Seafoamed the g/f's explorer with 147k on the clock, smoked up the entire neighborhood. Did mine at 75k, not much came out. Might depend on how much carbon build up, how long it soaks, etc. Just a guess though. It made me feel better seeing that smoke come out the tailpipe, knowing that crap wasn't gunking up my engine anymore, but as far as SOTP difference, didn't really notice one.

 

Used that stuff in weedeaters, mowers, my car and truck and it seems like it really helps if you have a trashed up fuel system. Used it once in my dads 67 mustang 302 and it made a decent smoke show but didnt smoke out the neighborhood. Really good stuff IMO.

 

True, but if you take a lit match to Seafoam it will ignite, whereas water will extinguish the match...think about what you're saying. You may see similar results with something like washer fluid, as it contains alcohol, but not water. If you mix water and gasoline, it will separate.

 

I just sent Silver-mod-o a text the other day that said "Seafoam is awesome" haha
i put half a can thru the intake and let it sit for a couple hours. It smoked like crazy and didnt stop for 3 miles.
I run it thru my 4wheeler every now and again when i have some left over.
