2012 F 250 one year later

[Buppies]

Truck was out in snow today and overall performed very well. Engagement was very smooth no clunking or clanging. Locking rear diff. also easy to use but slower to disengage . Nav system is sometimes confusing to use but hooking I phone to radio is a breeze and having music of my choosing is great. Today's snow was only about 2in deep so not great test but weekend looks to have 6 to 8 in. Lots of things in center display to look at but most will never use. Still don't totally understand my key properties.

I've got a 2012 f-250 Diesel, with 12,000 miles on it. Why in **** am i only averaging 15.6 ?? Usually when i feel up the trip/mgp underestimates my fuel use by .5 - .75 gallons.. so its really less than that!

What R/end gear ratio do you have ? Did you get notice from Ford to return truck to dealer to have it checked or reprogramed ?
Have you reset your MPG indicator manually and see if its still saying same along with paper fiques ?
Just some thoughts.

As Bullbreaker mentioned, what rear end do you have in the truck? I have the 3.55 electric locker in mine. Also, how do you drive yours? I drive mine on the conservative side just for the fuel economy aspect. My MPG trends down when the thermometer drops below about 25 F. There are a lot of factors that contribute to MPG, but 15 MPG or less is something I have never experienced without towing a heavy load.

I have the 3.31 rear end. I drive 15 mins to work every morning at 70mph.

Then drive about 35 miles in afternoon, average 55-60 mph.

Have not had it reprogrammed.

Most every time I fill up my trip says 20.8 gallons used, but tank accepts 21.8.

Avg mph is 15.6. But when you factor in it being overly optimistic on gallons used, paper way it's more like 14.5...
