too poor to wheel... :(

Ok so I broke down and bought some E3 spark plugs (review coming...) and when I was replacing the old ones they all looked ok except they had excessive gap!
I dropped on and it measured .055 and the rest ranged from .060 to .075.... now I was getting 16 MPG around town in my 06 LJ with 33 inch tires and 4.56 gears and the 6 speed manual tranny...

So now with the E3's what would people be guessing my mileage is going to be?
