For the week ending July 6, 2018, the four-week average of U.S. gross refinery inputs surpassed 18 million barrels per day (b/d) for the first time on record. U.S. refineries are running at record levels in response to robust domestic and international demand for motor gasoline and distillate fuel oil.
Despite record-high inputs, refinery utilization has not surpassed the record set in 1998. Rather than higher utilization, refinery runs have increased with increased refinery capacity. U.S. refinery capacity increased by 862,000 barrels per calendar day (b/cd) between January 1, 2011, and January 1, 2018.
