High Mileage Fuel System Rejuvenator

Thoroughly cleans entire fuel system of all high mileage gas-powered vehicles, including those exceeding 60,000 miles. Powerful detergents and H.E.S.T. solvents give one-tank clean-up of fuel injectors, intake valves, carburetor, and combustion chambers. Dissolves fuel residue and carbon deposits to restore lost power, reduce rough idle and hesitation, restore octane requirements, and improve overall drivability. Improves fuel economy, disperses moisture, and stabilizes gasoline.

Great for all 2-stroke and 4-stroke marine and small gas engines. Safe for use with catalytic converters, oxygen sensors, and all gasoline containing up to 15% ethanol, including E10 and E15.
