Have you looked into WVO? I just bought an old diesel VW Pickup. Diesels will run on almost any type of oil (peanut, soy, kerosene, waste vegetable oil, etc.). Stop by your local Chinese food restaurant and fill up for free. Some filtering required to get the fortune cookie crumbs out first, of course.
No, but I read about it. Being retired, I drive so little that it is not a personal issue, just one I have been interested in for a long time. Have you heard about the turkey oil coming from processing plant in MO ? That's a good one. If the EPA stays out of it, Yankee ingenuity will triumph.
