Seriously.. some trucks just seem to get better mileage than others. Is it the engine? Drivetrain inefficiencies? The position of the moon when the truck was made? All I know is I lucked out in my '05. It's not the best mileage I've heard about but it's as good as my '99 was, so that's all I can ask.

I'm getting steady 12 to 13 pulling up to 30,000 gross, some tanks at 13.7 or so, but then mine does not really count or compare, too much done to it. It does show the capability though.

why is there such a difference between truck. 8 mpg is a gasser type fuel mileage and that sucks. what can i do to improve it? bomb the truck? drive it off a bridge and quickly jump out beforehand so i can collect insurance and buy a new one that hopefully is better?

first off, the engine will get better when it breaks in. They take about 50k or more to break in. I would think that the 315 tires would hurt the mileage towing also.

geez i didnt know it was that long for them to break in. i figured the tires might be a small problem but i didnt think theyt would hurt that bad. i would think that the bigger tires would allow faster srudsing speeds at a lower rpm and not much torque being robbed. perhaps i am wrong. i vcould use a bit more umph at take off and to keep it from downshifting on hills. i know the tires keep it from staying in the sweet spot on grades.

I think a lot has to do with your driving habits. When I drive, I dont mash/step down hard on the throttle to get going or while cruising. I use light throttle and let the animal do its thing. I set the cruise control on flat land, and take it off when pulling hills. My fuel mileage changed drasticly when I added my fuel box. I went from 10 up to 15 miles per gallon instantly.

It seems that on some other threads that cleaning the sensors may be a cause for bad fuel economy. You may try checking some of the links on that, or possibly take it to a Cummins dealer to check out. I am not sure if additives like Power Service help(they claim they do), but if they keep the sensors clean, pumps lubed(they seem to fail too often), and injectors clean, it is proably worth the money, especially with diesel fixin to go strato in prices.
Other things, new Air filter setup or replace filter. May check the timing & valves also(Dealer?).
Driving habbits & air profile matter also. I get 12 or so at 60 mph with a high profile 5er, 12', 13k weight. 17 solo, all with 4.11 gears. My worst day was maybe 10 +. Have 17k miles on the truck. Most members here can't stand to drive that slow. Perhaps as fuel goes up, they might. Drove 540 miles this weekend on I10, and passed only 2 other vehicles at 60mph in that distance. It is nice to put on the cruise & let it go.
You have a problem and with diesel being so expensive & going up again, I would get it resolved.

well based on what everyone is saying, 15-15.5 isnt too bad for a 600 4X4 with 315's. but when towing it sucks. i guess ill try some different things when towing like not tryin to speed race from s stop light or allowing the truck to downshift alot on grades. we shall see how future trips go. i doubt there is anyhting wrong with the motor.
