Just got back from a round trip from AR to VA and the Duramax 3.0 performed flawless and was super efficient. Going from AR to VA which was 700 miles we got 27.3mpg. Coming back we got 27.5. What was so impressive was my average MPH…73.4. I took a pic right before I reset after I just filled back up:

I almost have 3000 miles on the truck now. It has great power and is really quiet for a Diesel. I kinda miss the Diesel sound though.
Chevy updated the 3.0 for 2023 and bumped the HP to 305 and TQ to 495 and it did not effect the MPG it seems. If your on the fence for one then get off and go get one. I got 10k off sticker on a 2023 RST 4WD Z71 Crew Cab. The LTZ was 8500 off and if you like the High Country they were around 8000 off. The GMC versions were discounted a little less but i did see the GMC Elevation around 10k off. The 2024 models are starting to trickle in and not much has changed but they are discounted also but about 2000 less than the 23 models. You might have to travel like I did for a deal so be prepared. I did a 500 mile radius search and saw that St Louis MO area had great prices. Chevy still can’t beat Rams ride and interior though but I do like the large center display better due to its left to right layout. Go test drive one.
