City of Ann Arbor, Michigan:  For the past five years, Ann Arbor’s 120-vehicle diesel fleet has been running on B20 in the winter and moved up to B50 in the summer for the past two years. 

According to Energy Coordinator Dave Konkle “we followed the University of Michigan’s lead in going to B20 which has become quite a success story here in Ann Arbor.  We made the switch because we are an environmental community concerned about global warming and air quality issues.  Plus biodiesel smells better and runs quieter.”
