Refilling the oil in a hydraulic door closer?

The screw marked "BC" on my hydraulic door closer shot out while I was opening the door, and a bunch of oil poured out of the hole before I was able to put the screw back in. Now the mechanism seems to gurgle. How would I go about replenishing the oil in order to fix the gurgling? The whole thing still seems to work, so is it also fine to leave it as-is?
