It's me again. I just purchashed a Clausing 5914, that hasn't been used in a while. I'm thinking about changing, or just adding oil to the headstock and apron, but having some trouble finding the recommended Shell Tonna 27 for the headstock and Shell Tonna 33 for the apron. I have Mobil Vactra #2, has anyone used that? Will it work in both locations? Thanks in advance, Jim.
