The EIA said crude stocks dropped by 6.1 million barrels in the week ended Dec. 25.

The EIA said gasoline inventories fell by 1.2 million barrels, while distillate inventories rose 3.1 million barrels. Analysts surveyed by S&P Global Platts had expected gasoline inventories to show a rise of 2.3 million barrels and distillate stocks to rise by 1.3 million barrels.
