How many miles can I go between oil changes in vehicles that use gasoline?August 17, 2018
Yes. Royal Purple currently offers many viscosity grades of API-licensed motor oils1. To allow for proper break-in of the engine, Royal Purple recommends waiting until the manufacturer’s first scheduled oil change or a minimum of 2,000 miles (3218 km) in new gasoline engines. Allow a minimum of 6,000 miles (9656 km) before using Royal Purple in diesel engines.
