anyone with the new body style 6.0 / 6 speed , what are you getting for milage ?

Have had my NBS GMC 2 weeks first fill 13.1 2nd fill 13.4
filled again yesterday drove 20 miles home the DIC was telling me 18.0
pulled my 2 place snowmobile trailer 50 miles and the DIC showed 9.5
reset it this morn and drove 20 miles and it is now on 15.5 mpg
have 760 miles on it
traded in an 05 duramax that got 16 driving to work
so far i am very happy with the 6.0

I talked to a guy the other day that had a nbs with the 6.0 and auto and he said he was averaging about 16 with mixed driving. Truck was a reg cab 4x4 and he said it had 3.73 gears in it.

Mine is at 14 .5 with 750 miles on it. extended cab 3:73 gears

Mine is not much better 1300 miles and range from 12.5 to 14.5 MPG.

those with a decent amount of miles yet ? what are you getting with it broke in ?

Mine is not much better 1300 miles and range from 12.5 to 14.5 MPG.

1500 miles on mine & about the same...will be taking the TT out in about 3 weeks for the first time with the new truck, will be interesting to see how different it will be from my 05 LLY...

You guys must have a very light right foot. I'm getting between 10.5 - 13.5 mpg. I've got about 3500 miles on mine right now. I drive about 90 miles a day and 95% of that is freeway miles. I do drive between 75 - 80 mph. I know that doesn't exactly help my mileage, but it shouldn't be that bad.

I have 4,000 miles on mine and 4.10s.
I get 10-13 in town(my wife can get 13)
on the highway my best was 15.5
Towing my 30' 5th wheel I get 6-8.
