MOTUL Gear 300 Question

trohde78 · 03-04-2015, 09:34 AM

I was looking at changing my rear diff fluid with Gear 300, but I read somewhere that it has friction modifier additive for LSD's. Is this still OK to use in my open diff? Am I better off just sticking with the normal Castrol oil for a DD?

mmm motul.

They have two differential fluids, one for non lsds and other you guessed it.

You can use the LSD fluid in a non LSD diff but not the other way around. The friction modifiers for the LSD do nothing (good or bad) to an open diff.

That makes sense! Thanks for the input.
