Oil and gasoline tumbled by the most in over two weeks after the EIA reported swelling fuel stocks and slowing demand. U.S. gasoline inventories rose 1.9 million barrels last week, the biggest gain since May, while a measure of consumption slid to the lowest since late September ahead of the sluggish winter driving months. The report also showed a fifth straight weekly build at Cushing. Still, crude supplies dropped just over 1 million barrels and distillate stockpiles fell.
