Oil falls amid concerns about global economy

The price of oil fell Tuesday as investors weighed positive U.S. economic news against ongoing concerns about Europe.

Benchmark oil dropped 59 cents to end at $91.89 per barrel in New York. Brent crude, which is used to price international varieties of oil, fell 62 cents to $111.57 per barrel in London.

CoreLogic, a private real estate data provider, says a measure of U.S. home prices jumped 4.6 percent in August compared with a year ago. That's the largest year-over-year increase in more than six years. The new data provides more evidence that the housing market continues to improve.

But investors remain concerned about Europe's ongoing financial crisis after Spain's prime minister said a request for bailout funding isn't imminent.

Slower growth in China, which is a huge importer of oil, has also kept a lid on oil prices. Slower growth can cut demand for oil and other energy products.

At the pump, the national average for gasoline was unchanged at $3.78 per gallon, according to AAA, Wright Express and the Oil Price Information Service. That's about a nickel less than a month ago but still nearly 36 cents more than a year ago.
