Looking for 2010/11 F350 MPG

[meterguru]

I have a 2008 F350 Dually. Was a shock changing from my F250, it was getting 13/14 towing and 17 around town. Now only get 8 towing and 11 around town. Part of that was the axle ratio changed from 3:73 to 4:11. Looking to replace with a new 2012 F350 Dually with the new Ford diesel. I heard a few good reports so far but looking for real time MPG. I'm looking at the F350 Dually with the 3:73 axle. My trailer is about 14500 lbs. Fifth wheel.

Just about any of the big 3 with a Diesel will get around 10 to 11 pulling that weight, that's if the people are truthful. I have the 2011 Chevy 3500 Dually, Truck is 9100 Lbs, 5er 14,100 Lbs. Cruise around 64/65 (so I can get into 6th gear) average right around 10.5, some less, some higher all depending on weather, wind, grades, and biggest factor: quality of fuel. Some fuel really sucks, prefer to run Premium Diesel but not generally easy to find.

What is premium diesel? Have allways used #2 and if really cold #1 never have seen Premium...

Premium Diesel has a little higher Cetane count, cost a penny or two more than reg Diesel, but is better for many of the Newer Pick-ups. I get better mileage when using it, but it can't be found in all places. KwikFill in Western PA, Western NY, and Eastern OH carries it.

I just bought a Dodge dually (see sig below). I've only done one trip so far. I got 11 - 12 MPG towing on relatively flat highways. I'm getting 14 city/highway combined. My GCVW is 20,000lbs. I only have about 1000 miles on the truck so far and I understand that MPG will get better with more use.

My hope is that the new truck will get at least 14/15 MPG not towing and if I get 10/11 towing the savings will add up quick over the present 7/8. Dealer says I should see 14 or so and was just looking for some verification. With these facts I believe that it will be worth the purchase of the new truck.

I have a F350 Lariat dually 6.7 and drive 12.9 miles one way to work. 9.4 on interstate and the rest from 25 mph to 45 mph. I average about 14.2-14.8 (hand calc ~20 gallons each time).
Pulling 14k (loaded) 5er ~ 10-10.5.
