GUMOUT Multi-System Tune-Up 16oz 510011

All engines develop performance issues over time, whether they’re gas, diesel or ethanol. Carbon deposits reduce performance and fuel economy. Water and ethanol corrode key engine parts. Gumout Multi-System Tune-Up is the most advanced treatment for all types of engines, from cars to lawn mowers. It cleans and conditions using premium ingredients, like PEA (polyether-amine), to help maximize performance, fuel economy and engine life. Multi-System Tune-Up can be added in the gas tank, the crankcase or via induction.

Directions: Add to fuel: For optimal results, add entire can to the tank. Fill the tank with fuel and run to near empty before refueling. One pint treats 18-21 gallons of all types of gas or diesel fuels. Add to oil: Add one ounce per quart of oil. Immediately start engine and run for 5-10 minutes to mix completely. Vacuum Intake Cleaner: May be used with engine decarbonizing equipment through the vacuum system to clean intake manifold, valves and combustion chamber.
