2016/2017 F250 6.2 Gasser MPG

2016 F250 6.2 with 4.30 gears. I average 12-14 non towing, 9 towing the fifth wheel.
The wife gets 10. She can't keep her foot out of it. Says she loves the Growl. Great engine - get the 5 star tune

I have a 2017, 4x4 with the 3.73 rear end. Right now I'm seeing 13.5 on the screen with half tank running about 100 miles highway, 50 miles around town. ATM I have 600 miles on the truck. When running the highway I usually am running 70-80 mph. Can't complain considering my 04 f150 2wd with the 5.4 and 3.55 axle got about 14-14.5 with the same style driving. I expect that number to increase a little after some more miles get on the truck. From what I was reading the 4.30 rear axle isn't much worse on mileage, maybe a little better around town since the lower gears help with low speed accel. I had planned to order the 4.30 but found a great deal on the dealer lot.

Buddy at work just bought a 2017 f350 with the 6.2 and is really happy and surprised with the mileage.

My 2012 I had "averaged" 12.5-13 with 3:73's. The new ones "2017" are supposed to do better now that they have a trans specifically for the gas 6.2 and tuned for it. Plus they are awesome looking trucks! If you are serious about it, Id order one with the 4:30 rear end though. Everything I read says this is a better ratio for the 6.2 and really brings out its full potential. Only thing that suffers is highway mileage which only drops 1-2 mpg, but daily round town mileage actually improves some as the truck isn't lugging as much. Again, only what I've read though. Let us know what you decide! I love new trucks! Lol

Mine 8.5 towing a 25' Work and Play @ 65 mph from Jacksonville, Fl to Charleston SC. It gets about 12-12.5 non towing on the same trip but at 75 mph.

My 2016 gets 16 highway, 11.5 regular driving and 8.5 towing.

My 13 will average 16 on the hi-way at 65-70. Not bad in town with light foot, maybe 13, towing my rig 8-10 with varying terrain/wind.

According to Fuelly, you should expect somewhere between 11 - 12 MPG.

10.5 day in and day out in the city. 15 on the highway at 70 if I'm gentle with it.
