Biodiesel Compared to Petroleum Diesel

Advantages	Disadvantages
Domestically produced from non-petroluem, renewable resources Can be used in most diesel engines, especially newer ones Less air pollutants (other than nitrogen oxides) Less greenhouse gas emissions (e.g., B20 reduces CO2 by 15%) 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
