U.S. gas prices declined in the past two weeks, but hardly enough to provide relief for summer travelers, a nationwide survey released Sunday showed.
The average price for self-serve regular gas on Friday was down 4.5 cents to $2.89 a gallon, according to the Lundberg Survey of 7,000 gas stations across the country.
That's just 6 cents less than this year's peak price of $2.95 a gallon in early May, but still 68 cents higher than last year's average.
The average mid-grade price was $2.99 a gallon while premium ran $3.09.
Charleston, S.C., had the lowest average price of gas in the U.S., selling at $2.61 a gallon. The highest average pump price, at $3.26 per gallon, was in Honolulu.
