The Castle Ultimate Tune Up has been proven in laboratory and field research to clean the entire fuel system, giving the vehicle restored power in less than an hour.

The service specifically targets fuel injector deposits. When these deposits are eliminated, proper fuel flow is restored for higher operating efficiency. During the process, carbon build-up on intake valves are removed, restoring a smooth idle.

Castle offers a variety of Fuel System Services for multiple types of drivability problems. The specific Fuel Service you need will be determined by the particular environment you live in and the severity of your driving habits.
