The viscosity of the oil limits the independence of each side of the diff.
If you run a heavy oil, the diff will act more and more like a solid axle.
If you run light oil, more of the drive will be sent to the wheel with least traction/loading.
So its a balancing act really. You need to weigh up how much grip is available, and consider how tight the track is and set the oils to maximise forward drive without giving too little steering for the track conditions.
