My 2010 F450 with 4.30 rear axle never got better then 9.5 mpg hauling my camper. I didn’t do enough driving empty or towing with it to know what that mileage was.

4.88 and the relatively frequent DPF regens the 6.4’s did are mileage killers. Mine never went more than 200 miles and as low as 75 miles between regens. Yours is also a cab and chassis with a GVW of 16.5K, so the ECM will have a different tune than my F450 pickup did.

I learned to hate that engine.

:):)

I went and picked it up today, its a "seasonal" truck. They use it up north to tow a trailcat (small 8000 lb dozer) and bring snowcats in for service.

I went 200 miles on the freeway today without one regen. :B

It used to do it in the middle of climbing steep grades towing the snowcat and drop all the way down to 28 mph. I hated that.

It would drop down to 45 mph on the freeway when it went thru the regen. Is that normal? I hope they fixed that, what a pain.

The did several thousands of dollars in repair in the spring, new regen pump, catalytic converter, 3 sensors and intake gaskets.

The people up north said it ran great all summer. I'm hoping the same thru the winter.
