For getting oil into joints, I was thinking about getting some mineral oil (getting away from the weapons grade stuff I used to use), and using a syrringe to get it into the joints. I am not thinking of some sort syrringe used by medical practitioners, but rather something like what Zebco reel oil comes in. I recall seeing them online once, but can't think of exactly what they were listed as, and can't recall where I saw them. What is the correct name for this item? Is this something that most (decent) hardware stores might stock? How tricky is filling them?
