NEW YORK, Feb 2 (Reuters) - Oil rose over 3 percent to top $76 a barrel on Tuesday, gaining for the second session on optimism surrounding economic recovery and weakness in the dollar.
U.S. crude oil futures <CLc1> rose $2.50 to $76.93 a barrel by 12:51 p.m. EDT (1751 GMT).
ICE Brent <LCOc1> rose $2.61 to $75.72.
"The economic data has been pretty good and petroleum markets got a cue to correct," Andrew Lebow, analyst at MF Global in New York.
Wall Street rose for the second day after positive earnings reports from economic bellwether companies United Parcel Service and Emerson Electric. [
]The S&P 500 is up for a second straight day after falling 6.2 percent in the last three weeks of January.
The dollar index dipped by midday, supporting oil prices. [
]Monday's news that 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, continued to bolster oil prices as well. [
]Also supportive was news that China's appetite for foreign oil will stay near record levels in coming months due to a recovering economy, rising refining and stockpiling capacity. [
]Despite optimism for oil demand, inventories of oil and refined products remain high.
The market is awaiting two sets of weekly U.S. oil statistics due out later on Tuesday from an industry group and on Wednesday from the government.
Analysts in a Reuters poll expect the data to show falls in crude and middle distillate inventories, including heating oil, and an increase in gasoline stocks. [
]Although U.S. oil data is forecast to show weekly drops, the absolute inventory volumes of refined products are likely to remain much above year-earlier levels.
Analysts polled by Reuters also indicated that refinery utilization rates would remain at 78.5 percent of capacity, the lowest rate in about two decades, not counting hurricane shutdowns.
Sluggish fuel demand has forced refiners to cut back on production and in some cases, shut plants.
Oil major BP Plc <BP.L> reported a loss in its downstream sector on Tuesday with refining margins at a 15-year low due to weak demand for fuels.
In an interview with Reuters Television, BP chief executive Tony Hayward said margins will likely be pressured by surplus refining capacity for some years to come. [
]On Monday, top U.S. oil company Exxon Mobil Corp <XOM.N> also reported losses due to dismal refining margins and U.S. Sunoco Inc <SUN.N> will permanently shut down a part of its refining capacity. [
