The only Mobil 1 version that satisfies the VW 502 spec is the 0w40.

Amsoil European Car Formula 5W-40 Synthetic

Castrol Syntec 0W-30 (German Castrol). But more commonly Mobil 1 0W-40 (since it is more readily available at a better price).

Mann Filter

IMO German Castrol feels better than Mobil 1 0W-40.

I have been using motul xcess 8100 5w40 in my audis and my parents audis and love it. Engine is quieter which is impressive. I add motorkote every 3rd oil change. On the 2.7s i use the high capacity filters and on the 3.2 i change the filter half way through the interval.
