I've recently ordered some oil for my diff, but now I'm wondering if I ordered the correct stuff. I know wt and cst is competely different but when I saw 5000 mentioned assumed it meant cst.
When we say 5000wt, do we mean 5000cst or actual 5000wt (like 150,000cst according to a rough calculator I found)

Also does anyone know what oil is fitted from factory in a 210 RTR?
