Seafoam.

I have a 1996 Grand Cherokee, 6 cyl with 192,xxx miles on it. All in all it runs really well( finally...took care of the classic Jeep stalling issues) I'm considering running Seafoam thru my gas tank and oil. Should I? How much in each?? Is it OK to do with my mileage?? My gas mileage is bad, only mid 14's, I'm hoping to get more mileage per gallon? So....what do you think??

Good question. Seafoam has finally made it into Canada, and I've got a bottle just dying to be tried. Not sure if it's snake oil or not, but a lot of the guys on here swear by it. Where I live, if it put out half the smoke people says it does, I'd probably lose a fair bit of hair. Think I'll find a big open field, far from anyone and give it a try.

works great through the throttle body and through the vacuum lines, even through the gas tank. As for oil, with that many miles, it could cause more issues than it fixes. If the motor was neglected and is leaking any oil, it will make it worse. oil leaks get partially clogged by carbon build up and the seafoam eats through the build up and makes the leak worse.

If your motor isnt leaking any oil and has been well maintained, it shouldnt cause a problem. If its already leaking, it will make it worse. Otherwise, running it through the gas, vac lines, and TB is fine and works great.

Best improvement for gas milage that I've seen is both upper and lower O2 sensors. As far as seafoam in crankcase, only if it is currently not using/losing any oil between changes, and then I'd say for 6 quarts, about 9 ounces of seafoam, call it a little more then half a bottle.
