Finally got my truck, a 5.4 4x4 Screw 3.73, after waiting 12 weeks! I've heard alot of talk of these trucks getting 13mpg or less. I'm still on my first tank of gas and am getting 15mpg according to the computer. Should I be happy? I know these mileage computers are notorious for being inaccuate.
What mpg have you guys seen??

 

From reading others posts I think most of us are in the 15 mpg range, some a little better some a little worse. One Yellow FX4 that is a lot worse but he must have a problem (hate to make light of your troubles yellow fx4screw). Yours might get a little better as it breaks in too, mine did

 

Bogie,
After 2,500 miles I'm consistently getting 15.5 MPG with a Turbo split exhaust. Tuesday the Airaid intake system arrives, will be interesting to see if it improves the milage.

 

15-16 is about what I get, with the same truck. I have also found the computer to be pretty damn accurate. Generally within a few tenths across an entire tank.
