I guess I'm at the other end of spectrum by simply following what the manufacturer proposes: I change my oil along with the filter every 18,000 miles, and so far, after 100,000 miles (and then some) have not had any issues. (My car is rather cheap, or in EV sense practically free, so I'm not all too concerned, either.)

The engine does not consume too much oil, either, so a single 4L bottle – about a gallon I think – is easily all that the oil I need between changes. With European prices, that is the equivalent of a single refill (even with my modest tank size), which makes you simply laugh and wonder at all the people that (always) bring up oil changes in the discussion of ICE vs EV. I can't but wonder how many of those actually own and maintain a not-imaginary vehicle.

What vehicle do you drive that you can get away with 18k mile oil changes? And are we discussing actual gas or that diesel crap?

thats a pretty standard recommendation from practically all german car manufacturers - to change oil roughly every 30-35k kilometers - which is about 18k miles.

I've never seen that anywhere in the United States. 10k miles is the highest I've seen for BMWs & if it isn't that, people say the typical advice is "once a season" depending on how you drive.

It's a VW Polo from the early noughties. Petrol, albeit a rather small engine to match the car :)

To clarify my earlier post, I meant of course that a single bottle of oil is enough for the refill (between 3 and 4 litres) and more than enough for any top-ups for the about 30000 km before the car starts to remind of the end of the “Long Life” maintenance cycle. Oil is certainly not up there when it comes to costs of owning a small car, ICE or not.

A cursory look at used oil: it's still rather like the stuff that goes in, albeit black, of course. Without specific tools, I think it's impossible to tell it apart from oil that's used for, say, 10000 km.
