Can you help me understand what is Differencial with Limited Slip (4×4) and just Differentials 4x4

Is this LS is a choice in the lubricant or this is the technical specifications of the Differentials assembly?

Small difference. But its ok to use 80w90 GL5 oil in ur vehicle. Em sure prev. owner would have been using 85w140, so now 80w90 would be just fine.
