What they said, + new air filter, keep yer tires aired up, and dont believe the console MPG readout, its lying to you, so drive her till the light comes on, put some gas in,write down how many gallons + odometer reading, run down to fuel light on again, and do the math.
I have the 5.9 with permanent awd 128,000 miles and average around 13 or so mpg, but she still needs a little more TLC yet so it may improve, I gotta fix the big stuff first !.
I dont know what vehicle you had before this, but if you are used to "Lesser Trucks", then I imagine the D may have come as a bit of a shock to you. Myself I ran an old Ram 250 longbed truck into the ground for years so I knew what to expect. My wife however found it a little shocking.
IMO though, best vehicle on the road, and though she pulls at the purse strings a little and hurts me sometimes, worth every penny. Not many cars are built like a tank, show a clean pair of heels to the kid at the lights in his export, and can do it whilst pulling a house behind it or moving half your mates furniture, in comfort, and looks good doing it !
Keep her a while and then think about going back to anything else, I know I will hang on to mine till gas is $10 a gallon or the wheels fall off.
