210 Gear diff - viscosity question

[DangerCow]

I am building a gear diff for my DEX210 and am about to fill it with fluid. The question I have is, I have some "10,000 cst" fluid, and was aiming to fill with a light 1000wt fluid I saw in an online build guide:

as well as mentioned in some set-up sheets. Is my 10,000 cst in that ballpark? It is the lightest I have in my collection. I will be running an indoor-carpet winter-series.

Thanks for the help!
