The difference is that when it happens to a Porsche, the repair options are extremely expensive compared to other marques and hence we freak out about it. If there were $15K repair options out there (like in the UK) instead of $35-40K like here in the US, it would not be such a big deal. Also, I have read about others with this problem in other makes of cars that just keep on driving them and adding oil when needed and the cars end up lasting way over 100K miles so they’re not as concerned about a few vertical scuff lines in the cylinder liners as we all seem to be. LOL.

Oh, and I have an Audi A4 daily driver that burns a qt of oil every thousand miles since new and has soot filled tailpipes. Never scoped the engine but wouldn’t be surprised if it did have scoring. Now at 78K miles and don’t care even if it did to be honest as it still drives fine.
