February 18, 200917 yr My friend swears by the seafoam and we put some in my car and in my sister's car and in our truck. We did the intake method on the truck (98 chevy 350) and the sis's mustang 3.8 On mine I put it in the oil cause we couldn't figure out where to suck it in. I have read that 250-500 miles I will have to change the oil in my 3800. Any thoughts?
February 19, 200917 yr Yeah, it works..... But I've seen people screw up their cars doing it too.... So just be careful.......
April 16, 201015 yr there is an older couple that we know that has the same car as we do...08 taurus x AWD. we always compare mpg and such. he swears he gets 10% or more better mpg on running seafom through the tank on his trips.
