US oil refineries operated at 95.3 percent of their operable capacity during the week ending June 5, 2026, one of the highest utilization rates of the year, according to data in the Energy Information Administration weekly petroleum status report. The strong run rate reflected refiners pushing output to meet summer fuel demand.

Crude oil refinery inputs averaged 17.0 million barrels per day during that week, an increase of 80,000 barrels per day from the prior week's average. The gain marked a continued ramp in throughput as the driving season got underway and refiners worked to rebuild fuel supply.

The June 5 figures rose from the week ending May 29, when refineries operated at 94.7 percent of available capacity and processed an average of 16.9 million barrels per day, down 90,000 barrels per day from the week before that. The week-over-week swing showed how quickly refinery runs can shift in response to maintenance schedules and margin conditions.

High utilization keeps fuel supply flowing, but it also leaves little spare capacity to absorb an unplanned outage. With refineries already running above 95 percent, any storm-related shutdown or equipment failure along the Gulf Coast or in the major refining districts could tighten diesel and gasoline supply quickly during the peak demand months.
