Transfer Case Fluid: Diaqueen vs. Amsoil Severe Gear 75W-90?
I guess OE is Diaqueen
vs.
Amsoil Severe Gear 75W-90
http://www.amsoil.com/catalog.aspx?code=SVGQT-EA
For my 05 GSR.
I know many people are very firm to say ONLY Diaqueen in the t-case, but I don't really know why the Severe Gear wouldn't work.
HELP!

I just had my T-case rebuilt by Shepherd and Trevor told me NOT to use amsoil (which I have already purchased). Now I am pretty worried, do I really need Diaqueen or is he misinformed?

Trevor is amongst the least misinformed when it comes to Evo TC's and Transmissions. Trevor, Jon Shephard, Jon @ TRE and Jack @ Jacktransmisisons have all recommended me OE Diaqueen for my TC, so I see no reason to use anything else.

I'm using Redline heavy weight shockproof @ SAE 75W250 for 3 years with no issues. It’s a tad thicker then Amsoil Severe Gear 75W-90
By all means, I'm no expert in analyze fluids. I personal like the thicker fluids because it has to protects better at higher temperatures keeping the fluid stable. With that said, you can't go wrong with Diaqueen.

I'm not saying, but I'm just saying I ran Redline 75w90 back in 2003-2004 and destroyed two transfer cases just driving to Portland and back. Now there could have been many other factors involved (not full enough, etc etc) but on the 3rd transfer case I ran straight 90 weight (which is what it calls for) and never had another issue. On my 06 Evo I've been running 90w and its been fine since. If I change from 90w I'll run something like the 75W250.

The only other recommended aftermarket gear fluid to use in t-case and rear diff is Motul 90PA. I have it in my EVO X without any issue and the car seems to be smoother.

I use amsoil fluid for oil and in my tranny/rear diff. Up until now, no one told me this was an issue so I am a bit uneasy at the moment. At the end of the day, I do not want to take a risk, so I will put in whatever is required.
