“Average gasoline prices declined in just six states over the last week, led by the Great Lakes region, where motorists in states like Michigan and Ohio saw prices fall sharply, while Indiana experienced even steeper relief after the state temporarily waived both its excise and use taxes on gasoline. Those declines helped pull the national average lower by roughly eight cents over the last several days after oil prices eased mid-week on optimism that the U.S. and Iran could reach a deal,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
“However, that optimism has since largely unraveled, with talks appearing to stall and President Trump signaling the latest proposal is unacceptable, helping push oil prices higher again in Sunday electronic trade." he added. “As a result, many states could see another round of price cycling in the days ahead, potentially sending the national average toward the $4.65-per-gallon mark if oil continues climbing. In addition, diesel prices across much of the Great Lakes region are nearing new record highs as ongoing refinery issues continue to disproportionately impact diesel production. Should geopolitical tensions escalate further, fuel prices could rise even more sharply in the weeks ahead.”
