Biodiesel is an alternative fuel similar to conventional or ‘fossil’ diesel. Biodiesel can be produced from straight vegetable oil, animal oil/fats, tallow and waste .
If your car was made prior to 1993, the rubber fuel lines will probably have to be replaced. One of the major advantages of using biodiesel is the fact that it can be used in existing diesel engines without negative impacts to operating performance. Biodiesel is the only alternative fuel for heavyweight vehicles that does not require any special injection or storage modifications.
The U.S. Department of Energy explains in its Biodiesel Handling & Use Guide: “Federal law prohibits the voiding of a warranty just because biodiesel was used. The biodiesel would need to be shown as the cause of the failure. If an engine experiences a failure caused by biodiesel use (or any other external condition, such as bad diesel fuel), the damage will not necessarily be covered by the OEM’s warranty.”
No, biodiesel can only run in conventional compression-ignition (diesel) engines!
Yes, you can use biodiesel and diesel fuel interchangeably, as well as blended.
Biodiesel is a solvent. It will clear many diesel deposits that have accumulated in your fuel tank. This may cause initial fuel filter clogging but continued use of biodiesel will not cause an increased frequency of filter changes.
Yes, biodiesel can actually extend the life of your engine. Biodiesel has superior lubricating properties that reduce the wear of vital engine parts.
Using biodiesel instead of petrodiesel will significantly reduce unburned hydrocarbons, carbon monoxide, and particulate matter from tail pipe emissions. It will also virtually eliminate sulfur oxides and sulfates which are major contributors to acid rain. Nitrogen oxide emissions may slightly increase, but can be remedied with newer low-emission diesel engines.
Pure biodiesel, B100 (100% biodiesel) does not contain petrodiesel. Biodiesel can be blended with petrodiesel and is frequently sold as B20 (20% biodiesel, 80% petrodiesel blend) or B5 (5% biodiesel, 95% petrodiesel blend).
