HOUSTON (AP) -- Retail gasoline prices have dropped a nickel this week across Texas.

AAA Texas on Thursday reported the average price per gallon at the pump has slipped to $3.28 per gallon.

Gasoline prices declined 6 cents this week nationwide, to settle at $3.47 per gallon.

The association survey found that drivers in El Paso are paying the highest average price in Texas, at $3.46 per gallon.

The least expensive gasoline in Texas was found in Fort Worth, at $3.22 per gallon.

Experts say lower crude oil prices and economic concerns have contributed to a decline in retail gasoline prices for several months.
