Changing demand for petroleum products has led to operational changes at U.S. refineries
Demand for transportation fuels in the United States has fallen since mid-March because of the spread of coronavirus and efforts to mitigate it. Demand for motor gasoline and jet fuel in particular has fallen to its lowest levels in years. In response, U.S. refineries reduced their operations to adjust to changing levels of overall demand for petroleum products and made other changes that resulted in proportionately less production of motor gasoline and jet fuel and more production of distillate fuel oil.
Beginning in April, refiners responded to less demand for transportation fuels by decreasing overall refinery runs. Refinery runs were 22% lower in April 2020 compared with the full year 2019 average of 17.0 million barrels per day (b/d). In May, inputs to distillation units were similar, at 21% lower than the 2019 average. These reductions largely resembled the overall declines in demand for finished petroleum products in those months, as measured by product supplied.
Because demand for motor gasoline and jet fuel was disproportionately affected by travel restrictions and other measures that were in place throughout much of the United States starting in late March, refineries changed operations in ways that resulted in less production of motor gasoline and jet fuel and more production of distillate fuel oil.
