B20 Biodiesel is an alternative fuel created by mixing regular petroleum diesel, refined from crude oil, with a biofuel produced from agricultural products such as soy beans, grape seeds and mustard seeds, or from waste cooking oils and other organic products. The B number indicates the percentage of biofuel. That means B20 Biodiesel is a blend of 20 percent biofuel and 80 percent petroleum diesel. Although biofuels can be used at any mixture, including 100 percent biofuel, the B20 mixture is considered the best blend for normal use in conventional diesel engines.
E85 is a motor fuel blend consisting of 85% ethanol and 15% gasoline (the winter blend is actually 75% & 25%). It is classified as an alternative fuel by the U.S. Department of Energy. Besides having superior performance characteristics, ethanol burns cleaner than gasoline. It is a completely renewable, domestic, environmentally friendly fuel that enhances the nation's economy and energy independence.

E85 is for use only in flexible fuel vehicles (FFVs). An FFV is designed to burn E85, but can run on regular unleaded gasoline if E85 is unavailable. The city currently has a large number of sedans, pickups, and SUVs that are designated as FFVs.
