Putting biodiesel in your car is easy, but finding biodiesel isn't. Biodiesel stations have normal-style fuel pumps, so you just need to stick the nozzle into your car's tank and turn it on. It pumps just like petroleum diesel, but it smells better.
Unfortunately, biodiesel pumps aren't as common as gas stations. If you don't live near a biodiesel station, you may have to get it shipped to your house. The National Biodiesel Board maintains a map of retail biodiesel distributors
at its Web site, Biodiesel.org
. Some of the retailers are fixed locations, while others will deliver biodiesel to your home.
Although biodiesel is sold by the gallon, the price differs greatly from seller to seller, as there is no standardized biodiesel manufacturing industry. Biodiesel distributors might make their own from used vegetable oil or resell biodiesel from a refiner. The source of the vegetable oil used in biodiesel is usually industrial food manufacturing facilities, such as potato chip factories.
