My point was that this is not any sort of widespread normalized behavior in the US in the past few decades. I was responding to a comment preaching as if this was routine behavior, and that people not doing it are simply being "inattentive".

I do get that it used to be a thing in the past. But that was also when oil was rated for 3k miles (I think? maybe it was even lower) and engines would routinely burn oil (ie consume it without leaving a drip spot on the ground). Whereas in the modern day, 15k synthetic exists.

FWIW, I probably do more of my own maintenance than the median HNer. I'll admit I can let intervals slip more than I'd like and I'm working on that, but this idea that everyone is checking fluid levels all the time just seems wildly off base.
