I own a truck but my MPG is bad.
I have a 06 Pete 387 with an Cummins ISX475ST - 475 HP - and a Eaton Manual 10 Spd transmission. I pull flatbed loads averaging 40000lbs.
I'm currently doing like 4mpg. I don't know much mechanically speaking.
When I take the truck to the shop what can I tell them to change, replace, tune up that will improve my MPG. I think I'm doing horrible.
Please help!!!

Stop doing 80mph. That will give you a huge improvement.

Run the overhead, check CAC for leaks, check air filters,give it a good dose of injector cleaner. If you don,t have a MPG display get a scan gaguge, always check you mileage the old fashion, not just with the computer.
281ric and blairandgretchen Thank this. -
Both the previous posters offered good advice .
How much UNNEEDED stuff do you carry in the truck , knew 1 guy complaining about poor fuel mileage and he had 500 LBS of weights he carried but never used for exercising while on the roadgpsman, blairandgretchen and comoes3 Thank this. -
I probably carry 500+ pounds of tools I HOPE to never use...but I know if I DON'T have 'em, I'm guaranteed to need them.
tommymonza and gpsman Thank this. -
Slight difference between TOOLS you may need and a 500 LB portable GYMN you never use
281ric Thanks this. -
We need to know what speeds you run, what gears, what tires, where you run and what type loads to be able to help you more. I would think to be getting 4 mpg you either have to be really mashing on it , have a mechanical issue or truck is just set up completely wrong for your operation.
RERM Thanks this. -
When you say truck is set up wrong for my operation what can I do to fix that. I really need help as you can see. -
Running the overhead is basically getting the valves adjusted and the CAC is the charge air cooler. It needs to be checked for leaks. -
