Step 3: Getting bio-deisel

Picture of Getting bio-deisel
So all you really need for bio-fuel is filtered deep-fryer grease, If you live in a moderately sized city this can be obtained easily. I live in a little place called Boise Idaho and there are people offering free grease on craigslist weekly, and you can even hit up local fast-food vendors. They usually have a big stinky tank of it out back and usually have no objection getting rid of, you'll just need to get some big barrels or drums to put it in.
