Just wanted to share a nice trick I've started using. For more precise amounts and placements of your grease or oil try filling a syringe with it. You can use one with the threaded needle fitting to allow the use of different sized needles to either access small areas or control the rate of flow so that it works grease with anything from a thick grease to a thin oil. Right now I've used it well with an 18ga hypodermic and Triflow Synthetic Grease (which is pretty thick and tacky) to a 24ga with M1 20W50- though that doesn't flow very well, definitely for precision oiling only. The only concern I have is hydrocarbon break down of the plunge seal as I have not been able to find any that specify what material is used there.
