I don't think so. Light oil will spin the inner rear wheel, while you want more of a locked diff with both wheels spinning.
Light oil in center will spin and balloon the front wheels under acceleration, heavier oil will distribute the power more equal between front and rear. Sure it will drift, but not rwd only drift.
Heavy oil in the center diff to distribute power to front and rear equally. Heavy oil in the front to help lock it up and and transfer power to the rear. Heavy fluid in the rear but not as much as the front so it will kick the rear end out giving you the slide effect.
