The supercharger uses ZC90 oil - from Fiat.
Or you can go to a car spares shop and get something like 75W 90, 80W-90 - 1 litre should do it.
Never run it low or without oil as the front bearings if damaged are £300.00 from Mr Croft and the gears you cant get!
Blower will be scrap.
You fill the blower by pouring it into the reservoir and allow it to to settle in its own time, you will have to fill and do this a number of times, oil level is correct when its in line with the seam on the reservoir.
If you are impatient like i am i would suck on the top breather pipe (i am disgusting like that) this draws down the oil quicker and cuts down the waiting time - do three loads and give it 15 minutes to see what happens, repeat until it full.
You wont get oil in your mouth by the way.
Check the level every 300 miles or you are at the mercy of old Crofty!!!!!!
