Royal Purple API-Licensed Synthetic Motor Oil

Royal Purple’s API-licensed motor oil delivers superior protection and improves performance in gasoline and diesel engines. It combines premium base oils with proprietary additive technologies to create high performance motor oils that optimize engine performance. It also meets warranty requirements of most passenger car and light trucks sold in the U.S./North America.

Why Use API-Licensed Synthetic Motor Oil?

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 (the fuel economy of our 5W-30 meets the fuel economy requirements of a 5W-20 oil)

Better protection of the 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

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.
