Shipments to gas stations before certain holidays affect gasoline product supplied
U.S. holiday weekends associated with increased driving, such as Labor Day and Memorial Day, often result in large swings or changes in gasoline product supplied. EIA uses product supplied as a proxy for U.S. gasoline consumption. Some of the largest weekly decreases in gasoline product supplied often occur during the weeks of these holidays, reflecting the timing of shipments to retail gasoline stations.
