Posted in: * Alternative Fuels * Green Myth-Busting * B100 * B20 * Biodiesel * biodiesel myths facts * green myth-busting Some added info for “MYTH: Biodiesel will cause a noticeable power decrease.” This can vary based on individual engines. Biodiesel burns at a slightly different rate and temperature than regular diesel. This can alter engine characteristics slightly. Some modern engine computers can adapt for this difference and you will see almost no difference in power and torque. Other engines may not, and that is where you will notice the small percentage decrease. There have been people who have tuned their engines specifically for biodiesel and actually seen increases in torque and power output based on the longer burn cycle of biodiesel. What I have read mostly points out that it very much depends on the engine. In my personal experience with a 2005 Jeep Liberty CRD and a 2002 Volkswagen TDI is that the added lubrocity of the fuel offsets the loss in power somewhat, and B20 is indistinguishable. B100 I can tell, but my wife can’t. If you are in the Portland, Oregon metro area I have set up a map of places to buy biodiesel. I keep it updated: http://www.pdxbiodiesel.org * reply clarification: “MYTH: Biodiesel will wreck your engine.” “Over time, because it’s such a good solvent, biodiesel can degrade rubber fuel lines and gaskets. Most post-1990 vehicles don’t have rubber lines and gaskets, but some older vehicles do.” Biodiesel only affects a very specific type of rubber, namely “nitrile”. Cars made since about 1993 or so do not use “nitrile” rubber, and most older cars can easily have their lines swapped. Most of the new applications use “viton” rubber which biodiesel does not affect adversely. * reply
