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
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 lifeImproved 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
