2024 Chevy Silverado 2024 3.0 Duramax Mpg. Fuel economy of the 2024 chevrolet silverado. Speaking of speed, the revised duramax makes for a noticeably quicker silverado.
Looking at a new 2024 at4 and just curious if the 10 speed transmission helps. A quick reset of one of the two trip computers and the next 162 miles registered at 22.2 mpg at an average speed of 72.7 mph, pretty much matching the 22 mpg the epa says the truck should achieve.
