The U.S. government reported Friday that retail sales rose 1.1 percent in September, the biggest gain in seven months.

Crude has jumped about 17 percent from $75 earlier this month amid growing optimism that European leaders will unveil a convincing plan next week to contain the region's debt crisis.
