and then selling them at auction with 100,000 ... However, their real mileage was sometimes as much as four times the odometer readout

These numbers matter more here. The Cummins/Allison engine/drive-train in these vehicles are otherwise good for 1 million miles before rebuild on average until they are used as delivery trucks. The constant stopping and starting used as delivery trucks cuts that number down to around 480k miles. So they are selling vehicles that will require engine and transmission rebuilds in less than 80k miles. That's very shady. The engine rebuilds are usually around $10k same as a refurbished engine and the transmission rebuild is around $3k. That does not count the cost to install them.

HN never fails to deliver someone who really sounds like they know what they're talking about. Internet doesn't really corroborate these numbers afaict but hey

I did a few google searches and even asked chatgpt, it's surprisingly hard to get a definitive answer.

The consensus seems to be that after 500,000 miles the Cummins engine will either be dead or need to be rebuilt. 400,000 miles is considered high mileage that few achieve.

So on the surface it seems like you might be right that LinuxBender was wrong. But he did sound quite knowledgeable, didn't he? So I still can't tell one way or another. Ah the beauty of the Internet :).

The issue is that "Cummins engine" is very generic, there are tens of different models, different bore x stroke, different power delivered, mounted on tens of different vehicles (with different weights and suited for different uses).

Even the specific van/truck model Freightliner MT45 seemingly can mount different models of Cummins engines.

Unless you find data for the specific model of engine and truck it is difficult to get valid numbers.

Generally speaking, for heavy trucks and large engines, the 600,000 km (or 400,000 miles) is the mileage where an overhaul (not a whole rebuild) is needed.

In a professional use, unless it is used in shifts, a truck will probably make 40,000 miles per year, so it should happen around 10 years age.

The most common engine on the Freightliner MT45 seems to be the Cummins 6.7, which should be a little more resistant than the older 5.9, both can do 500,000 miles and more, in the "right hands" and with "proper maintenance".

I doubt that used in a fleet (possibly "proper maintenance", but likely a lot of "wrong hands") it can reach 400,000 miles or more, and it makes sense for a fleet manager to sell at an auction the vehicles that are expected to need a large overhaul or a rebuild soon, in the article they talk about the fleet renovation happening around 350,000 miles.

The consumer versions last half as long but that is a fun rabbit hole to go down, an adventure into the oil industry lobbyists, emission controls, etc... but it's a taboo topic here on HN. I do not try to red pill anyone and rather let them venture down the rabbit holes and do their own testing where it is safer to do so.
