- Biodegradable
- Non-toxic
- Safer to handle
|
- Use of blends above B5 not yet approved by many auto makers
- Lower fuel economy and power (10% lower for B100, 2% for B20)
- Currently more expensive
- B100 generally not suitable for use in low temperatures
- Concerns about B100's impact on engine durability
- Slight increase in nitrogen oxide emissions possible in some circumstances
