What’s too high mileage for buying used diesel truck?

Truck prices are outrageous. My f150 is on its last leg and looking at used diesel trucks. I’ve never bought a diesel. What mileage or age would you try to stay under buying? I won’t put too many miles on it and won’t be towing anything major except maybe a camper to and from the hunting camp. Thanks in advance.

At one time high mileage for diesels was 300,000+ but they would go 450,000 to 500,000+. Nowadays not so much. For "newer" diesels with more current emissions (EGRs, DEF, etc).. if you can delete then 225K to 250K is good to go for another 100K to 150K+ miles with minimal maintenance and repairs. Drivetrains are generally solid even with high mileage.

If you can't delete then be wary of a high mileage diesel. Just too many problems with the emissions stuff. Of course if you know your way around diesels that is a bit different. I work on mine and the emissions issues are a pain in the arse. I'm at 264,000 on my F250.

Just my opinion.

I've always heard that diesels are just getting broken in at 100,000 but curious what the more experienced guys say as well. What is the life expectancy of a diesel or when do they start having problems? My uncle drives semis (different I realize) and he owns a couple of rigs that have huge mileage on them. One in the 800,000 mile range and one over a million.

I'm looking for a 3/4 ton diesel as my next vehicle. But like you said, the truck that I really want is way up there in price and I'm having a bit of a difficult time justifying paying that much for a used vehicle.

I got no idea about a diesel but a gotta gasser that is about to push over 450k. Same motor but I did have to have the transgender mission rebuilt about 9 months ago.

Vortec for the damn win....now the sumbitch will probably blow up on the way home from work.

I know a few baws with the duramax that have over 500k without touching the engine or trans. These are work trucks that tow heavy all the time.

The answer ranges anywhere from 20k miles to 500k miles depending on countless factors.

I wouldn’t touch a newer diesel that’s outside a good warranty.

It depends on the maintenance on the diesel
Just dropped 5k on a 141k mile 99 f250 diesels can get expensive quick.

Get a newer 3/4 ton gas. I have a powerstroke that's been good but fuel is high.

In my opinion, If you aren't exceeding the load capacity of a half ton truck there's no reason to purchase a diesel. Fuel will cost you an additional +3K each year + service and maintenance. DEF fluid sucks as well.

If you want the extra tow capacity beyond a half ton, but not diesel, you might want to consider the 7.3L V8. There's a few decent deals on used 2021 gas F250's for around $60K.

Stay away from diesel unless you need one. The EPA killed recreational diesel in the US.

You don’t need a diesel. You want a diesel.

Stick with a gas burner. If you want a 3/4 ton get a gas burner. I have 2500 Silverado gas burner and it pulls anything I need it too without the excess maintenance.

Have you looked at how much diesel cost vs regular gas?

Deleted farm truck F250 with 200k, changed a few sensors and the primary water pump.
I fully expect it to last 400-500k

For comparison…..

200,000 mostly highway miles is about 5000 engine hours.

Equipment is designed to go 10,000 hours before major failure- B10 life, meaning 90% of the components will make it to 10,000 hours.

The 6.7 Cummins in the Ram is the same engine (labled as FPT in that application) in Case IH small Magnum tractors, New Holland T7 tractors, and many pieces of Tigercat forestry equipment.

If I was in the market for a used diesel truck, I know what brand I would look at.

I’ve had 5 f250s with diesels. I drove all of them till 300k. No major issues. My first one with a power stroke made to 800k on the farm before I parked it!
