Royal Purple's API-licensed Motor Oil combines premium base oils with proprietary additive technologies to create high performance motor oils that optimize engine performance. Royal Purple's API-licensed motor oil delivers superior protection and improves performance in gasoline and diesel engines. Royal Purple's API-licensed SN motor oil meets ILSAC GF-5 and Dexos1* performance requirements.
No special procedures are necessary when upgrading to Royal Purple. Royal Purple recommends waiting until the manufacturer's first scheduled oil change in new gasoline and diesel engines before upgrading to Royal Purple.
Royal Purple motor oil is compatible with synthetic and conventional motor oils. Available viscosities include: 0W-20, 0W-40, 5W-20, 5W-30, 5W-40, 10W-30, 10W-40, 15W-40 and 20W-50 weights. Royal Purple also offers mono-grade motor oils in SAE 30, SAE 40 and SAE 50 weights.
BETTER WEAR PROTECTION
Enhanced additive technology prevents metal-to-metal contact beyond both 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 OF THE EXPENSIVE CATALYTIC EMISSION SYSTEM
Patented ZDDP additives optimize emissions catalyst system life
IMPROVED COMPATIBILITY WITH FUELS CONTAINING ETHANOL
Patented additive technology prevents the white sludge and lubrication starvation that can occur with 20% or higher ethanol fuel
SUPERIOR CORROSION PROTECTION
No rust observed in standard industry testing
