I know this has been covered but i couldent find what i was looking for regarding torsen diffs in particular

i have been doing a lot of research on oils for differentials. it seems most people opt for the redline 75w90. i have also read that torsen differentials are particular in the oils used. i run a 4.88 torsen, is redline 75w90 or valvoline 75w90 a good choice for this diff?

thanks
