Supplies of distillate fuels, which include home heating oil, rose by 2.3 million barrels to 120 million barrels with inventories in the lower limit of the average range. Stockpiles of gasoline rose by 3.3 million barrels to 203.5 million barrels in the current week. Inventories of finished gasoline and blending components increased, the agency said.
