Differential Fluids - For those who used non OEM fluid
I'm only interested on people who used aftermarket fluids such as Motul, Royal Purple, Red Line, etc... which one did you go with and did you run into any problems. I'm leaning towards Red Line 75w-90, Royal Purple 75w-90, Motul 75w-90 or Motul 80w-90. There are also people who used 75w-140. Please advise

Whatever we're tuning!
Motul Gear 300 75w/90 is what we currently use and you will not aerate/foam the Motul. You could also use Motul Gear FF Competition 75w/140 which we also use. Either one and you are good to go!
Problem fixed.
