LOL I'm jealous, but then my F450 has 4:77 gears so fuel mileage sucks. and I always have my 52 ft gooseneck on the back loaded most of the time...If I could see 10mpg just once I'ld be tickled pink

I left MIAMI on a full tank & drove to ORLANDO, FLORIDA, while spending the week there & driving thur traffic, i was able to drive to WEST PALM BEACH before fueling up again, I didn't reach the low fuel warning on my truck, i drove 625 miles & average 18.66 MPG

I got 15.96 mpg out of this tank full

Only got 14.06 MPG out of this tank full, it's the terrible bumper-to-bumper traffic, & when there's some open road i smash the skinny pedal

only got 13.87 mpg this tank full

My 2013 F-250 6.7 with 3.55 gears only gives me 13.9 MPG, but i have a heavy foot, would like at least 16 mpg, but i doubt I'll ever see that
