SeaFoam..gotten some mixed responses from people. Options

[Badkarma]

soo my celica is still getting pretty horrible gas mileage.19 mpg currently. haven't changed the o2 sensor(s) yet, but it isn't throwing any codes either. changed plugs, wires, cap, rotor, fuel filter, air filter, alignment...


Now i would like to give Seafoam a try. its a pretty potent clenser from what i hear. id like to get some responses from you all. what were your results, and how did you use it? (fuel tank only, vacuum only, intake only?...all?)
my friend tried it and it ended up blowing his pcv valve clean off the truck. it got melted as well, idk if it was complete coincidence or not.

i plan on just trying it in the tank for now.. but let me know how it worked for you.

Thanks, Erich.

I agree with griffgirl. I was getting 23 mpg till I tried seafoam. Used it in the gas and didn't get much of a change. Used it through a vaccum line, like in that thread she posted and I get a regular 29 mpg. Stuff works great. Sounds like your friend either has really bad luck or didn't put something back together right
