The national average price of diesel decreased 1.4 cents compared to a week ago and stands at $5.570 per gallon.
“Average gasoline prices fell in slightly more than half of states over the last week while diesel declined in roughly half, as oil prices moved lower and offered some modest relief at the pump,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
“Over the weekend, the Trump administration struck a major deal with Venezuela, a signal that the White House remains concerned about elevated fuel prices — though in reality, any benefits from increased Venezuelan output will take years to fully materialize and are unlikely to move the needle in the near term. The factors with the most immediate impact on where prices go from here remain the ongoing developments between the U.S. and Iran and continued Ukrainian attacks on Russian oil refineries, both of which continue to exert outsized influence on global fuel markets. Motorists should expect continued volatility in the weeks ahead," De Haan continued.
GasBuddy also provided a five-year lookback for Aug. 31, showing Seattle’s average price at $4.49 per gallon in 2025, $4.36 in 2024, $5.22 in 2023, $4.91 in 2022 and $4.03 in 2021. The U.S. average on those dates was $3.15 in 2025, $3.31 in 2024, $3.79 in 2023, $3.81 in 2022 and $3.17 in 2021.
