"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.
