U.S. Annual Crude Oil Consumption

According to the EIA:

 For consumption, see Product Supplied, which approximately represents consumption of petroleum products because it measures the disappearance of these products from primary sources, i.e., refineries, natural gas processing plants, blending plants, pipelines, and bulk terminals.

Only a relatively small amount of crude oil is consumed directly in the United States.  Nearly all crude oil is refined into petroleum products such as gasoline, diesel fuel, heating oil, and jet fuel, which are then consumed.  Liquids produced from natural gas processing are also consumed as petroleum products.  Renewable biofuels, such as ethanol and biodiesel, can be used as a substitute for or an additive to refined petroleum products.  EIA includes volumes of biofuels in data on total petroleum consumption.

In 2013, the United States consumed a total of 6.89 billion barrels of petroleum products, an average of 18.89 million barrels per day. This total includes about 0.32 billion barrels of biofuels.
