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 Royal Purple 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.
Jim
Goffinet, Pendleton, IN: “I would recommend this product as it increased
the gas mileage of all of my vehicles and extended the time between oil changes.”
Robert Hunt, Hooper, UT: “I used Royal Purple in my backhoe, and the engine didn’t bog down under load; it remained cooler than usual.”
