75/110 or 75/140 is best to use in our diff.

i used 75/90 in my diff and it started making noises. Used Motul 90PA after and haven't had any problems since.

Ive always used mobil 1 75w90 and have never had any problems. Diff is dead silent and drains clean and clear each time with minimal paste on the diff plug.

^ +1. I use Motul 75w-140. FYI not all 75w-140s are the same and u should pick one as close to oem specs or maybe just slightly thicker for proper differential operation.

1. Even for a car driven in the cold Indy winters? Or, should I stick with the 75/90 (using Amsoil)?
