“More states saw average gasoline prices decline than rise over the last week, with diesel falling approximately 5 cents per gallon nationally,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “On the policy front, the Trump administration’s proposed diesel deal raises more questions than it answers, and I remain skeptical that it will deliver significant relief to the trucking industry and consumers who depend on diesel. Meanwhile, Hurricane Isaias has passed, but we are awaiting updates on two refineries that were in its path, the outcome of which could impact the supply picture in the days ahead. For now, the trend is cautiously in the right direction for motorists, but between hurricane season and continued geopolitical uncertainty, it is far too early to declare the pressure on fuel prices resolved.”
