West Texas Intermediate (WTI) crude futures rose 6 cents to $53.68 a barrel.
Front-month WTI prices settled down for a sixth straight session on Tuesday, their longest losing streak this year, after U.S. manufacturing activity dropped to a 10-year low as U.S.-China trade tensions weighed on exports.
