NEW YORK, Feb 1 (Reuters) - Oil rose on Monday as stronger U.S. manufacturing data prompted optimism about economic recovery and a weaker dollar helped boost crude demand after oil prices fell to five-week lows on Friday.
An industry report showed the U.S. manufacturing sector grew in January at a faster rate than expected, in a sixth straight month of expansion. The Institute for Supply Management (ISM) index rose to its highest since August 2004, a sign the world's top economy is recovering from the deepest recession in decades, which could boost oil demand.

]U.S. crude for March delivery <CLc1> rose 90 cents to $73.79 a barrel by 11:46 a.m. EST (1646 GMT). Prices touched $72.43 on Jan. 29, their lowest level since Dec. 21. London Brent crude <LCOc1> rose 87 cents to $72.33.
Oil prices fell more than 8 percent in January, pressured by weak energy demand in the United States, worries about fiscal turmoil in smaller euro zone countries and a stronger U.S. dollar.
A weaker dollar and firming equities markets helped to push oil prices higher on Monday, as optimism surrounding a U.S. recovery prompted investors to funnel more money into assets considered riskier, such as commodities and stocks. [
] [ ]"The (oil) market flushed out strongly last week, but now we are starting to see some support for prices," said Gene McGillian at Tradition Energy in Stamford, Connecticut. "The ISM number, a rise in equities and the dollar's slight weakening all support oil prices."
Oil prices often rise when the dollar weakens since it makes the dollar-priced commodity cheaper for holders of other currencies, boosting demand.
The dollar came under pressure on Monday after news that U.S. President Barack Obama expected the U.S. budget deficit would soar to a record in 2010. [
]U.S. stocks rose after Exxon Mobil <XOM.N>, the largest U.S. oil company, reported on Monday a better-than-expected 23 percent decline in its fourth-quarter profit. [
]Royal Dutch Shell <RDSa.L> said on Sunday it had shut in some crude production in Nigeria, a key African exporter, after a crude oil pipeline was sabotaged over the weekend.
A spokesman for Nigeria's main militant group MEND said in an email to Reuters that the group wasn't directly responsible for the pipeline outage, which came a day after MEND called off a three-month-old cease-fire and threatened to unleash "an all-out assault" on Africa's biggest oil and gas industry. [
]Analysts warned any rebound in oil prices could be short-lived, since demand for crude in the United States still has not rebounded strongly since the recession, prompting the U.S. refining industry to run its plants near the lowest rates since the 1980s.
U.S. stocks of distillate fuel, such as heating oil and diesel, were 16 percent above five-year averages in late January, according to government data.
"This is not a trend higher but a reaction after three weeks of falls. The fundamentals have not improved. The market is still over supplied and demand is not there yet," said Eugen Weinberg, commodities analyst at Commerzbank in Frankfurt.
