U.S. Oil Futures End Slightly Higher

West Texas Intermediate oil futures for March delivery ended a choppy session slightly higher. Crude erased an early rally to bounce between small gains and losses after weekly government data showed a rise in inventories for U.S. crude, gasoline and distillates and Saudi Arabia's finance minister was quoted as saying the country wasn't prepared to cut production. March crude settled at $30.77 a barrel, gain of 11 cents, or 0.4%.
