Industry survey shows US gas prices have fallen another 12 cents a gallon over past 2 weeks

A national survey reveals the average price of regular gasoline has plunged another 12 cents a gallon over the past two weeks, to $2.72.

Industry analyst Trilby Lundberg said Sunday that the decline continues a nationwide trend.

Lundberg says lower crude oil prices are continuing to drive prices down, along with an abundant oil supply and the rising value of the U.S. dollar.

The highest-priced gas in the Lower 48 states was found in San Francisco at $3.04 a gallon. The lowest was in Albuquerque at $2.38 a gallon.

California's lowest average was in Sacramento, $2.80 a gallon.

The average price for midgrade gas in the U.S. is $2.96. For premium it's $3.12.
