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...

Absolutely DISAGREE!!!
I towed 20,500# combined with my 98 12V 2500 SRW 4x4 hand calc West Coast toeing 10.5 mpg AVERAGE. The RV was NOT over 12' 6" and was NOT a wide body.
Same roads but 29k combined wide body 13' 2" high towed with 11 HO DRW RAM 4x4 9.5 mpg hand calc.
Same roads 33k combined wide body 13' 5" high towed with current 15 DRW RAM 4x4 9.5 mpg Hand calc.
Same as above double towing at 35k combined 9.0 mpg hand calc.
I say the mileage is MUCH better!
I with Cummins12V98 on this.
Diesel are still delivering 25% better MPG's than any gasser on the market.
Yes the pre Emission diesels trucks may have got better mileage overall than the current generation DEF models.
However the current DEF models are a big improvement over the DPF era diesels when MPG's went down on diesels.
I'm not a big fan of the complexity of the current diesels but the current diesels all deliver lots of power and decent MPG's too.
