      MPG at 600 miles

      100% agree, there are a lot of variables. I definitely do not drive I’ve like a grandpa but also don’t drive like I stole it. Truck is currently in the shop so I’ll have to get weight later. The price for driving it doesn’t bother me. My precious was a 6.2l so the cost between the two is a wash.

      summer road trips in the 2026 2500HD

      By c4racer2 · Posted

      that is pretty awesome MPG there!  I think so far one observation is these trucks do way better on MPG under 65mph vs 70+ and they really suffer at 75+   I noticed on the stretches into NE on 76 and 80 which is posted 75MPH and I was doing 82 I was getting more like 13.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      No ETA is available for that engine at the moment in the GM system.   I would start at the dealer.  Try and talk to the parts manager or service manager and see if they can start a CX Connect case and get an ETA from GM on when engines may be available.  If they just check Parts Workbench and say "no eta", they aren't trying hard enough.  They need to do a CX Connect and chat with DPAC to find the ETA.

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.
