I know this thread is a bit old, but I referenced it before I bought my rig. I bought a 2019DT , 87k ( so you can see why I was interested in engine hours ) It did help me make my decision. Mine has 87k miles. 2200 engine hours 90 idle hours. Yes somewhere just below 5%. Yep, I said she was a keeper when I saw that. The other rig, i was looking at, had only 41k miles. But it had 550 idle hours and 1000 engine hours or something. I was about to pull the trigger on the 41k rig.. but this flipped me 100% It tells you much more than just miles. So when I saw that on the lower mileage rig, I immediately asked the the salesman for the carfax.. and when he walked up with he said it was fleet lease. So, not that is not a good idea to check carfax , as it can tell you a lot. But it tells you how important and useful this engine hour stuff is. So , I ask you now , you are looking at two trucks , one with 41k and the other 87k. Which do you buy? but the 41k has 550 idle hours and is fleet. the other is 87k 90 idle hours, one owner. local owner. If I could tell you how many vehicles I saw imported from all over the country , obviously auction rigs. I even was looking at one, when my wife noted a ghosting of a sticker from auto dealer in Canada. I dont need a cold weather car, when I live in the south. 25 below starts are extra wear on the engine.
So , my point is we have to think about use of vehicle when buying used not just mileage.. I hope someone can benefit from my buying experience. I am hoping I have good 3-4 year old rig that was gently used for a very consistent 2200 miles each month that seems to involve not a whole lot of stop and go. Truck should be good for another 100k easily.
ALso, it seems very apparent that, some of the EVIC ( I think base ones ) seem to reset at 1000. From what I am seeing in the threads, and the trucks I shopped, the numbers make sense if they are off by 1000. Some may be off by 2000. It still seems you can deduce useful meaningful information from these.
