I put the whole bottle of Seafoam in my full gas tank yesterday morning. There still has not been any smoke coming out. Is it not supposed to smoke if you only put it in the gas tank? Does it even work if you ONLY put it in your gas tank?
Not much works at all in the gas tank. Our fuel systems are filtered twice & the dilusion is soooooo much.
Besides... Gasoline itself is a hell of alot better solvent than most of the "addatives"you can put in it!
