One of the guys here has had it in his car for over a year and he hasn't had a problem.
yea see thats the thing, hes used it since he got the car. Now my thinking is this, it loosens up all the grim, but the amount of grim depends on how long you have had the car and the last time youve used seafoam. So i have 65,000 miles on my car (4 years) and never used seafoam so I image there will be alot of crap to burn. I don't want that crap to foul my o2 sensor....anyone have any experience with my situation?
