Yep, great for precision oiling, but they really upset military police when you take your tool box into a secure area and you have 3 or 4 diffrent loaded syringes in there :-0 Great way to carry a small qty of oil, light oil and grease (use to have both moly grease and silicone in the tool box that way) With reguard to the syringes, get the ones with the o ring like plunger, not the ones with the big rubber bung! I use to find the plastic needles to create a lot less agro taking stuff on sight than the blunt dispensing style needles. Get the right size and there tapered internaly, you can then cut them back and wedge a WD straw in there for really awkward to get spots.
That said for cutting oil i still like a small brush for tapping, more to brush the chips off than paint the oil on! The secret i find is to have just a dribble of oil in the tub. Any more and it gets messy!
