The price of oil extended gains Thursday, a day after rising for the first time in a week on signs of increased U.S. demand for gasoline and other fuels, AP reported. Benchmark U.S. crude for April delivery was up 27 cents to $100.64 a barrel at 0745 GMT in electronic trading on the New York Mercantile Exchange. The contract, which expires Thursday, gained 67 cents to $100.37 the day before. Most trading has moved to the May contract, which was up 11 cents at $99.28 a barrel. The U.S. Energy Department said that demand for gasoline rose 1.5 percent over the four-week period ended March 14 compared with the same period last year. Supplies of distillates, which include heating oil and diesel, fell by 3.1 million barrels, more than three times the decline analysts were expecting. Both figures were seen as signs of strengthening demand. Brent crude, used to set prices for international varieties of crude, was up 16 cents at $106.01 a barrel.
