Yeah, I posted about doing it last weekend and got a nice bit of white smoke for a while. I'm still getting some pinging and knock retard when I blip the throttle so I might need another round. But what's strange is that I had a tank of 89 octane in the car, beat on it to burn off the seafoam and revved the car all over for a couple of days. Today I filled up expecting the gas mileage to be down a couple of mpg and to my surprise that tank actually was better than the previous one! I've been averaging a little over 18 mpg and this tank with the seafoam and me revving the heck out of it actually got almost 19 mpg and that's with no highway driving! It's good to clean the combustion chambers once in a while.
