Style chooser

hi

i been using motul 90 pa for my gearbox with 1.5 way lsd. when taking slow corners the chattering sound it not obvious.
recently i upgraded to motul gear competition, and straight out of the workshop the my lsd is chattering quite loud whenever i take slow corners. (the shifting is much smoother though)

it is any problem like the mech put in too little oil or something like that? or is gear competition creates more friction for the lsd.

thanks
