The national average gas price declined for the second straight week, down 8.8 cents to $4.48 a gallon Monday. The national average is up 28.3 cents from a month ago and $1.79 per gallon higher than a year ago. The national average diesel price declined 2.7 cents in the last week, to $5.79 per gallon. Gas Buddy’s Patrick De Haan says, “gas prices have continued to fall for the second straight week as the price of oil has faltered, ushering in the drop we’re seeing.” De Haan says prices could fall again this week, even ahead of the Independence Day holiday weekend. However, any sudden jolts to supply could quickly cause a turnaround, and the risk remains that when the peak of hurricane season arrives, prices could spike again. According to GasBuddy, U.S. retail gasoline demand rose last week, up 1.6 percent compared to the prior week. U.S. crude inventories remain 14 percent below the five-year average.
