Works like a champ i allways have used seafoam on anything i have with a motor

 

it does work to an extent. It's no miracle in a can, but I can tell you that after using it - vacuum and gas - my XJ does seem to run a little smoother. I think it's mainly due to the injectors getting cleaned. Is it worth the money, I say yes, but I also say do a thorough job by pulling the injectors and let 'em soak in a bowl of the stuff overnight, open 'em up with a 9v, and then spray 'em out with compressed air and carb cleaner. I'd rather the junk get out of my engine rather than run through it.
