Agreed.. I`ve driven a few 09 dmax`s and didn`t see over 15-16mpg on the highway. Not real impressed with the new ones mileage. : I`ve heard GM`s doing away with the 6.0... but what does that mean for the 2500`s... does that mean they are going to put the 6.2`s in the 2500`s?

Thanks for the info. I drove both at a dealer last night and he was claiming the new 6.0 with the 6-speed would get 18 or better on the Hwy. I`m skeptical... I like the power of the Diesel and if it gets better mileage, also a plus. I`d like to figure out what people are getting with the 6.0L 6-speed in the real world.

I just traded my 02 2500HD with the 6.0 & 411 rear end in for a 09 2500HD with the 6.0 373 rear end 6 speed trans. I got 13 hwy 10 city with the 02 (good truck over 200,000 hard miles) granted the 09 is new has less than 2,000 miles on it now but getting worse milage on the hwy and city. Hope its gets better with age. 6 speed trans has a lower gear (granny gear) and a higher gear (real weak any small hill trans kicks to lower gear) the...

I had an 07.5 Dmax and I could never get better than 15-17 MPG no matter how much I babied the truck. The DPF system in the truck ate fuel and took away a lot of the power I had enjoyed with my LBZ Dmax. My LBZ got about 17-19 no matter how I ran it and I got rid of the Dmax and found me a six speed manual 6.7L Dodge Ram which gets right at 18 MPG. When fuel is a dollar more on the gallon than gas I would suggest the gasoline in the 2500...

I`ve also heard they are going to start using 4.5L Dmax`s instead of a 6.6 something to do with emissions...Proly twin turbo to make up for the 2.1L that is missing from the old one ( just my theory )
