.... and restaurants will pay you to haul their used cooking oil away.
old news, commercial biofuel producers and co-ops are rapidly sucking up used veg oil so major restaurants are getting paid for waste oil now, and to run a modern diesel you need to make very clean fuel, not simple or cheap .... OTOH if you have some mom&pop fried food place handy you might make a deal with them and run the straight stuff in an old Detroit, as environmentally un-friendly as they are
