High Performance Oil
Royal Purple Motor Oil is a blend of synthetic oils that aims to
improve engine performance and protection, reduce emissions and increase fuel economy.
Because it adheres to engine surfaces after shutdown, it provides protection during startup.
Royal Purple claims its product also increases horsepower and torque while reducing wear and
heat within the engine.
“I would recommend this product, as it increased the gas mileage of all my vehicles and
extended the time between oil changes.” —Jim Goffinet, Pendleton, Ind.
“I used Royal Purple in all my cars and even my backhoe! The engine didn't bog down under load; it remained cooler than usual.”
—Robert Hunt, Hooper, Utah
