Interesting that this topic should come up. I had a guest speaker from the Hoquiam biodiesel facility come in to do a presentation for my kids today. She said there are numerous "do-it-yourself" operations throughout the country.....all legal and safe if done correctly.

I don't own a diesel but if I did, with prices the way they are, I'd probably look into it too.

It's an amazing fuel when compared to the like of petrol diesel.
