2024 Duramax Fuel Mileage Per Mile

2024 Duramax Fuel Mileage Per Mile. I was at my dealer for service to my 2022 zr2 this morning and they had a white 2024 2500 hd zr2 on the floor optioned out on the sticker at $87,905. Your gmc sierra 2500 service interval occurs every 7,500 miles.

Still, an average of 13 to 15 mpg is pretty respectable and is on par with gm’s, chevy’s, and gmc’s rivals from ford or cummins. Record how much gas it took to refill.
