The Porsche TSB has 0w-40, 5W-40, and I think one (Mobil 1 Peak Life) 5W-50 from various companies. Temp use ranges are listed, as are countries/areas of the world.

I use un-approved Motul 300V in 5W-40.

Some of the approved oils are barely adequate, and some I would not use if they were free. There is a world of advice available.

Use an ACEA A3/B3 or API SL or better. No SM or CJ oils.

Call or e-mail Charles Navarro at LN Engineerin for help/advice.
