I have a new 2015 f250 diesel. I traded in a 2012, my question is my truck shows fuel mileage in the 17's but when I fill the tank it says no higher than low 200's on the distance to empty. Any ideas what may be up?
How many miles on the truck? My low fuel light comes on I believe at 50 miles till empty. When I fill, I usually only fit about 20 gallons in it. It is off by about 50 miles easily on what I have left till I am truly empty.
Do you tow at all? That screws up your DTE when you fluctuate between towing and not towing.
My last tank which was mostly towing set my low fuel light off at 50 miles but I had 1 needles width less then 1/4 of a tank left. My truck was getting 11mpg so it was looking at the past history average and not current driving habits.
Ok. Maybe it is just because it has so few miles. I don't remember what mine did when new but I know now when I fill up it tells me over 800 miles. Oh I have the 50 gallon Titan tank. Last fill up took 43 gallons.
My guess is before you bought it, it idled a bunch from the factory to the dealer. That will kill your mileage and will tank a tank or two to get back to normal. Already sounds like it is returning to what it should be.
