In simple terms...
in front, the heavier the diff oil, the more traction you will have, but it takes away steering.
In the rear, the heavier the diff oil, the more traction you will have, but at the expense of steering, "rotation" in a turn, and stability over bumps and ruts.
In the center, the heavier the diff oil, the more aggressive the car will feel.
