ok, thanks, i will check it out

 

ok, so seafoam has diffrent applications. do you guys think it is just as good as a fuel cleaning addative when added to the fuel tank? what the hell is this stuff? and why does it have so many diffrent uses...yet looks like it is something found in my grandads garage?

 

Usually, "fuel cleaning addative" is mainly just fuel system cleaner AKA injector cleaner, and is ment to help clear up your fuel pump and injectors, poured into your gas tank. Sea foam is more for cleaning your engine internals, cyliners, head, intake, by spraying it right into the motor and letting it all burn out....or so I think.
