IC5 in a tractor [SOLVED]

No, IC5 is not going to be effective in a carbureted engine. (It’s formulated for fuel-injected engines. Most modern cars and trucks have fuel injected engines, so if you have a bottle of IC5 already, use it in a car or truck).

For a tractor with a carburetor, I’d use Sea Foam Motor Treatment or High Mileage. It cleans and lubricates the entire fuel system and works great in carbureted engines. Add at least 2 oz per gallon of fuel.

Hope that helps!
