b100 biodiesel

Bio-diesel info?

Can anyone tell me something about biodiesel? B99, B100? Which is for cars? Any extra information is fine.

Either can be used for cars. The number after the B tells you how pure the biodiesel is. Pure biodiesel is referred to as B100. It is common to see B99, since 1% petrodiesel is sufficiently toxic to retard mold. Mold is cause by moisture in the air when the fuel is being made. Water in diesel engine is bad. Either one of these fuels are sufficient to run in a vehicle. Biodiesel can also be used in its pure form (B100), but may require certain engine modifications ( changing of hoses and tubing) to avoid maintenance and performance problems.
