Horrible Fuel Mileage!!!!?????
I have a 98 1/2 24v Cummins and for some reason i get HORRIBLE fuel mileage. 11 to 12 and i drive it so easy. I travel about 23 miles one way to work and i use an 1/8th of a tank. Something has to be wrong. I havent purchased any gauges for my truck yet but i will give you a little info to the best that i know. This is my first diesel and i feel i got a good deal on it considering fuel is 4.29 a gallon here in wv. It only has 158,948 miles on it and i payed 5500. I thought that it would get entirely better fuel economy that what it does but so far it drinks the fuel but the power is great. It is all stock except for a straight pipe exhaust. The straight pipe couldnt hurt fuel mileage could it? I have friends that get 18-21 mpg in their powerstrokes and duramax's. I drive it easier than ever, 50 to 55 on my way to work. Someone help me out

Fuel pressure could have something to do with it. If your really starving for fuel your going to have worse fuel mileage. My 98 was same way as your when I got it and the raptor I put on it actually helped fuel mileage surprisingly

Weak vp/bad injectors can be a contributing factor also
