I recently purchased a differential with a kaaz lsd on it. What are some gear oil options besides kaaz oil and about how long is the longevity of the lsd. I drve the car 2-3 days out of the week and nothing too crazy.

 

I use 75w90 in my kaaz and it works well for street or track use. there should be a lot of brands that sell it - mobil 1, redline, lubro moly, etc

the diff will last for a long time. have fun with it

 

I run Motul 90PA on my KAAZ unit
