The average price of gasoline in the U.S. has dropped six cents over the past two weeks to $2.16 a gallon for regular grade.
Industry analyst Trilby Lundberg said Sunday that the price has dropped 21 cents since a peak June 3, though the most recent decline is slightly smaller and price drops could soon cease.
Lundberg says the average price is 55 cents lower than a year ago.
The Lundberg Survey found the average price of midgrade unleaded was $2.46 a gallon, and premium was $2.67.
The highest average price for regular gas in the contiguous U.S. was $2.70 a gallon in San Diego. The lowest was $1.81 in Jackson, Mississippi.
The U.S. average diesel price is $2.35 per gallon, down four cents from two weeks ago.
