Fuel System Treatment
Carbon buildup across the fuel system can reduce the efficiency of engine combustion. Piston and cylinder wear at start up can harm parts and cause mileage robbing friction. Gumout® Fuel System Treatment removes carbon deposits from engine parts to maximize engine performance and fuel economy. Plus it lubricates the upper cylinder to enhance engine longevity and maximize MPG.
