bad gas mileage
when people run seafoam through an engine it has been known to damage some, no matter how careful the person thinks they are. i know a few people that work at the alexandria pontiac that avoid the stuff like the clap unless its to put in the fuel tank
well i have personally used seafoam in my gass and oil before..and it does help alot. ive never had any problems with that stuff
yeah, ive done the gas thing, but never oil... or putting in throught the IM (which is where a lot of concerns are). just remember, this is the same company that makes PB and that shit will eat through almost anything
