I want to runs some SeaFoam this weekend before I change my oil. MY question is, how much of the 16oz can should I use (in the oil, vaccuum line, gas tank)? Thanks for the help! Nick

 

i usually put about half a can in a paper cup, then suck it up with the brake booster hose...seems to work good for me. drive around a while till your engine is up to temp,then suck up the seafoam,let it sit for a few hours,then go beat the bag out of it before you change your oil.

 

Thanks for the info. Thats what I will do. How long do you wait to change your oil? Immediately or a couple hundred miles?

 

Hell, I run about 3 cans through my brake booster line. After that I change my oil. Then put a little SeaFoam in my gas. Made my truck run so much smoother. Got rid of the small amount of knock I was seeing with AutoTap too!
