hi guys

I want to know which fluid are you using in your rear clutch-type differential... What brand do you use and what viscosity is the best for this LSD???

thanks

Am I better to use Motul 90 PA diff oil (mineral oil) or Motul competition gear 75w140 ( 100% synthetic) or any other suggestions....

i use 90PA becuz its cheap.. its mineral and probably wont withstand high speed (more heat) compared to full synthetic ones but i'd rather do it 2x or 3x than running expensive oil

and i believe 90PA got some friction modifier like stuff in it for clutch type LSD's
