There's an excellent post in there (twmattox) (with those foolish things I think called "facks") which reminds me of one of the critical deciding factors in gear oil: is there brass/bronze in there, or not? * Old transmissions (T-96...) with plain bearings and brass synchronizer gears CANNOT use "extreme pressure" additives, eg. anything with sulphur (sulphates, etc) as those EAT COPPER AND ZINC METAL (that's in brass/bronze). * That's a separate issue from the viscosity choice stuff that's partly subjective and use-based. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
