Biodiesel Resource

According to the U.S. Department Of Energy, using biodiesel instead of petroleum diesel drastically reduces emissions of carbon dioxide (CO₂), hydrocarbon (HC), and particulate matter (PM). Studies by the USDOE show that using B100 reduces CO₂ emissions by 78% and using B20 reduces CO₂ emissions by 15.66%.

Please make sure you consult reliable resources, such as Sundays Energy, when researching biodiesel. Many websites pertaining to biodiesel exist, so please double check any and all information.

There are no negative effects of biodiesel on a car’s engine and components (please read the disclaimer regarding questions about fuel filters). Because of the risk of topsoil erosion that may result from over-farming, biodiesel production needs to be thought of as one important part of the U.S. energy solution, not the only part. Depending on the ability of the U.S. and other countries to manage their long-term renewable energy strategies, biodiesel can serve a valuable function well into the future.

Yes. The American Society for Testing and Materials (ASTM) has approved a provisional standard for biodiesel (ASTM D 6751). Every batch of biodiesel produced undergoes rigorous testing to meet these standards. A Certificate of Analysis (COA) guarantees the testing process and accompanies the end product. More information can be found at www.astm.org

Yes. Like petroleum diesel, biodiesel can gel and cloud at temperatures below 40 degrees Fahrenheit. Lower blends such as B20 are commonly used during colder weather.

Biodiesel can be used in its pure form or be blended with petroleum diesel at any ratio. B100 is 100 percent biodiesel. B20 is 20 percent biodiesel and 80 percent petroleum diesel.

In general, Biodiesel can be stored and handled with the same procedures as petroleum diesel. Storage tanks should not be comprised of copper, brass, lead, tin, zinc, or natural rubber. Aluminum, steel, fluorinated polyethylene, fluorinated polypropylene and Teflon are all suitable for biodiesel storage. As with many fuels, biodiesel should be used within 6 months.

According to the U.S. Departments of Energy and Agriculture, 3.2 units of energy are gained for every 1 unit of fossil energy used to make biodiesel. This accounts for planting and harvesting of feedstock, production of biodiesel fuel, and transportation of the fuel to end-users.

Although biodiesel has a lower energy content than petroleum diesel, most users report little noticeable differences in power, engine efficiency, or torque.

Generally, engine manufacturers identify which fuel is recommended for use on their engines. Manufacturer warranties cover defects in material and workmanship, and those warranties extend to engines burning biodiesel. Using biodiesel will not void warranties.
