Im thinking of buying a 6.7 F250 Diesel. Please tell me your true fuel milage on the Factory 6.7 without add on upgrades.
Id like to know everyday milage without pulling a load.
the most Ill ever pull is 5,000 lbs.

Take a look here:

You can filter by engine type. That’s about as accurate an estimate as you will see on the internet. There will be plenty of folks tell you their 3/4 ton gets 25 MPG, but that don’t make it true.

I have 37 of them running in my fleet right now, all the guys that got them immediately noticed that they got better fuel mileage over their 2018’s. They are reporting 18-21 on average.

Why get a 2500 if all you're pulling is 5000 pounds?

The extra fuel and the higher buy-in and insurance doesn't justify.

5K is less than half the capability of a properly equipped half ton.

^^^^^^^^
This

Yup, my 2016 ram v8 is still averaging over 20 mpg and it’s got over 100k miles.

Those 10 speed transmissions help quite a bit

Yeah, too bad they dont help the looks of that front grill.

A face only a momma could love
