Biodiesel Fuel

Biodiesel is produced from virgin vegetable oils (typically soy in the U.S.) or used oil or rendered products. It is typically blended with conventional diesel and the most common blend is B20 (20% bio and 80% petro-diesel). B20 may be safely used in any diesel engine. Winter cold flow issues are successfully managed with use of additives.

• The cost of B20 is typically roughly the same more or up to 10 cents more per gallon than petroleum diesel (other blend levels are relative to this cost comparison).
  
• Biodiesel produces significantly fewer emissions (unburned hydrocarbons, toxics, CO2, CO, particulates, and others), except for a slight increase in nitrogen oxides.
  
• Biodiesel has greater lubricity, enhances cleansing properties and a higher cetane rating compared with conventional diesel.
  
• It has slightly lower energy content. However, practical experience has shown that use of blends of B20 and possibly lower increase diesel fuel economy. This is likely a result of reduced deposits on engine components resulting from biodiesel use.
  
• Some users also have experienced reduced engine wear and successful extension of oil change intervals.
