Does the maintenance manual for this particular drive even recommend lubrication of the carriage rails? I can envision that a drive kept in hostile (i.e. corrosive or very dirty) conditions might have some damage to the rails or slides that might be temporarily helped by a lubricant. It would seem that the long-term fix is to get things squeaky clean and smooth.
The maintenance manual doesn't tell anything else than "replace [spesific item]". Too bad they stopped making them in 1987...
The rails are of metal, shiny and smooth (steel I think). I can't see anything wrong with them.
