They should.

Lots of folks with those new Powerstroke Super Duties are getting 8-10 mpg.

I don't care how good of an engine it is, no one can afford that for a work vehicle.
And my buds new duramax does 8 - 10. That has less to do with Ford and more to do with the new emmisions on ALL three of the brands. Thats why my buds are selling thier 08's and buying older versions that did much better re MPG no matter what the brand.

Trucks in that class are not rated for mpg.
Anybody know what they would be if they did, not testimonials from fan boys in either camp, but factual? Is there factual? I seem to recall someone telling me their truck got over 20mpg when they added a chip.

Maybe with a DPF delete and chip.

By law they don't have to be, but don't think it doesn't play a role in consumer interest.

The truth is, all three of the big 3 diesel's have been hurt fuel mileage wise by the DPF. I mean, during a regen, fuel is added to heat up the regen process to burn off DPF pluggage. Obviously then, fuel mileage is going to suffer.
