2012 F350 SRW 4X4 w/3.31 rear axle:
Overall lifetime average MPG - 15.7 MPG (hand calculated total miles/total gallons)
Towing heavy (14K lbs) - 9-11 MPG
Highway empty - 17-18 MPG
One thing I've noticed is that this engine seems to be a pig during warm up cycles. If you do a lot of short trips, your mileage will suffer. You'll also go through more regens, which also affects mileage.

Just recorded my best ever fuel mileage at 16.2 including a couple of regens in there.
Towing heavy (over 18k Fiver), I was between 7.2 & 8.2... A stock 7.3 would have a heckuva time trying to drag my camper up a steep hill, but this 6.7 just walks up the hills on cruise control without breaking a sweat...
This is a 9k truck and I'm pretty happy with it...

Exactly how I see it. I can average 19 hwy empty and 11-12 towing my 5th wheel. Coming from a 7.3 performance tuned and cat delete 97 F350 to a 2012 6.7 stock is a huge difference, most noted in fuel mileage and power performance for towing.
