How easy is it to convert my car to run on biodiesel or ethanol?
It’s not terribly easy to convert an existing car to run on biodiesel or ethanol, although in California, for example, about six percent of every gallon of gasoline has ethanol in it as blend. This percentage will probably be increasing over time to about ten percent. It does take a certain kind of carburation; the way you burn the ethanol and they way you combust the ethanol, and so it’s not terribly easy to convert. Old diesel cars can easily be converted with very minor modifications to run on vegetable oil (biodiesel) for a couple of hundred dollars. Of course diesel engines tend to last a long time so it’s well worth that small investment, especially when you consider that you can buy vegetable oil for as little as 99 cents a gallon.
