In 2011, the U.S. exported more petroleum products than it imported for the first time in over six decades, according to the Petroleum Supply Monthly February report by the U.S Energy Information Administration (EIA). Petroleum products were ranked second in value, behind vehicles, of all U.S. exports during 2011 at $111.1 billion—up 60% from 2010— according to U.S. Department of Commerce trade data.
