| NEW YORK
NEW YORK Oil prices pushed higher on Friday, posting an eighth straight month of gains as the weaker dollar and turmoil in North Africa and the Middle East offset concerns about fuel demand and slowing U.S. economic growth.

Thursday's report that growth in the U.S. gross domestic product slowed more than expected in the first quarter reinforced the perception that the U.S. central bank will continue with its loose monetary policy.
"Yesterday's three-year lows in the dollar index following the mid-week Fed statement strongly suggests a market dynamic that is not yet ready to reverse," Jim Ritterbusch, president at Ritterbusch & Associates in Galena, Illinois, said in a note.
"Consequently, oil will continue to be valued as an asset class or inflation hedge along with other commodities such as the gold market."
Crude oil trading volumes remained tepid, dampened by a holiday in the United Kingdom.
