6.7 Diesel fuel mileage

Looking at a 2019 F-350 with a 6.7 diesel. Currently have a Triton V-10 that gets about 9 mpg. (about 6 mpg towing.) The sticker doesn't list mileage on the diesel. Wondering if the diesel gets better mpg and will it be enough to offset the higher cost of diesel fuel?(3.31 rear end)
Thanks

    My 2011 F-350 consistently got 17 - 19 mpg. My 2016 is getting 13.5 - 14 mph. I have heard that the additional smog devices on the engine has changed the mpg somewhat.

    Diesel prices this time of year in the northeast are typically $1 more per gallon compared to gasoline prices. In the summer, diesel is more closely priced to gasoline.

    There are no additional smog devices, but some things changed in design. I lost some fuel mileage when the dealer updated the programming. I think that the reduction in mileage in the later models is just that.

    Diesel fuel is taxed higher than gas in many states and the amount of tax varies considerably from state to state. Government pretends that they care about fuel efficiency, then discourages it by taxing it at a higher rate..
  • From my experience you will get better mileage but you won't save any money. It works out about the same till you add in the 3 gallon oil changes. What you will do better is pull your trailer. That makes the diesel worth the money.

    In my opinion, the F-350 is the best truck I have ever owned and I have owned all models. The power while towing across this country two times and to and from Alaska is ample. The new engine braking on the 2016 is awesome. Crossing the Rockies several times, I can count on one hand the times I used the brakes to control the vehicle on steep hills. The electronic engine brake and the transmission brake are excellent features on a vehicle.

    Two things I wish Ford would change. #1 The process to re-learn tire pressure sensors is a PITA. Come on Ford. You can do better on this feature. #2 I wish Ford offered 'factory' air bags and inflation systems on their vehicles. Both of my trucks were fitted with aftermarket airbags.

    To the Oper, you won't be sad if you make the plunge and purchase this F-350. As long as it has been maintained properly, it should give you years of service and will be a pleasure to tow with. Your fuel mileage should be better then what you are currently experiencing.

    Good luck and keep us posted.

    I can't believe you asked that question, with all the discussion about diesel mileage on this forum. Our 2016 Ram gets between 16 to 18 in mixed city highway driving.
  • My 2015 F350 Powerstroke gets 10-12 in a hilly town and 17 highway mountain pass. I have yet to pick up my trailer, so can't say that stuff. Towing rates will depend on what you're towing and the slope of the hills.
