How does biodiesel compare to petroleum diesel in terms of performance?
If B20 is used, there is no noticeable difference in power and torque, however fuel economy could decrease by 1%-2%, depending on the petroleum diesel blended with. Most users report little difference between B20 and the No. 2 diesel, and as biodiesel blend levels decrease, performance differences are nearly diminished between the two. Typically, biodiesel contains 8% less energy per gallon than No. 2 diesel in the United States. This difference is caused by an 11% increase in oxygen by weight in biodiesel.
