Gasoline prices in Maryland dropped by an average of 4 cents a gallon in the last week, according to AAA Mid-Atlantic, as motorists continued to enjoy a summer of relative stability at the pumps.

AAA reported Sunday that the average price of regular gas dropped to $2.65, 6 cents below the national average. That is 9 cents higher than last year at this time but well below the peak of more than $4 a gallon reached in summer 2008.

Prices have remained stable through the summer, with the national average ranging between $2.70 and $2.78 since Memorial Day, AAA said. The group reported that crude oil prices have declined nearly 10 percent so far this month, hinting at possible further declines at the pump in the coming weeks.
