Is it any good to put seafoam in your gas tank only???I dont want to put it in the intake or oil

 

in the tank it works just like a bottle of injector cleaner.

the smoke & results you'll read about are all related to it being sucked into the intake.

 

Good call on not adding it to your intake, or oil. There are just too many mixed reviews on the Seafoam. And besides, if your truck runs, and doesn't leak, and gets decent mileage, why mess with perfection?

 

what could possible happen if you put it through the intake besides hydrolocking it by being stupid? Ive done it and it worked fine. However Im not putting it in the oil cus my engine has sludge and i dont want to cause any leaks.
