Biodiesel

Arkansas-specific information will be coming soon. In the meantime, read more at the Department of Energy's webpage on biodiesel.

Basic information

When biodiesel is blended with petroleum diesel, it produces a fuel that is compatible with diesel engines, displaces imported petroleum, and reduces harmful emissions. Blends like B2 (2% biodiesel and 98% diesel) and B5 (5% biodiesel and 95% diesel) are becoming increasingly common as drivers become more aware of the many benefits. Biodiesel blends of 20% biodiesel or more are also widely available and may qualify for credits under the Energy Policy Act of 1992 (EPAct).

Biodiesel is manufactured by chemically reacting vegetable oils, recycled cooking grease, or animal fats with alcohol. Today's biodiesel is primarily made from domestically produced soybean oil, which has extremely low sulfur content. As long as the biodiesel used for blending meets ASTM D6751 standards, low level biodiesel blends such as B2 and B5 can be used safely in any compression-ignition engine that is designed to be operated on diesel fuel. This may include diesel-powered cars, trucks, tractors, boats, and electrical generators. More information on biodiesel compatible vehicles is located here.
