just some 0w-3O weight oil which Castrol produces in germany and imports over here. Very similar packaging but the back of the label says made in Germany. Many have hypothesized that its the European Castrol SLX oil, it definitely looks and smells different that the N. American version. Initial testing by some of us has shown some very good performing oil but the jury is still out until we get more results. Not sure how it compares to the N. American version either.
