Not sure what you mean by steam oil, In mine when I finished running for the day I put a couple of drops manual transmission oil into the cylinders etc to stop corrosion and pistons sticking. Water gets everywhere as the steam condenses. But sounds and smells like a real steam engine when running. Just make sure you are using distilled water. If you need parts I bought a new steel gas tank and other bits and pieces from a supplier in Great Britain. "Forest Classics" /media/tinymce_upload/ba64ce563ad27f34c03635710f975f77.jpg
