BUSINESS BRIEFING / GASOLINE

Retail gas prices fell every day this week, easing off their national summer peak of $2.693 a gallon as U.S. storage facilities swelled with unused supplies.

At the pump, the national average for gasoline dropped less than a penny Friday to $2.658 a gallon, according to AAA, Wright Express and the Oil Price Information Service.

In California, the statewide average price for a gallon of regular gas fell to $3.010, down from $3.028 a week ago. The price was $2.671 a gallon a month ago and $4.596 a gallon at this time last year.

Nationally, a gallon of gas added an average of 22.4 cents in the last month as prices rose for 54 straight days. But gas is still cheaper than last year, when prices spiked above $4.
