Self-Maintenance Fluids - Would someone verify these?
My car is: 2005 Z51 C6 MN6 in the Dallas, TX area (**** is my current choice im leaning towards)
6 qts of Oil 5W30. Royal Purple, AmsOil, Redline ****, or Mobil 1
4 qts of ATF Tranny Fluid Redline Synth D4 ATF****, AmsOil Synth Universal ATF
3 qts of Gear Oil 75w90 Redline Syth Gear Oil (this appears to require the redline Friction Modifier), Ams Severe Gear Oil (does this need any additive???)
Coolant I read the capacity is 12.3qts. Since it doesn't get that cold down here i was going to maybe 70% distilled water (roughly 2 gal) and a watter additive (Royal Purple Ice, WaterWetter) and the rest coolant sticking with DexCool. Will any Dexcool work?
Clutch FluidI read any DOT4 Brake fluid will work here, probably don't need the Motul RBF600 for my clutch but ill go shopping here. I checked this is quite dirty so this will be changed soon!
Power Steering FluidRoyal Purple EZ fluid or another synthetic fluid as well.
Please let me know your comments.

I used Mobil 1 tranny fluid in my C5Z for 6 years with now problems.
I used Redline rear gear lube in my 97 and never had an issue with it. I had a bottle of GM's friction modifier to add to it in case I had a problem with the diff clutches but never used it.
Just make sure you use enough Dex (or equivalent) to protect against corrosion inside the engine. That amount should also provide enough water pump lubricant although you can always add a coolant additive (not water wetter) to get the protection without using antifreeze. I am not sure what the additive is called anymore but it was popular at one time because people would use it to refresh the green antifreeze so they didn't have to change it every two years.

Though the AMSOIL Severe Gear does have friction modifier in it, for your C6, I would recommend a few ounces of friction modifier to prevent diff chatter.
And, pulled this off this link from AMSOIL which you might find handy (for your 05 C6):
AMSOIL Online Product Application Guide

[1] After refill check oil level.
Note though it says over 4 quarts for tranny, I've not heard of one that acutally took that much and the same tranny in both my 02 Z06 and my (recently sold) 06 CTS-V both took about 3.5-3.7 quarts or so.
