Does it need to be a very specialised oil? You used to be able to get 3-in-1 oil (if that is suitable) in small cans with a spout that would release one drop at a time if you were careful. I've used this on my model railway engines; I hope that this isn't doing them any harm!

Thank you for your advice Richard. I won't use my 3-in-1 again! I've only used it on a couple of old engines which I won't mind scrapping if necessary.
