Deposits build up on intake valves, fuel injectors, and combustion chambers. This is a result of the low level of additives that are used in gasoline – even premium unleaded fuels. As these deposits accumulate, vehicle performance deteriorates. Fuel mileage decreases, octane requirements increase and drivability issues develop. This can occur in as little as 15,000 miles. Castle® Dragon Power™ is a one-step fuel system cleaner. It safely and effectively removes deposits from the entire fuel system including fuel injectors, intake valves, combustion chambers, intake manifold, and fuel rails. This patented formula is safe for all gasoline engines. Dragon Power™ reduces wear to internally lubricated parts, and is OEM approved. There is no harmful alcohol, kerosene, or other ingredients that would damage any fuel or emission systems components. Dragon Power™ will increase fuel economy, power, and performance. It will also reduce emissions, lower octane requirements, and improve overall drivability.
