Seafoam is more for cleaning valves and such and doesnt typically help with MPG's.

I have never experienced a mileage jump after using seafoam. I have noticed performance increases, smoother idles and the like, but never an increase in mileage.
There must be something else going on if you are getting such bad fuel economy.
