Hello My name is Joshua Kilen and I am from the US.
I am wondering what is the best type of compressed air lubricator? A fog/mist type or a Oil drop type? The steam engines I am will be running are in this Video: https://www.youtube.com/watch?v=Gn3NYN0dA6E
This is My channel and I do have other steam engine videos on my channel, here is the playlist of my steam engines: https://www.youtube.com/playlist?list=PL2xuU9q-UnTN9WUIdilVOpTlmv740ggL6
a nice thick machine oil or gear oil. Something with no sulphur or detergents.
others may know more.
