Expert Analysis
“Average gasoline prices fell in slightly more than half of states over the last week, with the Great Lakes seeing the largest declines after a major refinery successfully restarted, while the West Coast moved in the opposite direction as refinery snags there sent prices jumping significantly,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
“Diesel in the Great Lakes should also begin easing, though that relief may take several more days to materialize. With oil holding below $100 per barrel, many Americans may see modest declines ahead for gasoline and slight drops for diesel, but the West Coast faces continued pressure with further increases possible. The broader geopolitical situation remains fluid and could push prices in either direction with little warning, and with Trump still weighing a diesel export ban, impacts could follow.”
