I change every 24,000 km and I have never seen a filter like that either. I change oil when the service indicator says to (after I validated those intervals with 12,000/16,000/20,000 km changes on previous vehicles) and disagree with your assessment. I have no burnt oil. Or oil consumption. Or engine noise. I also use OE air filters so I don't have the additional dirt load that aftermarket filters can cause.

I don't call your maintenance practices stupid; it would be nice if you didn't call mine stupid or imply that I have been brainwashed by evil German engineers.
