2024 Chevy Silverado 2024 3.0 Duramax Fuel. The duramax diesel engine not only offers the highest torque available in chevy’s silverado lineup but also the best fuel economy. The 2024 chevy silverado zr2’s duramax diesel engine has proven efficient, but we weren’t ready for its astonishing best tank of 34 mpg with 826 miles of range!

Looking at a new 2024 at4 and just curious if the 10 speed transmission helps with mpg. My previous 3.5 f 150 had a 36 gallon.
