Oil prices edged up on Friday, in thin and choppy trade, supported by hopes Greece's upcoming election will not result in an exit from the Euro zone, while weak U.S. economic data limited gains.
Both Brent and U.S. crude posted weekly losses, though the U.S. slip was only 7 cents.
Friday's gains were hemmed in by separate reports showing U.S. manufacturing output contracted in May, while factory activity slowed in New York state in June and U.S. consumer sentiment fell.
World equity markets rose on Friday as investor fears of euro zone turmoil following Greek elections this weekend were offset by talk the world's major central banks stand ready to make a coordinated response to ease any market dislocation.
The euro rebounded and U.S. stocks shrugged off a new batch of weak factory data, while U.S. consumer sentiment fell in early June to a six-month low, according to a survey.
But anxiety that Greece could fail to form a government after Sunday's elections led investors to raise their safe-haven bond holdings, driving up U.S. government debt prices.
