Here's a little round trip I made last week..

 

avg speed?

 

Do the math, it's not hard

376.6/7 = 53.8mph average. I got about that at a near 70mph a couple months ago. MPG's are great when the turbos stay quiet

 

I can't drive 55

 

Nice mileage. Best I did on my 2011 4x4 Supercrew Eco was 21.4 on a 240 mile trip over the Appalachian mountains.

 

very nice!

 

I was driving about 62-65 on state and local highways, but I went through a lot of towns, turns, etc. so it takes the average speed down a bit. Used the cruise a lot and did pass some folks getting into the boost little, but didn't drive like an old lady and didn't drive too aggressively. These trucks will get good mpg if yo are not hammering the gas all the time. My truck gets 14 mpg average if I drive it like I stole it, and I mean driving it with some spirit.......

 

Yup, same numbers here a few weeks ago:
