Anyone out there towing with one of the new 2008 F250's and the new
6.4 diesel engine ? We purchased one last year and pull a 5th wheel
with it. We've only got a little over 8K miles on her at present. Love the truck, but the mpg is poor, towing and empty. Anyone else
out there familiar with this vehicle ?

Thanks,

I've got the 2008 F250, King Ranch, 4X4, quad cab, and pull a Keystone Challenger 32SAT. Trailer is 10.5 empty and 14.5 fully loaded. Pulled from AZ to WY last year and will do it again in July this year. Plenty of power for most situations and gets through the mountains well. 350hp and 650 ft lbs of torque.

Love the truck hate the mileage. Getting around 12 when not pulling and around 9 when pulling. Been told that there is a computer re-flash coming out in June that may help improve the mileage. I'll definately be looking into that. Haven't had one problem with my truck in 7K miles. Only complaint is the size of the fuel tank, 30 gal. You definately want to upgrade to an inbed tank. I added a 60 gal tank from Northern Tool.

If you read any of the GM or Dodge forums, many there are complaining about mileage as well. In order for the manufacturers to meet the new EPA requirements, they had to put particulate filters in the exhaust systems and they seem to be really causing a lot of the mileage issues. Can't just cut them out or you void the truck warranty.

Next year may be the last year for the Navistar engines in Ford trucks. Ford is developing their own diesel engine that may be in the 2010 models.

Thanks for the response.

I have the XLT, 2 WD version with full cab. My understanding is this 6.4 litre engine is a new engine for Ford, made by International. The first year in production. I'm pulling a 30 ft, 2008 Jayco Super Lite 5th wheel. I love the truck. No complaints, other than fuel milage. Oh !!! It has plenty of power. I'm getting about 15 mpg, when not towing and about 9 mpg while towing.

The last time I took it in for servicing they (about 300 miles back) re-programmed the chip and said I should get better fuel milage now. I've not driven it enough since that time to really be able to tell if it improved or not. The service manager did tell me there were a lot of these trucks getting poor milage. One individual was only getting 7 mpg, not towing. I have a friend who has the 4WD like you. Same engine but extended cab, not the full cab. He is getting 20 - 22 mpg when not towing. I don't understand such a huge difference.

According to the service manager, the "factory rep" says after about 15K miles, milage will become much better. How much better ? He could not tell me.

I'm with you. Why would they ever put a 30 gallon tank on a truck like this ? I liked the old twin tanks I once had on an older F150.

I hope reprogramming the chip works with diesel's prices today.

Thanks again,

The price you pay for having a Ford.<G> I have the Cumins 5.9L HO in a Dodge Ram, with a 3.73. Get 20.4 around town and cross country empty, 12/13 towing 11,070#, calm wind, have to keep looking in rear view mirror to make sure it is still there. <G>
Windage and frontal area has more to do with MPG than any thing else.
If you have a low rearend gear your mpg will be less but windage and grades will effect mpg less than with a high rearend gearing like I have. But with your power you should have higher gear rear end for the F250, allowing a better fuel consumption.
