I'm getting 20 highway with my ip all the way up on my 6.9 and i have 4.10 gears with a 4 speed tranny

 

[GOOSE]

Around town always got 14-15 with the logger. My only true highway run got me 357 miles out of 18 gal on the front tank. 19.83 mpg. I am quite happy with that out of a 7400lb 4x4 with 4:10 rears.

single cab 250 in my sig gets 18-19 if i take it easy on her on the highway got it up to 23 one time but that was about 10-11 hours straight of driving 55 on flat road. normal mixed driving yeilds about 14-15 with the 285 tires on the back, only ran two fillups since I went to 265s on the rear but both have been high 16s. buddy of mine used to get 24 out of his 6.9 c6 3.55 250 but that was his math which meant he added about 2 gallons of different additives and then calculated fuel mileage on how much diesel he had to add after the additives.(same guy averaged 32 out of a late model 12 valve and 26 out of a psd) Guess math wasnt his strong suit

Loaded, empty, highway or city...I get 14MPG imperial....That's it........Grossing a little over 8000lbs empty, 4.10 gears....Reman injectors and IP...Truck runs like new but it doesn't get much for mileage....Makes it easy to price jobs...

don't beat yourself up over the 20 mpg comments when you see;
4.10's/dually/direct driven trans.

he may be unaware that his odo is off.

Thats what Im thinking. I did lost of driving and lots of long distance driving and only went over 60 when I had to and rarely saw just a touch over 11. I drove from Tampa Fl. to Muskegon Mi. and the best I got was 12. in Kentucky when I never went over 55.

 

[Sycostang67]

My 86(OEM tire size) gets 20 as long as I avoid the freeway. It has the original IP/injectors with 193k. My 93(285's) gets around 15 under normal driving, gotten as good as 18 while babying it.

 

[pt_Ranger_v8]

I get roughly 15-17, mostly city driving.

7.3 NA, ZF-5, 3.55's, no front driveshaft, and a 4" lift.

 

[Jbevs]

What size tires you runnin pt ranger?

 

[Goofyexponent]

That's about right on par with what I turned out for numbers on my last fill up.

16 US gallons got me 302 miles which is roughly 18.9 MPG.

For the other Canucks on here......60.6 liters to go 487 kilometers gives me about 8.03 kilometers per liter....or 22.5 MPG imperial.

This is on 265/75R16 rubber, 3.55's a ZF, non turbo engine and the pump is turned up LOTS..I rolled coal on more than one occasion to remove the tailgaters but for the most part I took it easy.
