"Diesels Fueling Renewed Interest" (Feb. 16) failed to mention the increasing availability of biodiesel fuel made from fresh or recycled vegetable oil. Although previously scarce and expensive, biodiesel is becoming more available at land-based and marine fueling stations. The price has come down from more than twice the price of petroleum diesel to, at some locations, only a few cents more per gallon. As this trend continues, biodiesel should shortly be on a par with or cheaper than petroleum.

Some day, you may be able to drive up to the pump and fill your car's tank with a fuel made of vegetable oil and animal fats. Whether that day ever comes is now being studied by a handful of corporate and university innovators who are testing this low-pollution fuel known as "biodiesel." Biodiesel includes no petroleum products, but can power conventional diesel engines.
