Id bet the redline 75w-140 will have less FM than OE.

I just changed my rear diff fluid to Redline 75w140 (with no added FM) and it seems alright. Definitely locks up (eventually) and doesn't chatter at all. Now this thread has me worried about accelerated clutch wear  |
Redline 75w-90/140 has FM in it.
Redline 75w-90NS/140NS has no FM in it. NS is short for no slip.
If it doesn't have NS after the viscosity...you're good to go.
