I've got about 6500 miles on my 08 2500hd with 3.73's and the auto, on the highway (30 miles one way a day to work and back) with a little around town driving I'm averaging about 18 hand calculated, 18.8 to 19 on the overhead, and that's keeping it at about 70.
I push it to 75 to 80 and it goes down into the 17's. I haven't touched a thing on the truck yet other then changing the oil once @ 5000 miles. I'm pretty happy with it.
