The price of oil rose slightly Thursday as expectations of greater use of heating oil during extreme cold weather in North America offset signs of weak demand for gasoline, AP reported. Benchmark U.S. oil for February delivery was up 30 cents to $92.63 a barrel at 0830 GMT in electronic trading on the New York Mercantile Exchange. The contract fell $1.34 to $92.33 on Wednesday after the U.S. Energy Department said supplies of gasoline rose by 6.2 million barrels last week, a jump of nearly 3 percent. Platts, the energy information arm of McGraw-Hill, said the data indicated that demand for gasoline was the lowest in a year. Prices recovered a bit Thursday as the record-breaking cold affecting the northern U.S. boosted demand for heating oil. Brent crude, used to set prices for international varieties of crude, was up 36 cents to $107.54 on the ICE exchange in London.
