If you drive east coast to west coast then last week you had plenty of wind. Also you’re getting winter blend fuel at many places now. But you could also be starving your truck for air. How long has it been since you’ve replaced the air filter? How long has it been since you’ve tested the charge air cooler for leaks?
Poor fuel mileage

#4 but in neutral, Georgia overdrive? -
This time of year gets windy and cooler air has higher density , causing more resistance drag, so more energy/ fuel is needed to push the truck through.

My thoughts, exactly. First thing that came to mind was the change in fuel blends to winter.

Could be a lot of stuff......dpf could be getting clogged, could be bad fuel injectors, how old is the truck?

Check air filter and charge air cooler.
My best month is normally July or August. Lowest is normally Jan, February. I have seen 3 mpg difference with everything functioning properly.Brettj3876, '88K100, Newbieboy and 1 other person Thank this. -
Kerosene mixed with diesel will hurt your MPG.
