Maybe. From the back label on Amsoil's "Synthetic Gear Lube SAE 80W-90":

Compatible with synthetic and petroleum gear oils and most limited slip differentials. If limited slip chatter occurs, add AMSOIL Slip-Lock friction modifier additive.

Boss, friction modifier is available at dealers, most auto parts stores, 4x4 acc stores, and speed shops. On line too, of course, but shipping on a couple oz would be ridiculous.
