Hey all! New guy here that is thinkin about buyin a Duramax truck! Ive got a few questions that I need honest real world answers to before I make any firm decisions... The question at hand is what kind of mileage do yall gett out of your trucks? I know there are several different engine platforms but I dont know if that has much bearing on mileage. I am "most" interested in what kind of mileage is capable in a bone stock truck. If I get one Ill add the basics like exhaust, intake, tuner.... Ill spend most driving on country roads followed by highway drivin then a little bit of city driving but not nearly as much as the other two. So lets hear it! What are ya gettin out of your trucks!
