For that big and heavy of a truck, 18.1 mpg isn’t bad at all. I have a 2022 LT Duramax and I’m at 16.9 at 10,600 miles and that includes towing. I’m usually 18-18.5 not towing. My display is pretty spot on with the pump. I really can’t complain about that. My 04’ Expedition used to get 12, so it’s still a big improvement. The 35 gallon tank seems to be a really good size and offers a lot of range. Sometimes I only fill up once a month.

I have 6.6 duramax history In the past . I had a 2013 Chev duramax diesel. Beautiful. It drove perfect and with grace and power. I’m in the market again for a 2024 Chev 2500 diesel duramax 6.6 L !
-
I get a pretty decent mpg towing for work almost daily with my 2023 Silverado HD. Helps that it's a diesel ofc. I like the looks of the 2024.
-
Gale Banks has a great video showing the updates to the engine. One of the biggest changes is stronger valve springs for more engine braking.
-
GM has always been known for the best ride in the HD market. Independent front suspension is a big part of that!
-
Great video! And I have a suggestion. It would be nice to see a comparison chart at the end of the video of previous generation trucks. Ford and Ram as well. This could be with all your videos, including the Ike Gauntlet and anything else. Thanks!
-
Great data point. I think a longer run that includes a regeneration would be more indicative of real world expectations. My guess is (like Ford) it will stretch it out on the highway and suffer when in stop and go and hills. Regenerations will definitely have an impact, but curious about how much of an impact. My 2022 Ford F350 CCLB with 6.7 has impressed me over the last 3400 miles (since new).
-
Seems pretty solid to me. Likely better than my '15 Sierra 1500 6.2 with level and KO2s.I'm happy when I get 18mpg on an all highway trip.
-
Thanks TFL for making all these videos!
-
I love your YouTube channel I drive a 2021, 6.6 Duramax. My fuel mileage got better after 25k miles. I think that’s pretty good fuel mileage I think they get better after they get ran in
-
For a engine that most likely isn’t broken in not bad mileage. I see the MPG just getting better as the engine is broken in.
-
Got me all excited thinking it was the 6.6 gas with new 10speed. Hopefully you get that video up. Thanks.

I’d like to see TFL undertake a long/term 3-5 year longevity test that focuses on HD Diesel reliability between the big three brands using real world use over an extended period. The KPI’s to include reliability, regular maintenance cost, tracked warranty issues, one-off maintenance cost, truck performance, and trouble free motoring. For $80 to $100K purchase price of todays vehicles, we consumers expect greater reliability included in these vehicles. No more junk GM, Ford and Dodge.

My 2020 regular cab 4.3L 4X4 1500 would have pulled the same number. This is very impressive, adding 4 additional gears really helps.
-
2022 Ram 2500 with the 68RFE has 100 miles on it did a 150 mile run similar road conditions the truck had 20.5. calculated mileage was 19.8mpg. not bad for new and the 6 speed tranny. I just went from a 2017 Duramax with the 6 speed alison which was very similar mpg. Like both trucks..
-
My 2011 1/2 ton Sierra with small lift kit, 34 inch tires at 65 MPH on level surface can barely manage 18-20mpg. For this truck to get 18mpg is impressive.
-
I have a 22 with about 30k on it. A couple weeks ago, we drove from NC to AL, about 340 miles, and I made myself stay near the speed limit for a change. I averaged 22.6 mpg on that trip! The truck is unforgiving when I get on it though, it typically does 18.5-19-ish with city driving or steep hills. Gets 10-12 towing 15k#.
-
I drove my family members 2019 duramax empty no wind 120 miles which mostly highway and I got 24 MPG. I towed 13k 5th wheel on my return trip and got 12.5
-
As time goes bye it only gets better, that’s my experience with my truck.
-
Would like to see how this mileage compares to that of the 6.6L gas with the 10 speed tranny.
