With more people turning towards alternative fuel sources, B20 biodiesel is becoming more common. While it is more environmentally friendly and efficient to run on, there are several things to consider before switching your vehicle to biodiesel.
Even though biodiesel is becoming more popular, the standards for biodiesel aren't as strict as they are for gas. The biodiesel needs to be blended correctly. Most stations that offer biodiesel will purchase B100 (which is pure biodiesel) and blend it directly at the station. Unless you are aware of the method of blending, you may not end up with B20 by the time the process is complete.
Biodiesel requires a specific type of storage. Since it's made with vegetable products, temperatures must be maintained accurately. A warm tank will result in mold growing, and too cold will thicken the product making it difficult to dispense. Many stations feel that this is not worth the trouble until the product becomes more popular. It's also simply more expensive, making it less than attractive for stations who haven't seen a demand for it.
There is some debate about how biodiesel will affect an engine. While most experts agree that biodiesel will not harm a diesel engine, not all engine manufacturers are willing to follow this side. The majority of engine makers will warranty their engine if biodiesel is used, but a few do not. Before you consider using a biodiesel blend it's a good idea to check with your engine manufacturer to be on the safe side.
