Royal Purple Motor Oil delivers superior protection and improves performance in four-cycle gasoline and
diesel engines. It increases horsepower and torque, saves fuels and reduces heat, wear and emissions.
It has unsurpassed oxidation stability that allows for extended oil drains and fewer oil changes, which saves
you time and money and reduces the impact on the environment.
Royal Purple’s motor oils are API certified.
Royal Purple’s performance advantages come from a blend of synthetic oils plus Royal Purple’s
proprietary Synerlec technology. Royal Purple Motor Oil is
compatible with other mineral and synthetic motor oils. It’s available in 0W40, 5W20, 5W30, 5W40, 10W30,
