Tuesday i filled the truck up and we (wife and 3 kids with a smaller cooler and few bags so not too much weight), jumped on NYS thruway north for 2.5 hrs to an amusement park, 6hrs there and then 2.5 hrs home with cruise set at 70-73 (troopers every few miles it seemed like) the whole trip there and back and best was 17.8....View attachment 180200
It went to 17.8 right before we got off the thruway...
Fyi and btw......this was with my range unplugged. we are going to do the same exact trip either next week or soon and i will plug the range in and see the difference.....stay tuned...... to be continued.....on our next episode.....etc, etc, etc....

Did you reset the average MPG gauge when you filled up before the trip? Otherwise, it's including the MPG from all the driving since the last time it was reset.

I reset mine every fill up as well. Not sure how else to get an accurate mpg count besides the dic.
It is in the glove box. My RPO code is GU6 so I have 3.42. I used to have a Tahoe that had 3.08 and that thing was a dog. I had to mash the gas everywhere and gas mileage suffered.

If all your driving is the same, then it's not gonna change much. But, if you reset it before a trip, you'll see what MPG you're averaging just on that trip. I never thought about this until I had an '02 Grand Cherokee with the 4.0. It seemed to stay stuck around 17.5 MPG. I was messing with the menu on the overhead display one day before a trip and reset the MPG thing. A couple hours into the trip, I was pushing 20 MPG as if I suddenly found a way to increase the fuel economy by 3 MPG! Those few hours of highway cruising isn't enough to raise your overall average MPG much when it includes the months of city driving into the averaging.

Away!
Depends on how you define good. It's pretty nice if you're cruising on the highway. Around town, it's a bit of a dog, but not horrible. I liked my 3.73 better overall. Wheel /tire size play a large role here, too. The bigger you go on the 3.42, the more you'll notice it being sluggish.
With the 6 speed transmission It is "supposed" to be the same as 4.10. The only way to get better gearing is the 2500 6.0 or put it in yourself. I have heard of people having 3.73 with the 6 speed but I have not seen it.

You could do it the old school way: Reset the trip odometer when you fill up then divide the number of miles it reads by the number of gallons it takes to fill up again. I used to do this religiously with my S10. I'd fill up at the same pump and let it go until the pump clicked off instead of clicking it off a few times because that would skew the numbers with more variables. I calculated it myself a few times when I first got my Tahoe but quit when I found the DIC info to be close enough to my calculations.
I still do this with my 02 suburban and my wife's 2010 Yukon XL Denali. I have averaged 13.5 over 50k with some towing our 6500# camper and 2 winters in upstate New York with horrible winter gas with the denali.

I would LOVE to have a 6-speed. After having 6-speed transmissions in my work vans, I HATE having only 4. It's either lugging or tach'ed out. Mine has the 3.73, I don't even wanna try to imagine it with a 3.42.

New weatherstripping on driver front door. Last one to do is the passenger front then maybe the rear liftgate.

Oil change while on the clock. Got to love it.
Drained my catch can and I got this out of it. I noticed that the seal on the bottom cap and drain was leaking a tad so probably lost a drop or two.
