Flathead Fan Oil

I took apart the fan assembly that I plan to install on my 8BA flathead in order to clean and paint and was surprised to find that the hub was filled with oil and some water. What is the purpose of this oil besides lubrication? How much and what weight of oil should I put back in when I get it back together? The fan comes from what I think is a 1948 M2.

I use 30W in my fan on my '48 F-1. Check it every time I change oil.

Ya most it's mentioned is your year service lube and maybe oil. Is to put some oil (engine oil) in the cup really. 30w then
