How can I convert my car to be fueled by cooking grease instead of gasoline?

mom101 asked: I saw a segment on TV, where a man converted his car to use cooking grease that he obtained from a local fast food joint, instead of gasoline. He said anyone can do it. How can I? Can it be done to a mini-van? What better way to solve the overpriced gas issue?

What are the long term effects of using plain filtered used cooking oil in a diesel engine?

Bigfatbino asked: I saw this on Mythbusters. They filtered some used cooking oil, put it in a diesel engine, and got 30 mpg from the car. Sure, they proved it would “work”, but could you keep the car functioning by simply using filtered used cooking oil as a fuel?
