So 75w140 wouldn't be too thick for our diffs? I've used LE607 and LE1605 through most of my S2000 ownership. When my 06 was new, LE actually quieted down the diff quite a bit. I'm curious about this Amsoil severe gear stuff. Any huge differences between their 75w110 and 75w140?
I used to mix Mobil Delvac 75/90 and 80/140 in a 50/50 mix in my over the road truck and when I retired I had about 1 1/2 gal left so I use it in my S and any other vehicle(my bike to) that takes a GL5 lube. Some very good lube.

There are two channels in the diff housing's casting.
One below the pinion shaft and one above.
They both connect the area between the 2 pinion bearings with the area where the Torsen (and most of the oil) is.
As far as I understand oil is thrown from the top of the ring into that top channel and returns via the lower one, IOW there is some oil flow.
Driving forwards....
Also, IIRC, the oil reaches the middle of the pinion, when stationairy.
That level will drop a bit when you drive as oil will stick to the ring and stay in the Torsen unit.
Still, I think the contact patch is at least partly submerged in oil, even when you're driving.
The pinion head itself will pick up oil too as the lowest part of it is always submerged.
