“While pump prices haven’t exactly plummeted, we’ve seen the average price of gasoline drop in a majority of states over the last week as refineries finish maintenance and ramp up output of products like gasoline,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “With gas prices now nearing a 10-cent drop to the high we saw a few weeks ago, the future looks good as we get closer to Memorial Day; price drops could potentially accelerate after last week’s jobs data shows the economy continues to cool off. While gas prices stand slightly above where they were last year, I expect most Americans will see prices fall before the holiday weekend, and I’m optimistic the trend could extend into June and beyond. I’m excited to say it does appear that for now, the worst is behind us.”
