Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

In the states you can get these oilers on Amazon for ~$10.  I've had one for years.

In the reviews many people complain about them leaking.  I haven't had that problem with mine, but the oil I use is my standard "oiling" oil: hydraulic fluid.  This might be a thicker oil than some people are trying to use.

This oiler and a plastic needle tipped oiler with steam oil are my goto's for my steam engines.
