Im all for better mileage, but 80mph and 20mpg is bull****.
Ill pay for the gas, and if you can get almost 1000 miles (960 on the 48gal tank and 680 on the 34 gal) before needing fuel again at 80 mph, Ill buy you two more tanks.
Im in Houston. Headed to El Paso next weekend, you can tag along.

I think some people expectations are a bit high. These are work trucks. I'm actually impressed that the fuel mileage is as good as it is in most cases. There are full size luxury cars with fuel mileage not much better. I'm a firm believer that fuel economy depends mostly on driving habits. Of course there are other factors such as quality of fuel, altitude, topography and traffic amount others. I've found that 55 to 60 MPH is a good speed to get reasonable fuel economy but an awfully lot of folks seem to always be in a hurry.
My 2017 Super Duty Platinum FX4 gets around 17.3 MPG at 70 MPH and about 18.4 at 58 to 60 MPH.

On a long trip to PA and back, I got consecutive tanks of 22.5 and that's no joke.

I posted facts, some agree and some do not, again I do not give a s***. Look a my past vehicles, number of posts and review my posts. I post and read to learn. I also agree, "Just saying"

Yep, people brag about unrealistic mileage in these and other brand trucks. I got 20mpg downhill both ways to and from school 
Now if you want to know the mileage ratings of these trucks they do have them they just are not published check out what the ratings are for the Chevy, Ram, and Ford trucks.

My truck has averaged 15.5 over its 51K miles.
-Enjoy

I'd love to get 15 mpg with my F450 but I knew when I got it that I would not -- that said I have seen 17 and 18 pulling my 5th wheel; of course going down hill from Raton Pass (I-25) with a tail wind to boot. Otherwise I plan on 9 to 10 pulling, maybe 13 if no wind solo. If the Kansas wind is blowing, knock a mile or two off of both of those.
2017 F450 DRW 4X4 Platinum - Pearl While - what can I say, just can't stop trading up.
2015 F450 DRW 4X4 King Ranch - way more than I need but couldn't pass up the deal
2012 F350 DRW 4X4
2011 F350 DRW 4X2 (discovered I really used the 4-wheel drive more than I remembered.)

Pretty new, see milage in photo. Out driving around, putting 1000 miles on before hooking up trailer. Pleased with stop/go town mileage. Haven't stomped on the throttle yet, max speed in rural area has been 65mph.

My son bought a 2017 6.7 F250 and experienced the SAME mileage drop around 10,000 miles. He was getting 21-22, then drove it home to AZ from his base and it dropped to 12-14. He is REALLY pissed.
I had a customer last week also tell me he had a BIG drop in mileage in his 2017 6.7 - no explanation.
So I THINK this is going to become a popular complaint and I hope it gets explained soon.
