SoCal Veggie oil-driven cars on the rise

"But diesel mechanics here, in Los Angeles County and elsewhere are busy converting cars and trucks to run on vegetable oil, which only works with diesel engines. And they say the popularity of these conversions is increasing."

"...while veggie cars do cut down on fine particle pollution and greenhouse gases, they could increase emissions of nitrogen oxides, which help form smog."

"Another caution: while Internal Revenue Service officials say they have no requirements for consumers who use vegetable oil for fuel, state Board of Equalization rules say they should be paying a state excise tax of 18 cents a gallon. Failing to pay it could result in an audit and even a penalty."
