Default Diff Oil Weights and their effect on 4x4

I have an OFNA Hyper 10SC that I purchased used. As with any used RC I have torn it down and am rebuilding from ground up. I will be using this for indoor carpet offroad on a VERY tight track, so the race is made in the corners.

So I am not asking for someone to tell me the perfect setup, but explain the effects of different weight oils in the diffs...

So how do different weight oils effect the center diff?

Also with a high traction surface and very tight corners, a few 90s and 180s, do I want loose diffs or very tight. In the 2 wheel drive world, a tight diff would cause a push through the corner, right? So does the same apply front and rear on a 4x4? Do you generally want more or less diff in the front on high traction surfaces?

Any help is greatly appreciated! Thanx in advance!
