DALLAS — The average price for regular gasoline fell 5.56 cents a gallon in two weeks to $3.7394 a gallon on Friday, according to Lundberg Survey Inc.
The survey covers the period ending March 8 and is based on information obtained at about 2,500 filling stations by the Camarillo, Calif., company.
The average has risen about 48 cents since Dec. 21, 2012, and is about 8 cents below the year-earlier price of $3.8148 a gallon.
‘‘After nine weeks of prices increasing we have a drop,’’ Trilby Lundberg, president of Lundberg Survey, said Sunday. ‘‘We can expect more price cutting in the future, possibly more than a dime.’’
‘‘Both refinery margins on gasoline and retailer margins on gasoline appear healthy enough to allow for further price cuts,’’ she said.
Gasoline futures on the New York Mercantile Exchange rose 12.39 cents, or 4 percent, to $3.2035 a gallon in the past two weeks.
Futures have climbed 14 percent this year, making gasoline the second-best performer on the Standard & Poor’s GSCI index of 24 commodities after cotton.
US gasoline stockpiles fell 616,000 barrels in the week ended March 1 to 227.9 million, the lowest level in nine weeks, according to data from the Energy Information Administration.
Refineries ran at 82.2 percent of capacity, the lowest level since March, amid breakdowns and seasonal plant maintenance.
