Gas prices in Oregon climb, national average dips by a cent

OREGON (KTVZ) -- Average gasoline prices in Oregon increased 0.7 cents per gallon in the last week, reaching an average of $5.27 per gallon today. This is according to a GasBuddy survey of 1,307 stations across Oregon. The national average price of gasoline has fallen one cent per gallon in the last week, currently averaging $4.47 per gallon today.

Prices in Oregon are 32.2 cents per gallon higher than a month ago and stand $1.37 per gallon higher than a year ago. The national average is up 45.2 cents per gallon from a month ago and stands $1.33 per gallon higher than a year ago. The national average price of diesel decreased 0.5 cents compared to a week ago and stands at $5.618 per gallon.

Patrick De Haan, head of petroleum analysis at GasBuddy, provided insight into the factors affecting fuel prices. "The national average price of gasoline spent much of last week drifting lower after jumping early in the week as oil prices softened on hopes that diplomatic progress between the U.S. and Iran could help ease supply concerns," Haan said. "However, that optimism faded after President Trump's meeting with China's Xi Jinping failed to produce a breakthrough on Iran, while renewed warnings toward Tehran have helped push oil prices higher again."

Haan added that global oil inventories are trending toward historically tight levels, making markets extremely sensitive to geopolitical developments and potential supply disruptions.

Historical gasoline prices in Oregon and the national average on May 18 over the last five years include: $3.90 per gallon in Oregon (U.S. Average: $3.14 per gallon) in 2025.

The national average gasoline price data is compiled from more than 11 million weekly price reports covering more than 150,000 gas stations across the country.

Gasoline and diesel prices are likely to remain volatile. With Memorial Day approaching, any sustained increase in oil prices could begin pushing retail fuel prices higher again in the weeks ahead, according to Haan.
