“It’s been another relatively quiet week for average gas prices, with most states seeing modest or slight declines, while a handful of price cycling states experienced the most noticeable fluctuations,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Oil prices continue … in the mid-to-upper $60s, and with gasoline demand starting to ease as we head into August, we could see prices gradually decline as we approach Labor Day. That said, this is also the time of year when the tropics begin to stir, so we’ll be keeping a close eye on hurricane activity that could disrupt supply and shift the outlook.”
