Hey, quick question: When punching in g002000 into a local parts database, four candidates come up: Castrol, Lucas, Febi/Bilstein and good old Pentosin 7.1. I know on the UrS6 you have to use Pentosin 11s. Is it permissible to use any of the other non-pentosin ones? They're quite a bit cheaper. Thanks, Rokas 95.5 S6
