Thanks in advance Ernest Bourgeois
Gear Oil - It takes 3 quarts
The limited slip differential design has been extensively tested with high quality NON-Synthetic 80W90 hypoid oils ( regular mineral based oil ) treated with GM or Ford friction additives ( 3 oz. of additive will treat 1 quart of oil ). To avoid differential clutch chatter ( noise ) and for optimum performance, use the oil and additive described above. Use of other additive and oil types may cause differential clutch chatter.

I have a question that I have not been able to get a clear answer on,
maybe you guys can help. Does Torsen AND Auburn require a source of
friction modifier??? If not, which one does and which one doesn't and
why? Thanks in advance. Sorry to ask within this post.

Friction modifier is for helping the friction components (clutches or cones) used in positraction style differentials to repeatedly grab/slip without shuddering.
Torsen has no clutch/cone friction components, and so does not require friction modifier.
