LSD Oil Change....what weight??

[Gavster]

Hey guys...Ive been searching about this but I cant seem to find what I need;

I have a Nismo 1.5Way LSD, and I need to change the oil. I currently have the 80w90 Nismo LSD oil in, and Ill probably put Royal Purple in since I have easy access to it and its a decent oil that has LSD additives...anywho, I need to know which weight to select. I figure their 75w90 is a good choice similiar what ive got...but maybe the 75w140 or 85w140 would be better? What would be the contrast id notice? Would the 85w140 be ok? Thanks for your help!

85-140 would work in HOT climates. the lighter is fine for all climates except arctic. the thicker will lower milage slightly. Royal purple, Motul, Redline, and Mobil one (with addative) would all work. Mobil one will NOT work in transmission though

wow 85-140's a bit thick. I'd suggest 75-90.
