Biodiesel is a form of diesel fuel manufactured from vegetable oils, animal fats or recycled restaurant oils.


Features of biodiesel:


  • It is safe and biodegradable, and produces fewer air pollutants than petroleum-based diesel. It can be used in its pure form (B100) or blended with petroleum diesel.
  • Common blends include B2 (2% biodiesel), B5 and B20. B2 and B5 can be used safely in most diesel engines.
  • However, most vehicle manufacturers do not recommend using blends greater than B5, and engine damage caused by higher blends is not covered by some manufacturer warranties.



● can be used in most diesel engines, especially newer ones

● produces fewer air pollutants (other than NO x ) and greenhouse gases

● biodegradable

● non-toxic

● safer to handle.




● use of blends above B5 may not yet be approved by manufacturers

● lower fuel economy and power (10% lower for B100, 2% for B20)

● more NO x emissions

● B100 generally not suitable for use in low temperatures

● concerns about B100’s impact on engine durability.
