For example, B20 which is a common blend for fleets and buses contains 20% biodiesel extender and 80% base diesel fuel. Pure biodiesel extender l is also referred to as B100.
Advantages of Biofuel
- Sulphur dioxide emissions can be reduced
- Additional lubricity advantages
- Often reduces unburned hydrocarbons, carbon monoxide and particulate matter in exhaust fumes
- Can improve engine performance
