2025 Chevy Duramax Mpg Range. The 2025 silverado duramax acted as a tow rig for us this week, and actually ended up being quite enjoyable to rack up some miles on. Pickup trucks have a wide spectrum of interior configurations and available.

Chevrolet has made big improvements to the 2025 silverado hd 6.6 duramax turbo. Looking at a new 2025 at4 and just curious if the 10 speed transmission helps with mpg.
