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.

have you try toyota fuel injector cleaner? I never heard of seafoam before I will look into that but I use toyota fuel injector cleaner it a can you but a certain tool and hook up through the fuel filter and disable the fuel pump and let the can run out and the car stall. I use it and I get 400 miles on highway on a fuel tank of gas.
