Oil fell to its lowest level in five weeks on Wednesday as more signs of a slowing U.S. economy raised concerns about demand for everything from gasoline to natural gas used to cool homes. Benchmark West Texas Intermediate crude dropped $1.86 to settle at $91.93 a barrel on the New York Mercantile Exchange. In London, Brent crude fell $3.23 to settle at $113.23 per barrel on the ICE Futures exchange. Economic data released Wednesday showed fewer U.S. factory orders, a slowdown in the service industry and rising supplies of crude and gasoline. That's pushing down the price of oil, AP reported. The Institute for Supply Management said the service industry, which employs nearly 90 percent of America's work force, in July experienced its weakest growth in 17 months. The trade group's index covers a range of companies in health care, retail, financial services and other areas. The Commerce Department said factory orders fell 0.8 percent in June. It's the second time in three months that demand has weakened. And the Energy Department said supplies of crude oil, gasoline and distillates - which include heating oil and diesel - rose last week. Wholesale demand for gasoline over the four weeks ended July 29 - the traditional height of the heavy summer driving season - was 3.6 percent lower than a year earlier, averaging early 9.1 million barrels a day. The weekly report on retail gas consumption from MasterCard SpendingPulse showed demand was down for the 19th straight week. "While gasoline can be a reflection of economic activity and outlooks, it can also be a leading indicator," Cameron Hanover said. "If that is the case here, it is not a pretty picture." Ritterbusch said he expects the price to fall by about a nickel by the end of next week as gasoline futures decline. In other Nymex trading for September contracts, heating oil fell 7.27 cents to settle at $3.0189 per gallon, gasoline futures lost 10.6 cents to settle at $2.9313 per gallon and natural gas dropped 6.5 cents to settle at $4.090 per 1,000 cubic feet. -- SPA
