Engine hrs vs miles

Hi,

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,

John

That truck idled ALOT.

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?

Man! That truck would scare me!!!
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.

it's a gas looking at the 6k redline on the tach.

You are right of course, it's a lot of engine hours, effectively a 290k mile truck on the motor and associated parts.

Looks like a 6.2L

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%)

All;

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!

yeah alot of idle time in the ac or with the heat on.

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 what it's worth, here's a little perspective on idle hours. My crown vic with 140,000 miles has only 315 idle hours. However, a lot of police and taxi crown vics get well into the 4 digits for idle hours.

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.

I had an auction 6.2 like that, very similar. Was our backup truck.

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.

How did we ever buy a vehicle without the hours and idle hours I'm surprised we survived

A couple of things here:

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.

I don;t think anyone is freaking out, but the fact remains it is a truck with close to 300k miles worth of wear on the motor, climate control system, catalytic converter(possible more wear since idled a lot), electrical system, etc on top of 140k worth of driving wear on the driveline. No one knows how it was maintained. It could run for another 200k or something can come up, OP just needs to understand that and plan accordingly. The 6.2 is a great motor but the mileage+idle hours is high no matter how you slice it.

^^ X2 on this, my work truck is my "office, lunchroom/breakroom, charging station and napping quarters on long days/nights" when it's hot, yes it idles a lot, as it is a cooling station when the laptop and myself need charged and I don't need to be plugged into equipment (or I have the long cable that will reach if I send it out the window) when it's cold, same thing. I don't recall the idle hours on my last work truck but I do know it was higher than a normal DD or commuter truck, I do ensure it is serviced regularly, as it needs to get me to the site and back home daily.

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.
