Hey Nick 986, welcome to the Forum.
Don't worry, there are NO bad or wrong questions here! Just bad/wrong answers (and I have hundreds of them!
).
I agree with Paul.
Another great Porsche approved oil is 5W50 Mobil 1. If you can find that oil in your part of the World, I would use it. We don't have this viscosity in the USA. Our friends in Canada do.
