You'd be surprised. The person who sold me this one did. When I think back on how the whole buying process went, it was not like anything I'd quite experienced before, and I think she was actually more interested in screening out someone who wouldn't look after it, than simply selling it.

The price on it was already so good I didn't try and haggle it (and there was a vibe there that made me think it would not only not achieve anything, but would very likely kill the sale on the spot). She wound up coming down in price on her own, anyway, in a cost split arrangement to share it 50-50 on whatever needed work the inspection turned up). Later, after the sale was inked, I learned it had a very strong sentimental value to her, and other remarks made me think too it was not the typical sale.

She definitely cared about it even after it was sold. It was very atypical, nothing like any other used car buying experience, and probably pretty rare in today's society where things are so disposable. She was pretty well off too, and didn't need to hang onto a car 10 years before selling it.

I could probably go table limits on whatever I commute in, since the twenty five miles each way gets everything warmed up and dried out, and the proportion of time spent in open loop is tiny.
I do change the oil every 5-6K generally, and the longest I have ever gone in any car in similar service is 7K.
The owner needs to be honest about their use of the car.
If the engine is not routinely run long enough to reach operating temperature in daily use, a shorter OCI is indicated.
Too bad only GM has a really sophisticated system to determine oil life in actual use.
A really good system would take all of the worry and speculation out of the oil service life equation.
It may also be that experience has indicated to other manufacturers that a mileage recommendation is more than adequate to deliver long engine life, so there is little advantage in going to the expense of including a really sophisticated OLM system.
