I have seen many videos extolling the benefits of Seafoam. Lots of before and after camera shots of valves, combustion chambers and such showing how well the product worked cleaning them up.
I was at the local AutoZone couple of weeks ago and they had the medium size bottles on sale. I picked up a couple. Added one to the F150 right before I sold it. Put the other in the Corvette.
My fuel mileage has always stayed consistent at 17.2. After only one full tank my fuel mileage has gone from 17.2 to 18.0 even. On the second tank now. I have been driving the exact same route to and from work. Same gas, same speeds. No other changes.
Curious to see if it keeps improving.

On a side note, my brother has a 350Z vert with the enthusiasts trim package. He said on his car he figured out that if he turns off the traction control when he drives he gains about one mpg. Anyone tried this?
