Greg,

Can't answer any of your questions yet, but soon, maybe. The Biodiesel I was given was not a commercial product but was made locally from waste oil for personal use by a small fleet operator. I don't know what it was that I ran, quality or otherwise so when I came across the specs on how to make the stuff, I thought I'd give it a try. Just for fun, you know?

Sunny and calm today. Decisions, decisions.

Go flying or run engines?
