Ok. So guys with either of those what kind of mpg are y'all seeing and what if anything have y'all done to increase? I'm possibly going to make the purchase and I'm just curious.

6.7 -
18 Highway

Check out fuelly.com as well. There may be some owners who have logged their mileage.

I'd like to help more but my Chevy is a 2016 so completely different motor besides displacement size.

My 16 F250 6.7L got 15.8 on the way home saturday from my lease in San Saba (highway). My speedo didn't go below 80 for probably 95% of the trip.

Same with my '16 gasser

How do you like your '17 Duramax?

My f-250 with a 4 1/2 inch lift gets 17.5 hwy and 15 city with my Stealth unit installed. When it was stock I was getting 23 hwy and 18 city

I love it so far. I came out of a '15 F250. Was really torn on buying it and a '17 F250. In all honesty, it rides better, drives better, and the engine has more power. I towed with it a few weeks ago for the first time and it didn't even blink. I make drives between Midland and Houston or Fort Worth all the time and the biggest thing I've noticed is I don't feel like I got beat up when I get there vs how I felt in my F250. Highly recommend it.
