Diesel fuel is the second largest transportation fuel in California behind gasoline. In 2007, more than three billlion gallons of diesel were sold, according to the state Board of Equalization.

According to the U.S. Department of Energy's Energy Information Administraiton, "Nearly all semi-trucks, delivery vehicles, buses, trains, ships, boats and barges, farm, construction and military vehicles and equipment have diesel engines. In 2006, diesel fuel accounted for about 16% of total refined petroleum products and 77% of the total distillate consumed in the U.S. On-highway motor vehicles use about 75% of total diesel fuel, with the rest consumed by "off-highway" construction, farming equipment, military and railroad vehicles and equipment, and marine craft."
