“Gasoline and oil prices have set new yearly highs as the imbalance of supply and demand may begin to shift as global oil production shows signs of slowing and gasoline demand is accelerating. While oil inventories in the U.S. remain well-supplied for now, they are likely to start receding as refiners begin throttling up their operations after maintenance season,” said Patrick DeHaan, a Chicago-based senior petroleum analyst for GasBuddy. “Americans appear ripe to consume near record levels of gasoline, if not the highest levels ever this summer with some of the lowest summer prices seen in ten years or so.”

Gasoline prices in all 50 states saw a rise over the last week, an average of over 8 cents.

“While we may not see as such a sharp rise this week, we aren’t out of the woods just yet. Gasoline prices may continue inching up until Memorial Day - a major test if refiners are well-prepared for the summer driving season,” DeHaan added.
