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

Hi Dave Greetings & warm welcome to the forum. Re: how much oil to use in a D14 ?, there is an oil cup on top of the steam chest, unscrew the cap & top it off, make sure to put cap back on as this is a steam escape route if cap not screwed back on. fit. a drop of oil on all moving joints is sufficient. no oil is to ever be put inside the boiler.
