Biodiesel

Biodiesel has been in use by the University of Texas at Austin since September 27, 2001. B20 is composed of 80% #2 diesel and 20% biodiesel. Biodiesel is made from renewable feedstock, such as vegetable oils and animal fats, through a simple refining process. Diesel-powered vehicles require no modification to run on B20.

E85

E85 fuel is a renewable fuel that may be used in the future at the University.  It contains 85% ethanol and 15% gasoline. Ethanol is non-toxic, water soluble and biodegradable. It is produced by the fermentation of plant sugars, usually from corn or other grain products. Vehicles capable of using E85 fuel are called flex-fuel vehicles because a single fuel tank can hold any mixture of gasoline and ethanol fuel, up to 85% ethanol.

Propane

Propane, or liquefied petroleum gas (LPG), is also in use by the university. It is readily available almost anywhere in Texas. Vehicles capable of using propane fuel are required to use the fuel when it is available.
