Patrick De Haan, head of petroleum analysis at GasBuddy, said price jumps occurred in every state this week, with the largest increases concentrated in the Great Lakes region.
“Refinery outages were a key driver behind those outsized increases, but early signs of improvement could help ease some of the most extreme price pressures in the Great Lakes in the days ahead,” De Haan said in a statement.
