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

I like to stick with the commercial steam oils. To me the finest is Green Velvet. I have bought it by the 5-gallon pail for my 7.5" gauge steam locomotives. Green Velvet was developed by the Skinner  Engine Company for their steam engines. It is not a viscous oil and is light green in color. It is perfect for model engines.
