Very poor mpg

2017 F350 6.7 is showing 10.8 mpg and that's not towing. What can I do to improve this.

What do you mean “showing”? You mean the GOM? Did you just reset it?

Under what conditions is it showing this???
Truck modded? Bigger tires???
So many things can drag the mileage down.
And, the dash readout is notorious for being way off.
Are you new to this truck???
