A high school teacher, who I occasional help, does a great experiment for the students. He distilles crude oil to show the students where gasoline, etc comes from. His well has run dry and he needs another gallon of light crude. the tech service departments of companies are set up to send samples of this sort of thing. Can someone get me in touch with someone at an oil company that could supply a gallon of light crude?bjtindall@mindspring.com
