Engine hrs vs miles
I’m new here. Recently picked up a 2018 F250 xlt and I’m still sorting things out and learning. Truck is relatively high miles, but seems to be in good condition and well maintained. It has lived its life in NM (Farmington area) and was a ‘corporate/fleet’ vehicle. Any thoughts on the engine hours & idle hours vs miles? I did some web searches and there is some info out there, no firm consensus and I was quickly overwhelmed.
Cheers,

Here is from my last truck.
My 2021 at last oil change with 124,050 miles on the odometer
engine hours 3,159
idle hours 993
I idle a fair amount.
If the truck is in good shape and sound good, doesn't drink oil all might be well. What engine?
Only average 33.5 MPH, and idle for over 60% of its life, YIKES!!!

Is it gas or diesel?
If diesel, I would dump it fast, going top need a DPF replacement soon I would bet.
If gas, might be looking for a new cat pipe soon, but they are lots less expensive than a DPF.

You are right of course, it's a lot of engine hours, effectively a 290k mile truck on the motor and associated parts.
Despite people freaking out it’s nothing to worry about. My last 6.2 had over 20k hours with 13-14k of them being idle hours. Sold it with the original cat(and original everything else except spark plus, wires and belts) and the guy that bought it from me has been driving it daily for 3 years without engine problems.
The last company I worked for ran a whole fleet of 1 ton trucks that idled like this. Most of the gas and a few diesels(deleted). The GM 6.0L and the Ford 6.2L didn’t have issues. The only time we had issues is with one guy that just couldn’t be bothered to get his oil changed. (Btw a GM 6.0 will go 5k hours on the factory fill, they are amazing motors).
The dodges we had a lot of issues with the gas motors, so much so that we weren’t aloud to order them and only a few trickled in every now and then.
Edit to add: the main thing with idle hours is to change the oil by the hours not milage. I do mine at 200hrs on gas motors. 300hrs on diesels. I’m sure you could go longer but it makes me feel good about it(OLM is usually around 40-50%)
Thanks for the info. Yeah, it’s a 6.2L gas engine. Does not appear to burn oil and the Carfax report shows regular maintenance/oil changes at dealer. Dealer replaced all 4 shocks, battery and fuel pump prior to me purchasing it. Only issue I noted was a slight tick at idle (IMRC?), no loss of power, backfire or anything like that. I’m getting 13.5+ mpg according to the computer. It’s not going to be a daily driver, probably 5-7k miles/yr. Light towing (3000# camper), so I’m hoping it will last me a while. Fingers crossed!
As long as the oil was changed alot then should be ok, but it is a high mileage motor. More than the ODO indicated.

For some reason, that truck ran while sitting still a LOT. It's fives year old and it sat still while running for 260 days. And if you figure 8 hour work day with 5 day work week it makes me wonder what if any work did the truck do.
That's what some people do...even on perfect weather days...sit in their car with windows up and engine running.

The biggest issue was deep cleaning the interior a couple times and flushing out the ac box. Literally had to cut a hole in it and use a hose. It was a 2013.
1- In a lot of industry a work day might be 12hrs, plus some time to cross shift so 13hrs is normal PLUS then you have to drive to base which might be and is typically another 1-2hrs each way, yes long days. So when working in cold climates(-30 to -40) the truck isn't getting shut off as it gets cold to fast so you can put 16hrs a day on the truck. Say you work 24 days a month thats almost 400hrs just in one month with 312 of the, idle time.
2- The "work" the truck does is provide a office for a supervisor. This work most likely will require electronics so having the engine running to power them is what happens. Yes sometimes a generator would be a better option but as someone that has been in industry for 20 years it doesn't make as much sense in practice as it seems it might.

If you see regular maint. on it, I would not sweat it much, I would say on the majority for most of us, if that is "MY" work truck, I treat it as mine and take care of it accordingly, the one thing that doesn't always withstand the idle hours though is the seat cushion...
esp. my RAM... it was crap after the first year.
