SC fluid
Ford part number E9SZ-19577-A, synthetic Supercharger Fluid, comes in a 4 oz bottle, i paid about $15.00 . I've seen posts that you can use the GM stuff which makes sense since they also use an eaton blower, and i think it's cheaper. I've just used the Ford stuff because it doesn't take that much fluid so the cost difference is not really a bit deal to me.....
