Have always used the Bosch Supers (copper). Tried the regular Bosch Platimums once and didn't seem to run as well. Judgement based on feel of course. I was under the impression that torque spec's were for clean and oiled threads. Dry would seem unpredictable (how dry is dry?). However, oil turns to carbon if heated high and long enough. Anti-sieze is aluminium or copper base. Once heard it affected heat transfer.
