Just had #4 fuel injector and spark plugs replaced. Added Gumout fuel injector cleaner to the next tank of gas as per directions. Time for a new tank of gas. Can I add another Gumout?
Yes, Shouldn’t need to add another but won’t hurt anything either. If you are using the Expert Series Gumout Fuel System Cleaner it is even advertised:
- Best for maximized performance and fuel economy in one fill-up
- Cleans direct and indirect fuel injectors, intake valves and ports, piston tops, cylinder heads, combustion chamber
- Improves performance and maximizes gas mileage
- Prevents future carbon buildup
