Just curious what others are getting. I'm averaging 10.3 bone stock. I do heavy foot it occasionally.

my last 20k on my Fuelly, I'm averaging 12.7 mpg, with 65% of the miles on the freeway (between 75 and 82 mph for freeway), and probably 30% of those miles towing fairly heavy >14k lbs. I can get 14 or 15 on the freeway if I baby it...its the level kit and 35's that's killing my milage. Non-deleted, been dpf-on tuned 15k of these tracked miles (avg gain +2 mpg). Hand calc, never trust the dash meter...

Good thing diesel is cheap right now, knock on wood......lots of wood knocking..

13-14 mpg with 325/60R20 tires, dual injection pumps bigger turbo etc. My tires really killed the mileage and the dual injection pump and new tuning did to.

after some parts fell off I avg 16.5 with winter fuel driving 60 miles round trip to work. morning drive is mostly highway speeds. drive home is mostly stop and go. little over 60 miles rnd trip.

Drove from northern illinois to gatlinburg a few weeks ago. avg 22 doing 70 mph. got 19.5 doing 80-85 in the mountains.

these are hand calculations. lie-o-meter actually says I do a little worse that the hand calc.

Truck is currently on stock 33s with a 2" block up front and 4" block in the rear.

I know it will go down some when I put 35s on

I stay right around 15.5 with 6'' lift on 37's and a "weight reduction". It'll dip a little when I am pulling my trailer loaded with two four wheelers. I try and be easy on the pedal, but sometimes I have a lead foot :grin::grin:

Around town I'm get a 16.5 mpg average.

On the highway I've averaged as high as 20.

No towing. Hand calculations. MPG readout on the dash is usually about 1 MPG less than what I get doing the calculations myself.

Stock 2016 F-250 4x4 Crew Cab SRW XLT w/ 16,900 miles.
Archoil 6200 at each fill-up

Just returned from an 1400 mile trip through the WV and VA mountains from Ohio to Williamsburg Va. We were running mostly 80+ on the highway with about a 9.5 hr trip time including fuel stops and a 1hr sit down meal at Ruby Tuesdays. The truck got 16 on the way out and 16.5 on the way back. Its a 16 Stock Dually Crew Cab 4x4 with 3.73 gears. The truck gets about 18 to 18.5 at lower speeds on flatter ground.

Stock '16 6.7:

13.6 to 15.4 depending on how I drive that week.


I'm also tracking to see if there is a correlation between my DPF being full or not. It could just be me, but I seem to notice that the truck will be closer to the mid 13's range when the DPF is filled up and closer to 16 after it has done its regen and is closer to empty. Like I said, could just be me though :crazys:

I typically drive at 75 mph on divided hi-ways and 65 mph on smaller roads.
Always use the cruise control.
Stock 20" tires.
Tow some...maybe 4000 miles so far.

I have kept track on every gallon of fuel since day one using the Fuel Monitor app

I have averaged 14.78 MPG (23348 miles using 1579.7 USG).
