I'm wanting to learn how to make Biodiesel for my old mbz's. Is anyone in the LA area willing to give a few lessons?

Start here, and don't cut corners. Then if someone shows up you will at least have done your part to familiarise yourself to the process.

I make BD in the Los Angeles area. I would be glad to help. There are not too many of us in LA. Glad to have you on board!
