This really isn't news.... And, it's really not a big deal to process. Diesel engines will run veggie oil with no problems (or modifications) at all. The only issues are that A) Waste veggie oil is dirty and B) veggie oil is pretty thick. All you really have to do is install some sort of filtration system to take the 'dirt' out, and a heater to thin it out before it hits the engine. A lot of times you don't even need a special fuel pump. My sister ( http://www.tonyakay.com/ ) has been running her Jetta on waste veggie oil (completely free of charge from local supermarkets who have to PAY to dispose of the oil if she doesn't take it from them) for about a year now. Long trips and everything, and she still gets her 40 mpg that a Diesel Jetta already would. -A
