Well, like it says in the title: What brand of fluid (that works the best) should I put in my differential, and what is the weight? While I am on this topic, what is the best fluid for the tranny? Thanks.

I use Redline 90w Gear Oil in my diff and Redline 90w MTF in my tranny. I have been using both for years with very good results.

Does it make a difference that I do not have a LSD diff.? Cause I am pretty sure that I dont. Would the 90W gear oil still work? If it makes a difference, I have an 87, not sure what model, but it came stock with 4 piston calipers in front, tupperware spoiler and tupperware ground effects, and turbo seats.
