Seafoam killed my mileage?
Now that I've seafoamed the car, I've noticed a definite loss in my MPG...I cleaned the plugs and I'm gonna change the oil soon but should a noticeable drop in mileage occur?

I've heard it mentioned that Seafoam could free up some crud that was actually helping seal or do something before it was dislodged in whatever way. It could easily be for another reason, though.
