The site owner at Renntech, Loren, maintains a very accurate list for Contributing Members. We are not allowed to post it on other sites. The list is several pages long (12?) and contains hundreds of approved oils br brand and country locations.

The only Porsche approved oil viscosities, for modern day Porsches (for example 996/986 and newer) are 0W40, 5W40, and 5W50.
