That said you should use an oil that meets ACEA A3 and generally one that is either 0W40 or 5W40 unless you have a specific application that indicates otherwise ( racing, arctic).
M1 0w40, M1 5w40 european car formula (different from truck version, though that's probably OK), Shell rotella T6, Castrol Edge 5W40 European Car, or their similar 0W40 - many of these available in wall mart.
That said there is a list of oils that have passed Porsche's A40 tests and are approved. Being on this list is good. Being off it may mean they didn't spend the EUR 122,700 for testing.
So bottom line, yes. And anything is better than being low.
