Advantages & Disadvantages of Biodiesel Compared to Petroleum Diesel
  • Made from non-petroleum, renewable resources that can be produced domestically
  • Can be used in most diesel engines, especially newer ones
  • Less carbon monoxide, particulates, and sulfur dioxide emissions
  • 78% less carbon dioxide (CO2) production
  • Biodegradable
  • Non-toxic
  • Safer to handle
  • Slightly lower fuel economy and power (10% lower for B100, 2% for B20)
  • Currently more expensive
  • More nitrogen oxide emissions
  • Transportation & storage of B100 require special management
  • B100 generally not suitable for use in low temperatures
    B100 thickens at temperatures under 40 degrees F.  Additives and blends can be used to reduce these problems.
  • Concerns about B100's impact on engine durability


B100 is 100% biodiesel, B20 is a 20% blend of biodiesel with petroleum diesel.

Biodiesel fuel is safer than petroleum diesel as it produces less greenhouse gas emissions, and less air pollutants. Also, as seen in the chart above, it is non-toxic and biodegradable, and overall just safer to handle then normal petroleum diesel. Of course, there are disadvantages too as seen above as well, but the fact is it's possible the advantages outweigh the negatives overall.
