The Quaiffe limited slip is a gear device. Very clever and very
complicated to describe. I would think that you could use the synthetic
gear lubes in such a diff. as long as there was sufficient EP additives.
Remember, you still have the ring and pinion to worry about. The lubes for
clutch-type limited slips have friction modifiers to allow the clutches to
grip. BTW, I think Positraction is a trademark of GM.
