Chevron W680 as cylinder oil?

Re: PDF Book on Triple and Quadruple Expansion engines

Thanks for this excellent publication! Long nights of study here for me. I also have the original Scientific American article about the "ARROW", a yacht that put Turbinia to shame in the late 1890s.

Hello from Oklahoma!

Long time lurker, but I finally had to register. I'm currently a boatless college student, but I hope to get into the hobby in the future. In the meantime, I'm designing an engine to go in the boat.
