specs
INCREASED FUEL EFFICIENCY
A low coefficient of friction results in optimized fuel efficiency (the fuel economy of our 5W-30 meets the fuel economy requirements of a 5W-20 oil)
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
