About
Biodiesel is a domestically produced, renewable fuel that can be manufactured from feedstocks including vegetable oils, animal fats, or recycled restaurant greases. More than half of the biodiesel industry can use any fat or oil feedstock, including recycled cooking grease. The other half of the industry is limited to vegetable oils; soy oil is the most common source in the United States today.
Before using biodiesel, check your engine warranty to ensure that higher-level blends will not void or affect it. All manufacturers accept the use of B5 and many accept the use of B20.
Benefits of Biodiesel
Energy security: Biodiesel is a domestically produced, renewable substitute for petroleum diesel.
Emissions reduction: Using biodiesel reduces greenhouse gas (GHG) emissions because carbon dioxide released from biodiesel combustion is offset by the carbon dioxide absorbed while growing the soybeans or other feedstock. Using B20 reduces carbon dioxide emissions by 15%.
Convenience: Diesel-powered vehicles require no modification at all to run on 20% biodiesel mixed with regular diesel (known as B20). B20 can be stored and dispensed in exactly the same manner as petroleum diesel fuel.
Safety: Biodiesel is non-toxic. It causes less damage than petroleum diesel if spilled or released to the environment. It is safer than petroleum diesel because it is less combustible.
