Oil rose towards $79 a barrel on Friday, after sliding more than 2 percent the previous session, as an upwards revision in U.S. gross domestic product for the fourth quarter helped revive lacklustre sentiment.
The U.S. economy grew faster than initially thought at 5.9 percent versus 5.7 percent in the fourth quarter, a government report showed on Friday, boosting expectations for fuel demand growth in the world's top energy consumer.

$80 CEILING
Prices have traded in a range between $69 and $84 a barrel since last October, but $80 a barrel is being reinforced as a key resistance level, analysts said.

Israel lobbied the United States on Thursday to promote "crippling" sanctions against Iran to curb its nuclear programme, but the Obama administration said it did not want to hurt the Iranian people.
The market shrugged off a rise in the dollar versus the euro on Friday. A stronger dollar tends to weigh on oil as it makes it more expensive for holders of other currencies.
