Patrick De Haan, head of petroleum analysis at GasBuddy, said average gas prices declined in 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. However, that optimism has since largely unraveled, with talks appearing to stall and President (Donald) Trump signaling the latest proposal is unacceptable, helping push oil prices higher again in Sunday electronic trade," De Haan said.
Refinery issues are disproportionately impacting diesel production, De Haan said. The national average price of diesel has increased 0.2 cents compared to a week ago and stands at $5.623 per gallon.
The national average price of gasoline has risen 5.1 cents per gallon in the last week, averaging $4.48 per gallon today. The national average is up 37.3 cents per gallon from a month ago and stands $1.40 per gallon higher than a year ago, according to GasBuddy data.
Trump said Monday that he plans to reduce the federal gasoline tax, currently 18 cents a gallon, for a yet to be determined period.
