I don't know how you are getting that MPG. I have 8500 miles and am getting around 10MPG in town 5-7MPG Towing. Wish I got 17 MPG! How can the MPG vary so much on all these 08's?????????

You have to compare apples to apples. Someone who has a f250 with 3.73's and drives it at 60mph is not going to get the same milage as someone who has a f350 with 4.30's and drives it at 75mph. Its a truck did you buy it to haul or to complain about mileage? I bought mine to tow my trailer when required that and I love the fit and finish. It is a mans truck. Like my 4 year old daughter says suck it up princess. I agree that there may be differences in mileage but compare correctly don't just complain about the MPG. All the details are required.

 

are flashed free from the Dealer? what gears do you have? my 4.10 gears get exactly 12.4

 

You got all that right.

 

yes they are free, usually if you have your truck in for an oil change or other issues they will update the truck computer. Mine is running great, I do not want to have it flashed at this time. For being new 12.4 is pretty good depending on how you drive.

 

It would be interesting to see a computer log of what they are actually changing when ever the reflash the PCM.

 

That would be interesting to see if it was in English

 

When I first got my truck, it was running in the 8 MPG range empty. That has gradually increased to around 11 MPG empty. If I really baby it, (never go over 60 MPH and never let the boost exceed 20 lbs.) I can get a little over 12 MPG.

Now comes the good part. I bought the truck to pull. I pull stock trailers, horse trailers, and a 34' fiver. My fiver scales out at a pretty even 10,000 lbs, and pulling that trailer hard, I've never seen less than 8 MPG, averaging around 9-10. That's the beauty of the 4.30 rear end. It hurts the mileage empty, but you can get netter mileage loaded.

If you bought this truck to drive to the grocery store, you may not be happy. But if you bought it to do what it was made for, there's not a better choice on the planet.

 

I agree with you 100%. This truck is a worker. I have the same truck, short bed. I have only 1300 miles on it, but am averaging 11 MPG except on the interstate in cruise at 65MPH I am at 17.5-18.5 empty. If I am towing the TT, at 10,000 I am at 9.5 to 11.

I love everything about the truck. It is an absolute dream to pull with. It sure gets a lot of attention at the campgrounds!

 

what do you have? can someone tell me where to fill out our signatures, they say it's in UCP but I can't find it.

 

I have a 08 F-350 6.4 SD, 4x4 shortbed crew cab.............Don't know about the signature thing.

 

350 4 x 4 SRW? what rearend gears?

 

3.73 rearend

 

Guy's:

I haven't got my 450 as of yet (by Oct.11), I have a question about the 6.4. In the Ford sales literature, in small print at the bottom of the page, it says "the 6.4 is detuned for 6speed and 4:88 geared trucks". Why are they doing that ? I'm getting the Auto w/4:30's. Is that why the MPG is not so good ?

 

I know I love mine!!
