How many mpg's are u guys getting in 5.4 superduty

I just wanna know u read on here what everybody get's and i just find it hard to beleive.I have a 05 f250 Crew Cab 4x4 with 3.73 rearend with 122,000 on it.I know miles might have alittle to do with it but i get 10.7 mpg on the highway.The truck runs great no oil burning everything is fine with it how am i getting that when people say they 15 to 16 i just don't understand it.Mine is all stock no tuner or exhaust nothing stock tires everything i just can't see people getting that without being in a 150 or something.Riddle me that one batman.lol.

I hear you... I bought my truck expecting about the same. I'm running basically the same truck except an '02. The best I have ever gotten on a long highway trip was 12 MPG but its usually 10.5-11 at best.

My '01 F250 4x4 averages about 12.4 MPG, I check it every tank fill. It has NEVER gotten below 12, and NEVER gotten as high as 13. Bizarrely even mileage, never towed with it, but I do run a plow in the winter for a couple hours a storm.

Wow, just wow.
You guys need to look at your fuel sources, condition of the engine, tuneup, etc..something's definitely not right.
What you guys are talking about for fuel economy, is what my V10 F250 and V10 Excursion get regularly.
