It's designed for synchromesh trannies.
:edit:
NM... I see MTG is the spec viscosity & also designed for synchro trannies.

The dealership is "confused." Service manual specifies any API GL-5 75w90 or 80w90 gear oil. Go with Amsoil SVG 75w90

I remember reading somewhere Infiniti puts friction modifier in the differential fluid when brand new to assist break-in. Thereafter it is not required. Just make sure you have the correct APL rating. This goes for all Nissans.
i put a differential fluid additive which i think was AMSOIL into my LSD on my 89 supra and it helped with chatter, i don't know if its good to put it in my VLSD on my sedan since it dosen't have clutches but some silicone mechanism instead, my diff isn't chattering but i'd like to keep it running better
