Biodiesel Facts

  • Biodiesel is a clean-burning, biodegradable, alternative fuel produced from vegetable oils or animal fats. To be called biodiesel, it must meet American Society for Testing & Materials (ASTM D-6751) quality specifications.
  • Blends of biodiesel can range from one percent to 99 percent. Common blends used in Iowa are B2, B5, B10 and B20. Many farmers use even higher blend levels in their equipment.
  • Biodiesel provides engine lubricity which helps extend engine life and reduce maintenance costs. Even biodiesel levels as low as one percent can provide up to a 65 percent increase in lubricity.
  • B100 reduces ozone (smog) formation by 50 percent.
  • Biodiesel is a biodegradable, renewable fuel with positive performance benefits. Increased cetane, high fuel lubricity and increased oxygen content make it a preferred blending agent for ultra-clean diesel.
  • As a domestically-produced fuel, biodiesel can reduce the need for fossil fuel and improve the nation’s energy security.
  • Biodiesel is registered as a fuel and fuel additive with the EPA and meets clean diesel standards established by the California Air Resources Board (CARB). B100 (100 percent biodiesel) has been designated as an alternative fuel by the U.S. Department of Energy and the U.S. Department of Transportation.
  • Using biodiesel in diesel engines does not void parts and materials workmanship warranties of any major U.S. engine manufacturer. For a list of engine manufacturers and their biodiesel warranty statements, go to: www.biodiesel.org/resources/fuelfactsheets.
  • Biodiesel blended up to 20 percent exhibits cold flow properties similar to #2 diesel and can be used year-round.
  • Biodiesel has the highest BTU content of any alternative fuel (ranging between #1 and #2 diesel fuel).
  • B100 reduces exhaust emissions of carbon monoxide by 48 percent and hydrocarbons by 67 percent. Sulfur emissions are essentially eliminated with B100.
  • Biodiesel is cost-competitive with conventional diesel. The long-term savings in reduced wear, repairs, maintenance and lost down time make biodiesel the best choice for America’s trucking industry.
