ive seen a bit of research on this matter in our cars, and in short, penzoil platinum euro (from natural gas) is best followed by mobil 1 euro. Castrol is actually towards the bottom in overall ranking. I run mobil 1 0-40I run non-euro oil in my car. Have been for years and it has not blown up. If you feel better about it then when it's time to change it again put VW spec oil in it.
the whole VW rating ties back to turbo heat issues (oil gumming up etc). so yeah, run whatever oil you want, but if you want to run it hard, i would put trust in what the nerds at VW figured out. its cheap insurance
