NEW YORK, March 1 (Reuters) - Oil fell slightly in choppy trade on Monday as a stronger dollar pressured prices, outweighing gains on Wall Street.
The euro fell against the dollar on Monday as uncertainty remained over a bailout package for debt-strapped Greece, while Wall Street extended gains after a spurt of takeover news.
U.S. crude for April delivery <CLc1> fell 10 cents to $79.56 a barrel by 12:51 p.m. EST (1751 GMT), after climbing as much as 96 cents. On Friday, the contract settled up $1.49 at $79.66 and posted its biggest monthly percentage gain since May 2009.
London Brent crude <LCOc1> rose 2 cents to $77.61.
"Rising equities are being offset by a stronger dollar and the market lacks some direction right now," said Gene McGillian, analyst at Tradition Energy in Stamford, Connecticut.
"It looked as if we might have weathered some of the sell off last week with a little more positive economic sentiment, but today's manufacturing number helped deflate that a bit."
The U.S. manufacturing sector grew in February but at a slower rate than was expected, according to an industry report released on Monday.
The Institute for Supply Management (ISM) said its index of national factory activity declined to 56.5 in February from 58.4 in January. The median forecast of 80 economists surveyed by Reuters was for a reading of 57.5.
Investors have looked to wider economic data over the past year for signs of economic recovery and a potential rebound in energy demand.
The rise in the dollar against the euro helped pressure crude. Oil prices have often fallen this year when the dollar firms, making crude more costly for holders of other currencies. A stronger dollar can also signal investors plowing funds into safe havens and away from assets considered more risky, including commodities.
COPPER COMMODITY
Oil rallied earlier on a combination of bullish sentiment and a rise in the price of copper futures following a massive earthquake on Saturday in Chile, the top producer of the industrially indispensable metal. [
]Chile's state energy company ENAP said it was boosting diesel imports after two of its oil refineries -- Aconcagua and Bio Bio with a combined capacity of 220,000 barrels per day -- were damaged in Saturday's quake.
On Sunday a senior military official from Iran, the world's fourth-largest exporter of crude, said the country could make European nations suffer by cutting off energy supplies and could target any adversary with its missiles. [
]Iran is disputing its nuclear energy programme with the United States and its allies, who say it is aimed at developing weapons. Tehran says it is only interested in power generation and medical research.
Oil traders will look to economic reports this week, with key focus on U.S. jobless data on Friday, that should give more clues on consumer spending, and U.S. home loans on Wednesday.
Positive economic data on Friday from the United States, which saw the world's largest economy grow faster in the fourth quarter than initially thought, also helped increase investors' appetite for more risky assets, lending further support to oil.
