Americans can expect gasoline prices to drop as school buses start rolling through neighborhoods across the country.

With most family vacations wrapping up and teen drivers going back to class, gasoline demand will wane and prices should fall after Labor Day. One expert says prices could drop as much as 15 cents a gallon.

The average retail price for a gallon of unleaded regular gasoline was $2.724 a gallon Friday, according to AAA, Wright Express and Oil Price Information Service. It has dropped about 4.6 cents in the past week but is still 10 cents more than it was a year ago.

Over the next month, motorists could see prices fall 10 cents to 15 cents a gallon unless there's a sudden increase in oil prices and in investors' confidence in the global economy, predicted Tom Kloza, chief oil analyst at Oil Price Information Service. Oil prices have dropped about $7 per barrel over the past two weeks as economic data signal a slowing economic recovery.
