Refinery utilization, measures how much crude oil refineries are processing or “running” as a percentage of their maximum capacity. It tells us roughly how much of our refining muscle is being put to work manufacturing fuel. American refineries are running full-out, at about 95% of total capacity, contributing more fuel—gasoline, diesel, jet fuel, etc.—to the global market than any other country. In fact, U.S. refineries process more crude oil every day than the United States produces, and we make more finished fuels than the United States consumes.
