Needless to say I'm a Seafoam fan.
I've done Seafoam intake cleanings on every vehicle I've owned. I even mixed a quart of gasoline with a quart of seafoam in a 7 gallon pig. Charged the pig to 90 psi and ran my 96 Tahoe off it till the pig was empty (Pulled the fuel pump relay and pinched the return line). Never ran smoother. Ran a half gallon of Seafoam through the last two tanks of fuel in Lena. One of those tanks included a double dose of Techron. I like both products, they are the only additives I use in my fuel.
