“The national average is nearly unchanged from a week ago, with gasoline prices continuing to hover in the same territory where they’ve spent much of 2025 so far—in the low-$3-per-gallon range—as oil prices remain anchored in the $60s,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Price cycling markets once again led the biggest weekly price changes, with Ohio and Florida seeing a cycle and higher prices last week, while Michigan posted the largest drop and could be due for another jump in the cycle sometime this week. For the majority of motorists in non-cycling states, gas prices will likely remain near current levels as we head toward Labor Day. However, it’s worth watching developments around a potential peace deal between Russia and Ukraine. If such an agreement materializes, it could send oil prices lower on expectations that sanctions against Russia might be eased, effectively boosting global oil supply.”
