i use fuchs titan/silkolene pro s fully synthetic 5w40 in my 2002 bug but it is like the most expensive oil there is pretty much.... you dont have to use this exact oil but i wouldn't go buying cheap stuff as these engine's need oil pressure as for which to go for a 5w40 0r 10w40 is best and always get fully/ester synthetic rather than semi lots of good oils to choose from here http://www.opieoils.co.uk/c-952-fully-synthetic.aspx plus you get membership discount there hope this helps
