The national average price of regular unleaded has remained flat at $2.86 per gallon for the week ending Aug. 13 in which consumer demand fell and gasoline inventories increased for the first time in six weeks, according to AAA.
On the week, the U.S. Energy Information Administration reported an increase of 3 million barrels of gasoline inventory. For the week, pump prices are an average of 1 cent lower than a week ago, 3 cents lower than a month ago, and 51 cents higher than a year ago.
"With a flat national average, U.S. gasoline supply and demand suggest they are balancing," said Jeanette Casselano, AAA spokesperson. "But that’s not to say that we could not see spikes in demand closer to Labor Day as motorists squeeze in those final road trips."
