Right down awesome.
I don't get near that on my 5L

 

I do.

I press reset, let off the gas and get 50+ mpg, then snap a picture!

 

250 miles. Max 70 mph on cruise. Ended the run at 25.8 avg. I think it would be 26+ if my wife hadn't needed to pee. Women!

 

Never ever seen mine do that, except how 06yz250f said. Then again FX4, 3:73, 20's, & crew cab don't help the matter

 

i am getting 14/19 with my 5.0 it was a Little better but it has drooped thanks to winter blend!

 

Yeah, I wish I had some flat highway to do that on ... my usual road trips take me up the PA turnpike and its mountains. Going through the mountains at 65-75 mph, I usually get about 20 mpg on the way up and 21 coming home. Averaged about that yesterday, even with the crawling traffic. Love my EcoBoost!

DDrummer.

What type of truck cab, engine, 4x?, and axle ratio do you have? I am curious to know...thanks

 

Best Ive seen in my 2011 5.0 Screw, 4x4, long box with 3.73s was 23.2 on the hwy.

 

Austin,

I have a SuperCrew 3.5L V6 Ecoboost 4x2 XLT. My axle is 3.15

The trip was from Atlanta to south Ga. 4.5 hrs. First 3 hrs was interstate with the remaining 1.5hrs on state divided hwy and two lane roads.

I ended the trip at 25.8mpg which is about where I was at when my wife made me stop on the interstate.

 

Wow, the 3.15 rear axle sure makes a difference. Best I can muster out of my F150 is 23mpg, 24 if the wind is blowing the right direction. I have the 3.55 locker.
