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 API-licensed oils meet warranty requirements of most passenger car and light trucks sold in the U.S./North America. Royal Purple motor oil is compatible with synthetic and conventional motor oils.

Royal Purple meets both dexos1TM* and ILSAC GF-5 specifications in critical lubrication performance:

• Better wear protection - Enhanced additive technology prevents metal-to-metal contact beyond both dexos1TM* and ILSAC GF-5 specs
• Increased fuel efficiency - A low coefficient of friction results in optimized fuel efficiency
• 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
