GeoBoy,
Your mileage figures are quite impressive. How did you calculate them, by hand or by using the trucks on-board computer?
I currently carry my 811 on a Chevy 2500 HD with the Duramax and although my mileage figures are 2-3 mpg better, I'm considering going to a new 3500HD 6.0 gasser.
What axle ratio do you have? Inquiring minds have a need to know......
I checked your profile and see that that you have 4:10 gearing.
Thanks,
TG
Ray, my mileage is hand calculated, I use mid-grade gasoline and I keep my speed under 65 mph. Did you buy your AF from Niemeyer's?
I get:
12mpg empty
8.5mpg with the TC
Speeds under 65mph.
2015 3500HD 6.0L gas, SRW.
I wish I could figure out how you guys get that spectacular mileage.
For comparison, I got 21-22mpg with a 2014 5.3L 1500, driving it in the same places.
This is hand calculated mileage.
