You hear all these people claiming 20 or more out of their diesels. I don't expect that. Just something decent.
Fuelly - Track and Compare your MPG Statistics shows the 2015 gets 2% lower mileage on average.

Have had both setups. Blew my 2013's turbo up so I upgraded to a 2017+ retrofit turbo kit plus a 2015+ HPFP. No questions asked, the 2015 setup is a better truck in every way. Better mileage, better power, better driving experience overall. The ONLY downside is the turbo doesn't spool up quite as fast but it just pulls my boat so much easier than the 2013 setup.

Any questions, feel free to ask!

2% MPG difference...LOL...not to mention how people refuel (ie filling to the cap or stopping at the first click off) will vary across the board.


But you know the Fuelly App is the God's word for fuel usage......That's sarcasm by the way.


All you really did was demonstrate that the two configurations are soooooo DAMN close to one another to show your claim of:

15 uses more fuel by design.
doesn't really hold any water.

I have a 2015 dually has the FX4 ultimate package and it stays in the 9-10 range with fuel. Oh wait, yea thatís probably my heavy foot. I just love when the dodges and Chevys try and keep up with me when Iíve got a normal load on (20-27K lbs). My brother in law even said the new fords are the better trucks hands down. Heís driven dodge all his life and just recently bought a brand new High Sierra dually.

Haha! Thanks guys, all good info!
Isn't there something also with the 2015 that a few of them had issues when they changed the fuel delivery system?? Seems like I have read that somewhere before in this forum but not sure where. Maybe just a few in a certain VIN range or something.

How on earth did you get such low mpg? I have a 2011 F350 lariat and i could mat the thing all around town and get those numbers. I drive about 50/50 highway (60mph) and city (45mph or lower) and get 19-21 in the summer depending on idle time, and 16-18 in the winter also depending HEAVILY on idle time lol I like to let it warm to 100 on oil temp. Even my old 7.3L got better than the numbers you got using real gallons in to miles driven the 7.3L got 16-17 mpg with the 525 ft/lbs. motor.

My mileage in the '16 isn't that good either.

The "lie-o-meter" averages it out and I get anywhere from 12 to 15 MPG depending on how much I press on the fun pedal

My dash says i get 11-13. city driving. It got worse after i deleted a tad. I don't really care though. I don't put a ton of miles on. 15-16s get a tad worse fuel milage it seems due to the increased power.

I've got a 14 dually 2WD with 3.73 gears. With mostly city I get 14 mpg. It jumps to 17-18 on the highway running 70 mph.
