School Buses on Biodiesel
The St. Johns, Michigan school district switched their entire fleet of 31 school buses to B20 biodiesel (20% bio, 80% petrodiesel) in 2002. They've now put over one million miles on them, and report better mileage (8.8 mpg compared to 8.1 previously), cleaner exhaust, fewer oil changes needed, and fewer problems with fuel pumps.
