You say in post you are looking at a 7.3 engine, but in title you say 6.7. Which do you want to know about?
 
I have 4 wd dually cc and get 16+ around town, 11 towing 14.5k fiver. On highway see 18-19 depending on speed.

We have a '13 F350, 6.7 PSD, Lariat CC 4x2 DRW with 17K miles so far, pulling a 16.3K 5th and get 12.8 MPG @ 63 MPH but its still in the break-in phase.

Why 63 MPH? Almost all trailer tiresare only rated by mfg to 65 MPH!

Maintain it well, travel safe & enjoy the journey!
 
We tow a 16400 GVWR fiver with a TWD F350 with your 6.7. We consistenty get 11.6-7 MPG at 63 MPH. We have the 6 -spd auto & 373 gears with DRW.

Truck works well, up or downhill, no problems noted over the last 40K miles.
 
My 2011 Ford dually gets similar results to the above. 11.6 towing over fairly level ground, 9 in the mountains, 16.7 general driving, and 20-21 on the interstates when not towing.
 
I have a 6.7, had a 6.4 before that and a 7.3 before that. The only one that gave any decent mileage was the 7.3. Any diesel built after the 2007 model year is equipped with a DPF which pretty much renders if incapable of getting good mileage. (to y'all who are gonna tell me about delete and tune I know all about it)

I suspect most of the numbers above are from the computer readout and I doubt they are pin point accurate. So here is my suggestion to help you enjoy your new 65,000 dollar truck.

Get an auxiliary fuel tank so you don't have to refuel twice daily

When refueling, once the nozzle is in the tank access never never look at the numbers on the pump.

When finished filling both tanks tear off the receipt and never never look at it, just hand it to the book keeper and get in and drive.

Enjoy your truck. Oh yeah, get the 4 wheel drive. It's like insurance, when you need it you really really need it and would pay what it costs in a new York minute.
 
Stanley, Well said. I don't have a computer on my rig (6.7 2014 King Ranch Dually 4x4, 8 ft bed) and get around 9 towing my 43 footer and 13.5 to 14 mpg when not towing. I still love my truck, but don't baby the gas pedal too much.

I never thought for a minute I was getting a fuel saver. But man does it pull sweet.
 
I'm on my second 6.7. Stanley, you are absolutely correct about 4 wheel drive. I'm towing approx 13,000 and get 10-11 towing, 15-16 around town, and 20-21 interstate. I topped off today, and hand calculated at 15.9 around town. But dang does that sucker pull strong.

No way your getting 20-21mpg,I dont get that and I have no dpf or cat.but i do have a cai and tune put in it,6.4 2008.:)
 
Jeff, your challenge to my mpg numbers caused me to go back and read my post again....sure seems to be clear to me. I will assume that you mis-read my post.
Here's my numbers again; Towing I get 10-11 mpg, Not towing I get 15-16 city, and Not towing I get 20-21 highway. Hopefully, this clarification will make you feel better, but these numbers are in fact hand calculated, and correct whether you agree or not.
Happy New Year everyone

yeah right!:d
 
I would suggest you go back to the beginning of this thread. Check the fuel mileage on other 6.7 engines in trucks with single rear wheels. Check other Ford diesel forums. You might learn something. Comparing the 6.7 to the 6.4 is just ignorant. Plus consider driving habits. The fact that you have a tuner suggests to me that you may have a heavy right foot. I'm just an old grandpa, and I drive like one, therefore, I get great fuel mileage. Have a nice day sport.
 
Davidg,
Having had 2 6.4s, and yep, mileage in the 10-11 in town and 13-14 on hiway, with tuner and full delete.
I can only wish for your type mileage, and the money to buy a new '15/'16. Ford has a great engine now, they just need to concentrate on the fuel/water separator situation.
I'm a g-greatgrandpa, don't baby it and love the power. And love the price of diesel.

Hello Joe; Yep, the 6.4 was a better engine than the 6.0, except the fuel mileage was not great. I've been told that once it's been deleted and tuned, the mileage comes up nicely and the power is phenomenal and maybe even better than the 6.7.
I'm very happy with the power and fuel economy of my 6.7. Prior to this F350 with 3.55 axles, I had an F250 with 3.31 axles. When I drove the truck like grandpa, it would return 23 mpg or better, however the towing mileage was about the same.
 
If you are buying a truck and concerned about fuel mileage maybe you don't need a diesel truck. How safely and capable of towing my loads with comfort would be my concern. mpg is just numbers.
 
That's absolutely correct Glenn. I made my choice based on 1. Reliability, 2. Towing ability, and 3. Comfort/features. Notice that MPG is not on that list? Having said that, however, there's no reason that we cannot discuss fuel economy at the same time that we discuss other aspects of our tow rigs. I enjoy most discussions of our fivers and the rigs we tow them with. What I do not care for is being called a liar when I make a statement concerning my rig. I'm to old to be spewing BS. I'm interested in everyone's opinions, and we can disagree on things, but we can still be respectful. Once someone becomes disrespectful, I lose patience quickly.
The previous was not directed at you Glenn....I'm just venting a little. Have a good day.
