2008 F250 6.4 7.6 MPG when towing?

- Start date
I get 13 mpg with 3:73 gearing in tow/haul mode at 60 mph with what you see hear in the pick loaded up with all our gear needed for a get away. BTW, the truck is stock other than a K&N air filter. This mileage calculation also includes warm up time.
08 6.4L F350 crew long box w/27' enclosed charmac and 4 sleds 8.5-9 mpg doing 75-80mph. I used to get 13-14 w/my 06 5.9L cummins. The emissions crap (dpf) sucks! I do love the truck though, just not the mileage! Average around 13mpg in town and 15mpg on highway.
I've had 3 vehicles with a display and they were all off!! Checked at the pump is the only accurate way. Pisses me off when guys report of high mileage and they're going by the display!
I had a 01 7.3 and now have a 04 6.0. Seem fairly close in mileage, 15 +\- empty and 12 on down loaded. So many factors involved- wind, #1 fuel, terrain and mostly(this one kills mine) speed. A friend of mine gets great #'s whatever he drives cause he drives like a grandma. Hate riding with him cause it takes forever to get somewhere.
I was just taking to a guy that had a 05 duramax and now has a new one. He said mileage definetly went down the crapper, wishes he had the 05 back.

Learned something interesting today my 6.4L F250 will get almost 9mpg at 97mph empty.
funny my buds new f350 did the same, got better mileage runnin against the gov pullin a four place than at speed limit??
I have a 2006 f350 cc longbox 3:73 pulling 6place open i get 10 at 78
But it is in the shop getting new turbo, headbolts, egr cooler, and headgaskets.
So we took my buddies 08 6.4 same load running 78-80 6mpg
So what you save in fuel you spend on repairs.
Got to love these ovals.

Your mileage will go up about 4mpg once you hit 50,000 miles
I have a 2000 F250 CC 7.3. The best milage at 65 has been about 16 and it loses about 5 mpg if pulling something. Have about 130,000 miles on it and never saw the improved mileage that everyone said I would get after 20,000 miles or so! However, it has been a very dependable truck, just don't like the fuel economy. And don't trust the computer on the Lariat because it is always about 4-5 mpg off! Also, I put an economy chip in it after about 5,000 miles and never say much if any difference, except the transmission shifted smoother.
I'm getting 10 mpg towing 27' Interstate enclosed trailer and 15 mpg running empty @ 80
Just thought I'd put an update on this. My pickup now has 5500 miles and the temperatures here have finally gotten above 40farh. Not sure if its the temp or the miles but my mileage has gotten a bit better. My last trip with 90miles of interstate at 75, 40 miles of 65, and some in town driving hand calculated came to 15.2mpg. Pulled home a 12" PTO driven pump with a 20ft cast iron pipe that weighed about 6k with the trailer at 78 and was still getting 12.5mpg temps were in the 20s. I should add I have the 3.55 gears which still seems to be no problem with power of the 6.4L. Oh I should add I was a bit off on the weight of our skidsteer is actually 7k#s instead of 5k#s.
Ya ya, Lets bring this thread back!
Just got back from out west and pulling our 4 place enclosed with 4 guys and 4 sleds plus all riding gear at 75mph I got 8-9 mpg avg. over all both ways.
I cant wait till my 05 GMC dura gets broke in and I start seen 15 mpg pulling! They say the next 100k will be the best!

Jdracer, are you getting headstuds, and an egr delete while its apart? Well worth the small fee (in the diesel world) to have that done. Would give you less complaints in the long run with your "oval".
Lol, F450 weighing in at around 8600+/- pounds, 4.30 or 4.88 gears with a stock sized tire, 14-15mpg would be awesome to get.
doing 60 might help your mileage.
People lie.
