"With the kids back in school we're now at that point when gasoline demand eases and refineries also return to the cheaper 'winter- blend' gasoline which should start reaching consumers later this week," said Gregg Laskoski, senior petroleum analyst for GasBuddy.

"The national average price of a gallon of gas remains 20 cents lower than the average we saw a year ago, and, coincidentally, the price of the benchmark WTI that opens this week ($46/bbl) is almost identical to where it was a year ago... all  of which aligns with the seasonal retail price decline," he added.
