High Mileage Trucks: PSD and Cummins and Duramax

Have not watched yet but 275k IMHO is NOT "high mileage" for a diesel.

275k for ANY engine may or may not be high mileage. If one figures life expectancy to be 250k in a light duty pickup use, the 275 becomes high mileage. No e of the pickup .motors will generally speaking get a million miles line the 6 cyl motors in class 8 rigs. My IDI 7.3 was known as a 100k mile throw away motor back in the day. The I6 motors were expecting 400-600k miles depending upon usage.
Psd7.3 and B5.9 got iirc around 450k before needing rebuilds back then in MDT use.
I haven't paid much attention the last decade or so on engine life, but the blocks seem to last, it's the add ons like fuel system, computers etc that seems to fail, hence getting rigs put in recycle/junk yards.

Most trucks go to the junk yard with perfectly servicable engine cores.

The body, suspension and interior wear out before the engine does.

Curent 2008 V10 has just shy of 250k miles on it heading home from Alaska/Yukon trip right now.

Might still be too early to tell and I don't live in the rust belt, but it appears the aluminum body panels are holding up well to the road salt, but not sure about the frame and suspension components

Aluminum body panels solve one issue but interiors and suspension parts still wear out.

It's economics, if you throw enough money at it, you can keep any vehicle going. But when the truck is only worth $3k in good condition, it doesn't make a lot of sense to dump thousands into thousands into it to keep it in good condition.

My 99 Tahoe had over 250k and ran great when traded. But that is no surprise running AMZ/OIL 15-40 Diesel and Marine oil. :B

Here's some more high mileage trucks for sale: Of course for your viewing entertainment. These are two clean trucks for their mileage.

Here's another interesting high mileage setup

My 2004.5 duramax which I passed to my son has turned 260K miles. He (and I) don't figure that's high mileage, but getting up there. BTW my 95 S-10 with the gas V-6 hit over 250K and no real maintenence issues.

500K, how many get there? Probably not many, but I suspect the reason is split between engine/transmission issues and just to many years and other stuff wearing out and "old age" setting in.

I doubt my old 2004.5 will hit 500K. even with the miles our son puts on it, 20-25K/year that's another 10+ years. By then the truck will be 30 years old.

And my 2015.5 only has 70K so it likely won't hit even 250K with me or son as owner.
