GUMOUT 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.

Features

• Cleans port/indirect fuel injectors, intake valves and ports.
• Conditions upper cylinder to reduce friction and wear.
• Prevents future carbon buildup on intake valves and ports.
• Best for maximized performance and fuel economy, reduced upper cylinder wear.
