You don't want it full -- I'm not sure of the capacity, but the easiest way to fill it is to get an irrigation syringe from your dentist or pharmacist. This is a 10 mL syringe with a curved tube on the end rather than a Luer needle seat. The tube is fairly small and will fit at least part way into the pin hole.

Remove the bimetallic spring and carefully pull the pin out. Pour the oil into the syringe with the plunger pulled all the way out, then insert the plunger and use the tip to guide the oil into the pin hole. Will probably take a while, the oil is pretty vicsous.

If all the oil won't fit into the syringe at once, repeat.

I would put in 1 and a half bottles of oil, no more. If you want, you can try just one and see if the fan works -- spins up on startup then slows down immediately, and pulls when hot. If not, go ahead and put half of a second bottle in, too.

DON'T fill it all the way up -- fan will pull ALL the time, not just when hot!
