How to Make your Own Biodiesel!


How to Make your Own Biodiesel!

Are you running a Diesel and concerned the amount of pollution it causes? Maybe you’re even unable to get your car's smog check to pass. Perhaps you’re even looking for an cleaner alternative to conventional diesel fuel? Have you thought about using Biodiesel? What is Biodiesel anyway?

According to:

  • Biodiesel is a clean burning renewable fuel made using natural vegetable oils and fats.
  • Biodiesel is made through a chemical process which converts oils and fats of natural origin into fatty acid methyl esters (FAME). Biodiesel IS NOT vegetable oil.
  • Biodiesel is intended to be used as a replacement for petroleum diesel fuel, or can be blended with petroleum diesel fuel in any proportion.

What are some of the benefits compared to petroleum diesel fuel?

  • Biodiesel has reduced exhaust emissions compared to petroleum diesel fuel.
  • Biodiesel has lower toxicity compared to petroleum diesel fuel.
  • Biodiesel is safer to handle compared to petroleum diesel fuel.
  • Biodiesel quality is governed by ASTM D 6751 quality parameters.
  • Biodiesel is biodegradable.



Biodiesel is much safer for your diesel than say, vegetable oil. There are several environmental advantages to using biodiesel over petroleum diesel (ie fossil fuel). It causes much less damage in production than fossil fuel extraction – it is biodegradable, non-toxic, and essentially free of sulfur and aromatics. Biodiesel also has much better lubricity than petroleum based diesel.

According to:

Low lubricity diesel fuel may cause high wear and scarring whereas high lubricity fuel may provide reduced wear and longer component life. Biodiesel fuel blends offer significantly higher lubricity than conventional diesel; a B2 biodiesel blend (conventional diesel with 2% biodiesel) can provide up to a 65% improvement in lubricity.

Caution is advised when first using biodiesel, as it has a solvent effect on the fuel system and motor that can clear accumulated deposits and clog the fuel system. It is recommended to have a one or two spare fuel filters, change the first one after a few miles of driving (or at least be ready to do so at any time. (It is a good idea to learn how to change your own fuel filter.) Carry a spare fuel filter in the car with you and be to change it when needed at the first sign of loss of power.

After a one or two filter changes, you should be good to go. Also, some engines may need a little modification to use biodiesel, while others don’t, it’s a good a idea to check before using it for the first time.

If you don’t want to go through the making process, there are a number of retail sources to buy biodiesel. A helpful map is found HERE –
