I have the 5.4, 3.55, 4x2 Supercrew. I have kept records since buying the truck. Every fill-up and all mileage. I drive to get there, not conservativly, and every now and then I get on it pretty hard. On the highway, I drive 75 to 80. Mixed driving with more highway driving, I get 18, mixed with more city driving, I get 16.4. My total miles driven, which is over 10,000, I get 16.75. Most of my driving has been in and around the city. Hope this helps.

 

I'm getting about the same as everyone else on here....11-14.5 city and 17-19 hiway. I find myself punching the reset button for mpg just to see it jump up to 35-40 then fall rather quickly back down to 12. Dang, I can dream can't I?

 

Just took 2 trips from Memphis to Little Rock this week.

First trip I drove 75 to 85 there and back.I got 16mpg with AC on.

Second trip I drove the speed limit, mostly 70 and got 20.4mpg with AC on

Like chasman said,these trucks can take sips if you take it easy.
