No, NS stands for "no slipperiness additives"

The regular oil is the NS oil PLUS the slipperiness additives (moly dithiocarbamate, etc), which do not let clutch type LSDs work properly, because the clutch plates will not lockup.

Since we have a regular diff, we want MORE slipperiness, not less, so NS is definately not the way to go.

More slipperiness = lower temps and less wear in a standard diff
