Biodiesel is a cleaner burning, renewable fuel for diesel engines made from oilseed crops like canola or soybean. It can be used in existing diesel engines with no mechanical modification. Biodiesel is produced via the chemical reaction between vegetable oils or animal fats and alcohol, such as methanol, in a process called transesterification.


Pure or neat, 100% biodiesel


Pure biodiesel with which .1% diesel fuel has been blended in order to secure the federal blenders tax credit for biodiesel. Agri-based B99.9 typically sells for $1.00 less than B100 due to the federal tax credit.


A blend of pure biodiesel and petroleum diesel fuel. The percentage of pure biodiesel in the blend is identified by the numbers “XX” which follow the “B”. For example, B10 is a blend a 10% pure biodiesel and 90% petroleum diesel. B20 is a blend of 20% biodiesel and 80% petroleum diesel. Blue Sun Fusion is B20.


Agri-biodiesel is biodiesel derived solely from certain agricultural products including virgin vegetable oils from corn, soybeans, sunflower seeds, cottonseeds, canola, crambe, rapeseeds, safflowers, flaxseeds, rice bran, and mustard seeds, and from animal fats. Agri-biodiesel is eligible for the $1.00 federal blenders tax credit.
