“Average gasoline prices fell in a majority of states over the last week, though a fresh spike in the Great Lakes driven by a regional refinery issue nearly offset the broader decline, with that situation now beginning to clear up,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Diesel edged modestly higher nationally, and with the national average for gasoline likely to remain above $4 per gallon and diesel above $6 heading into the U.S. election, the relief motorists and policymakers have been hoping for remains elusive — even as states have moved to cut fuel taxes and the Trump administration has pulled virtually every lever available. Oil eased somewhat in Sunday trading, with WTI hovering just above $102 per barrel and Brent near $115, as markets weighed continued Strait of Hormuz uncertainty against OPEC’s latest demand revisions.”
