The U.S. Energy Department weekly report showed a decline in U.S. gasoline stocks, raising worries that refiners don''t have an adequate inventory cushion before the peak summer driving season. The decline, the seventh in a row, pushed gasoline stocks to 4.6 % below year-ago levels, their lowest level since November. Gasoline inventories typically decline at this time of year as refiners shut down their plants to perform maintenance before the summer driving season. |
