Whats the difference between B100, B99 and B20?
B100 is biodiesel. B20 is a blend of 80% petrodiesel with 20% biodiesel. B5 is a 5% biodiesel blend with 95% petroleum diesel. B99 is essentially pure biodiesel, but has 1% petroleum in it to receive a tax break for using it as a blend. The tax break is given to the blender who then (hopefully) passes the savings down to the consumer.
