I wanted to jump over here to the Commercial Truck Forum to ask a pretty elementary question from you experienced guys. I continue to do research in identifying the best 'hotshot' or 'flatbed LTL' rig to build for this type of work. I keep going back and forth between the idea of running a smaller truck like a Dodge 4500 with the Cummins engine, pulling a 40' gooseneck or fifth wheel flatbed tagged at 36k versus stepping up to a Class 7 or 8 single axle tractor pulling a longer stepdeck that might be tagged for up to 54k. Of primary importance in the comparison is operating costs, especially fuel economy. So today I'm trying to learn that as I look at used tractors, do the computers provide history on actual fuel economy that can be downloaded?
Is past fuel mileage available from a truck's computer

Yes. The dealer will connect a laptop to the ECM outlet, and pull up all the history on the trucks data. It usually cost around a $100 for a dealer to do it
Nottoway Thanks this. -
Yes, most contemporary electronic engines in class 8 vehicles have a computer with that capability. If you take it to pretty much any shop with the ability to work on such truck, they can "dump" the ECM history for the life of the truck, and that data will include the historic MPG as well as other parameters.
As for a medium duty vehicle, I would assume the same thing, but have never had the occasion to actually find out.
Good luck.Nottoway Thanks this. -
And don't assume that the mpg reading from the ECM is dead on. It will be close, but I have found over the years that many mpg readings out of the ECM tend to be on the high side.

Really stored fuel milage is calculated fuel milage. May differe from real about 5-10%
Nottoway Thanks this.
