2024 Silverado 2024 Duramax Fuel Mpg. I understand this is a long way from your 2024 question but this is my experience. 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!

We cringe at the thought of what effect a heavier load would have on the truck’s. The diesel greatly improves on those.
