All, I tried the "Index Quattro" command and it told me I'm not a member of the list 'quattro' What can I do. ---OR--- I just purchased a '90 200t that is using synthetic motor oil. I missed the earlier debates on it, and am wondering which brand is best for use in this wonderful automoblie. Information regarding either would be greatly appreciated. TIA.
