Brent crude was up 2pc at $59.48 a barrel at 0924 GMT, after falling 2.1pc on Thursday and 3pc the previous day. US crude was also 2pc higher at $55.60 a barrel, having dropped 1.4pc in the previous session and 3.3pc on Wednesday.
US retail sales rose 0.7pc in July as consumers bought a range of goods even as they cut back on motor vehicle purchases, Thursday's data showed.
That came a day after a sell-off in world markets that followed the US Treasury yield curve's first inversion since June 2007 - a development usually seen as a reliable predictor of looming recession.
"The rebound has a corrective look about it on thin volumes, rather than a beachhead for an impending rebound," said Jeffrey Halley, senior market analyst at OANDA. "Overall, US data continues to be a bright spot in a dark economic universe."
World stocks also rose on Friday as expectations grew for further stimulus by central banks, offsetting worries about slowing economic growth.
Gains are likely to be capped after a week of data releases included a surprise drop in industrial output growth in China to a more than 17-year low, and a fall in exports that sent Germany's economy into reverse in the second quarter.
"The broader story around global economic growth has been a weak one, or a weakening one, and expectations (are for) further weakening," said Phin Ziebell, senior economist at National Australia Bank.
The price of Brent is still up nearly 10pc this year thanks to supply cuts led by the Organization of the Petroleum Exporting Countries (OPEC) and allies such as Russia, a group known as OPEC+.
In July, OPEC+ agreed to extend oil output cuts until March 2020 to prop up prices.
"At what point will further output cuts be needed at the back end of this year from OPEC and Russia to keep things going the way they are?" Ziebell said.
A Saudi official indicated this month that more steps may be coming, saying Saudi Arabia was committed to do "whatever it takes" to keep the market balanced next year.
OPEC's efforts have been undermined by worries about a slowing global economy amid a trade dispute between the United States and China, as well as rising US stockpiles of crude and higher output of US shale oil.
