Gumout 510011 Tune-Up, 16 oz Bottle

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 P.E.A (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.
