Great question. Amsoil's gear lube study is outdated, so I am not sure if RP has improved their gear lube formulation. Amsoil's gear lube study embarrassed RP and I certainly wouldn't use it without seeing positive results.
Not many gear lubes can outperform Amsoil's Severe Gear 75w-90 and the price is great. BUT...Subaru syncros don't do well with Amsoil's gear lube. It is just too slick to downshift quickly (especially 2nd to 1st).
I haven't tried Subaru Extra S, but have heard good things. A product that has worked well for me is Redline Lightweight Shockproof.
Long story short, I would use Extra S in the gear box and Amsoil Severe Gear 75w-90 in the rear differential. Severe Gear (SVG) goes for $12.05/quart.
We come up to Omaha every month. Let me know if you need any product and we can always bring it next time.

Not sure if it was the RP but my trans/front diff took a poop on me.  Done dealing.  I'll find out soon enough.
FYI: I don't beat the **** out of my car.


The RP sucked in the cold. Only did it feel good when things were are warm.

i think its closer to the center.. 90/10 is not a subaru drive lol that would be horrible  ;D  iirc auto's are 60/40 or something like that.

I little research on the subject will reveal why they do it that way.  It makes sense as to why the do it as well.
