How does biodiesel compare with horsepower, fuel economy, and torque?

0

Almost identical to petroleum diesel. In terms of energy contained in the fuel, a gallon of biodiesel contains slightly less energy than a gallon of petroleum diesel. This is because alcohol molecules are attached to the ends of the fatty carbon chains in biodiesel, causing them to be slightly bulkier with slightly less concentrated energy. However, the increased lubricity of biodiesel helps to counteract this energy difference. The end result is that some drivers report a slight reduction (1%) in mileage, while others report slight increases. You not notice any difference at all.
