"Why would anybody ever bother with Romanian" The Thomas Crown Affair

I made biodiesel 14 years ago. I have been running Straight Veg Oil since. I use to use a paint stirring attachment on the end of an electric drill. In an 8ish gallon metal bucket. If you are really trying to make biodiesel cheaply just to see if you can do it. You probably have the drill and paint stick around the house. Turns out making good biodiesel is expensive. And time consuming. Just my .02 cents.
