what kind of grease do I use for my SOTA Sapphire bearing?

SOTA the company is just a phone call away, in CA.

I guess that they moved to Wisconsin from Illinois recently .  

Thanks for correcting me. Years ago, I think they were in CA. In any case, they are very good people who would guide the OP in the right direction.

It is a very heavy, tacky oil they are using. Sota will be happy to sell you a small plastic dropper bottle which will last you 4 lifetimes. Go to their website and get the phone number. If a woman answers with a husky voice that’s Donna.
