This is a re-post from a different thread I'm copying here in case it helps anyone else with this issue who finds this thread instead of the other one.
**********************************************************************************************************
Well well well. Ever since I started investigating my engine idle and drive hours relationships (see posts 11 & 20), I've been logging those hours every two to four weeks. Since I realized my drive hours had almost certainly reset at some point in the truck's past, and thus were probably MUCH higher than they registered on the display, I wasn't worried about regularly logging them as much as when I first made post 11.
Well yesterday I happened to scroll down to the idle/drive hours page on my truck's display and GUESS WHAT I SAW???
Caught red handed!
For the data-driven people, here is how my idle and drive hours had been progressing up to this day:
So, rest assured, the drive hours most certainly DO reset, for what reason I don't know. But if you're concerned, just log them once every two weeks or so for about 10 data points, graph their slopes like I did, and project those slopes from 0 to estimate what your true drive hours likely are, instead of the knee-capped value registered on the truck's display.
I hope this helps put some of your concerns to rest. Good luck driving!
