good fuel:
14ish MPG city
20-21 MPG highway
current crap fuel:
12.5 to 13 mpg non blown
13+ blown with hard launches and full throttle fun. can't keep off the gas to see what a tank would be easily driven
?? MPG highway...not any to test it out with

14.5~15mpg mixed driving to/from work empty in the back. I average closer to 14 when I'm hauling crap.
18 mpg tops on freeway averaging 70~75mph the entire 30gallon tank, empty in the back. I got about 17mpg on the same trip fully loaded with 4 people and the back full of crap.
My '05 FX4 screw is bone stock and I consider myself to be easy on the gas pedal. I only use Shell or Chevron gas.
36.5K on the truck now, and mileage has not gotten any better or worse the whole time, although mileage seems to have dropped <0.5mpg on the latest PCM flash earlier this year which made my shift points a little later and smoother.
I drive without my 90lb spare tire except on long out-of-town trips. That's less mass (and less gas needed) that has to be accelerated around all day. Does it dent mpg's? I doubt it's measurable, but the truck does feel a little lighter.

[troll] encourage all your neighbors and friends to take the bus, carpool, and buy/drive more Priuses and sub-micro-compacts. There'd be plenty o'cheap gas left for the rest of us gas hogs 
Actually, it was nice when gas was $4.70+ around here. I could actually see over the horizon when I'm driving. Now the weekend SUV's are back out in force on weekdays.

I have an 07 5.4 4x4 with 3.73 gears, supercrew cab and 6.5 box
I have never calculated its in town mileage, rarely ever drive it in town, I take the car for that.
On the HWY if I am gentle it gets 18 MPG, driving a little quicker it gets 16 MPG....towing in hilly country I can get as bad as 8 MPG.

so what do you think is up if all you guys are getting at least 3-4 mpg better? could it be because it sat for over a month at the dealership cuz he droves like grand pop when I'm in the truck but who knows what he does when hes alone. thought id ask since hes been bugging me.

Driving style, hills, and elevation can cause widely varying gas mileage. Someone who lives at sea level, never climbs hills, and does 99% highway driving at 60 mph could probably get 22-23 mpg. Someone who lives at 6000 ft and drives over 10,000 ftmountain passes every day at 80 mph will probably get 8 mpg...
