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

Think I'll try and source some Castor oil, perhaps a small bottle at the drugstore, and give it a try if a hit n miss ever shows up at my door. Heck, I still have some old model airplane engines lost in storage that I may try and drag out and give a spin one of these days, just for memories sake.

Benol is still available and smells the same! And claims to have reduced "gunking" on the bottle now.
