Just picked my 2017 F250 CCLB gas truck yesterday. 257 miles of some big hills, then a little city driving and then rural and country driving. Gauge shows 15.4 MPG. Happy as a Pig in Poop.

I enjoy reading these results / reports........ But
in my experience without stating cab/bed configuration, axle ratio, Tire size etc the information is to some degree meaningless.
The 3.73 axles will yield different results than 4.3. A regular cab short bed different from a crew long bed. A stock 17" Tire much different from 35"-37" that can weigh 50% or more above stock tire.
There is enough difference in the the weight / force imposed by our feet alone..... At least having a few spec details helps to normalize the info...... For me anyway.
I have every tank of gas for the past 10 years hand calculated in spreadsheet. I also have the instrument panel reading. Over the long haul they can be relatively close but I see as much as 20% or so difference on some fill ups. This can be caused by the level of the truck when filling, the electronic estimates may not be as accurate as we think / hope, etc etc. etc. So I find having both data to have some value.
Regardless, I have clear measurements confirming MPG changes just with tire size/weight, driving habits, etc.
In addition, the past 6-8 tanks I have been diligently forcing myself to accelerate slow, Coast, avoid stops where possible and drive slower in an attempt to maximize MPG. The improvement is amazing as I am averaging about 2 MPG better.
In all of the above I am talking about my 2006 F150 SC Lariat 5.4L 4WD with 3.73 axle running 275x70R18 Duratracs. It's been amazing to see what I can do with MPGs with some simple foot restraint.
The order for my 2017 F250 CCSB Lariat FX4 6.2L with 4.3 just went in this week. So reading here and several of the past threads on 6.2L MPG helped me make my decision to go F250, 6.2L, and 4.30. It appears that I will have much more truck, much more / newer technology and be able to maintain the same or better MPG as I have the past 10 years.
In a few months I will be able to add some useful data here. Thanks to everyone for their input!

Mine seems to be improving. I reset Trip 2 every time I fill up to get some idea. I will also say the truck calculated MPG has always been about .3-.5 MPG higher than hand calculated. I did a small 1 hour run last week for some alfalfa and pulling a 14' utility trailer with about 1K - total load about 2k, I was getting over 14 on the way home. These were country back roads. I was a little surprised. I know highway empty I can get from 14-19 depending on speed. I am approaching 9K miles currently.

250 Lariat CC 160" FX4 with 275/70/18 Tires. My commute is 13 miles each way to work, almost all highway. The worst mileage I have seen is 10.2 at fill-up, the best is 11.7....I have not taken a long distance highway trip with the truck yet.

Hey fishrprice - would you mind sharing what your payload number is on your door sticker? I am going to be ordering a 250 XLT Value CCLB 4X4 here soon and it looks like you have the same configuration. Do you have the 4.3 or 3.73 rear end? I'm leaning towards the 4.3. Thanks!

1450 miles getting overall 14.5 mpg. I have a 373 rear end. I live in a rural area and drive mostly two lane black top country roads. Yesterday I drove 110 miles round trip from my workplace to Milwaukee and back to pick up an 800 lb pallet. On that trip average speed was 55-60 mph and milage was 16.4 mpg.
