From that thread I surmised the below and use it when I'm deciding on oil
From protection stand point VW504.00/507.00 is most stringent approval in this C3 class and MB229.51/52 most stringent from deposit and NOACK stand point.
Find one that meets all 3 of the above should be a very good oil.
So I've been grabbing either of these 2 when it is time for a change.
Valvoline Synpower MST 5W-30
Pennzoil Platinum Euro L 5W-30
163k miles and no leaks or burn so far.
