Agreed. Click the "Garage" link at the top of the page, then under "Your Garage" is a "add new vehicle" link.

A fuel log is also a definite must--whether or not you choose to use the Ecomodder one. Almost no one I've ever seen makes significant progress in improving their mileage without keeping careful recrds--they're essential to knowing what mods (vehicle & driving) work and which ones don't.

I think you are out of luck. There's not much you can do to get decent mileage out of those big, diesel trucks:

First, what sort of driving are you doing? Are you driving a lot of highway miles to get to job sites (in which case aero mods should help), or are you burning most fuel at low speeds out in fields?

my driving is mixed literally this next time i fill is really going to be bad i had to load and deliver locally 3 machines i serviced one at a time and yes i charge for the fuel but any savings i can pass off to my clients means happier clients and more return clients. i made the garage im going to track my fuel usage through here and update every one as well whether its highway or city driving at the time

i forgot to mention my girlfriend me a scan gauge not sure which one though but at least ill be able to have a number in face helping me drive more efficient

[Gealii]

the cool thing about fuel logs is you can put in the details whether it was mostly city or mostly highway so you can always compare future tanks with the past to see if you had any gains

I'm a huge believer in re-time FE feedback, however, I haven't had any luck with accurate ODB-based instrumentation on my truck. Mine doesn't directly broadcast fuel flow and air flow based methods are useless on a diesel.

I assume you '99 still has mechanical fuel injection, so I doubt it has fuel flow available over OBD, but I wish you luck.

[monster76]

My 99 has H.E.U.I injection and the throttle is drive by wire. Hopefully it does have fuel flow availible it would be nice to have real time economy

600 miles per week wow! I dont even want to think how much in fuel you have to spend each month. I hope you can write it off.

My dads '02 F250 7.3 automatic, 2wd gets high teens on average. He just came from an 800 mile road trip-mostly interstate, and said he got 23 mpg on the way up. Hes got a hard tonneau cover and I forget rear gear ratio but I think its 3.73. He tows a bass boat and enclosed motorcycle trailer regularly and he said on the interstate he gets about 14-15 pulling them on average. He has aftermarket exhaust and a chip that gave him an extra 50-60 lb/ft tq over stock.

On the flip side, my brother has two 7.3s in his landscape truck fleet and he is always complaining what fuel hogs they are. But they are driven mostly in town, lots of stop and go, pulling trailers and hauling heavy stuff. He's gotten as low as 6-7 mpg he figures at the worst.

I installed the scan gauge and so far driving like i normally do, it has been showing 13.2 mpg but that was strictly city driving it go will go up when i hit the highway. And yes fuel is a big expense i can spend any where from 700-1000 a month but it is part of the work
