NEW YORK (CNNMoney.com) -- Gas prices fell another 2 cents, marking the fourth straight decline after rising more than 18 cents in 8 days following Hurricane Ike, according to a nationwide survey of credit card swipes at gasoline stations.

The average price of unleaded regular dropped 2 cents to $3.757 a gallon, from $3.777 a gallon, according to the survey released by motorist group AAA.

While prices have remained under $4 for some time, they are still much higher from a year ago, when gas was selling for less than $3 a gallon.

Current prices are about 34% higher from a year earlier at this time. Still, prices are 54 cents, or 13%, down from the record high price of $4.114 a gallon set on July 17

Gas prices had been moving higher following the devastation left behind by hurricanes Ike and Gustav.

More than 30 refineries, which convert crude oil into usable gasoline, had shut down or were operating with reduced capacity in the Gulf region after the storms hit. The number has since fallen by more than half, restoring gasoline supply to retailers and easing consumer prices.

Many crude pipelines in Texas and Louisiana had also shuttered ahead of the hurricanes. Those are slowly coming back on line.

Lower oil prices have also helped lower the cost of retail gas. Crude has been moving lower since mid-July amid weakening demand, losing more than a third of its value since it reached a record of near $150 just two months ago.

But oil prices rallied back above $104 a barrel Friday amid growing optimism that the government's various rescue plans will help ease the credit crisis currently stifling the U.S. economy.

Meanwhile, only three states now continue to report gas prices above $4 a gallon: Alaska, Hawaii and Illinois. Alaska continues to be the state with the most expensive gas prices, at $4.339 a gallon. The cheapest gas can be found in New Jersey, where gas cost $3.468 a gallon, according to AAA's Web site.
