i have a 2006 dodge 3500 single wheel with auto tranny truck only has 48k on it and intown i get very bad mileage i only got 60 miles on a 1/4 tank truck runs good i just had the cummins dealer do a oil change and change the air filter didn't help my 1999 dodge 3500 duelly cummins with lots of power upgrades beats my 2006 in fuel mileage any day so what could be wrong with my 2006 it's a lot of money to fill up

 

First get a smarty or a tuner you preferr Stock these trucks suck but with a few mods 20 are possible! In town willa lways be bad due to getting three tons to move from stop to stop is hard on fuel! If your going to run errands in town use the little car! truck is for work but if it's all you got then a tuner will get you 15mpg in town with a light foot!
