old 944: to mineral oil or not to?

[thom]

When an engine gets old, it seems to be advisable to switch from synthetic oil to mineral oil. Is this true in the case of the 944?
I'm quite confused with this because the owner's manual says ALWAYS to use synthetic oil whereas some friend of mine already use mineral oil in his turbo...

Cheers guys

Greg, my car has been running on 0W40 for her first 60,000 miles (read since new) and was not showing any leaks when I switched to 5W50 (couldn't find 0W40 anymore).
Given that the engine is getting quite old, am I about to be the witness of leaks? 60,000 miles doesn't sound old for an engine, especially a Porsche one.
By the way when can one say that an engine is old?

Domster,
Do I have to understand that if now I use 5W50 I shouldn't come back to 0W40?

Don't worry for my friend's turbo; I may have misunderstood him when he told me about the oil he uses
