Redline oil order grades

[180sxqc]

Hey guys,

I am doing a full fluid flush this spring and plan on ordering transmission, diff and engine oil. I am getting Redline oil.

1st question:

What quantity goes in the transmission?

3 quarts of Redline MT-90, I heard 2.8-3.0 liters is that right? Also read that mixing with HEAVY Shockproof should be considered.

2nd question:

What quantity for the diff, also what grade should I be using?

I read 2 liters of 75w90 GL-4 and it's a done deal

3rd question:

Engine oil, 4.4 liters of 10w40 (motor internals are stock) so 5 quarts, am I correct?

Just before you guys start bashing, I've been trying to find awnsers to my questions but figured out I would get more precise awnsers from the SR20 guru's in here

Thanks!!
