West Coast Region Gas Price History
The EIA does not publish weekly prices for Oregon, so this chart shows the West Coast regional average for regular gasoline, the same series behind the Oregon price above. The region also covers Alaska, Arizona, Hawaii, and Nevada, so the line describes the region as a whole, not Oregon alone. The latest week is $1.04 a gallon higher than a year earlier.

About Gas Prices in Oregon
The U.S. Energy Information Administration (EIA) surveys fuel retailers weekly but doesn't publish a separate price for Oregon, so the price shown is the EIA's West Coast regional average for regular unleaded gasoline. Prices at individual stations in Oregon may be higher or lower depending on location, brand, and local competition.
Several factors influence Oregon's gas price: state fuel taxes, the distance from major refineries, pipeline and distribution infrastructure, and the required seasonal fuel blend. Use the calculator above to see exactly how today's Oregon price affects your commute, road trip, or monthly driving budget.
Oregon Fuel Taxes: ≈40¢/gal
Oregon has a high state gas tax plus clean-fuel program costs. Oregon charges about 40 cents per gallon in state tax, and Portland adds a 10-cent city fuel tax on top. The state's Clean Fuels Program, which requires reducing the carbon intensity of transportation fuel, adds several more cents per gallon in compliance costs that refiners pass through at the pump.
Tax figures are approximate state-level taxes and fees per gallon of regular gasoline and exclude the 18.4¢/gal federal excise tax. Rates change, so verify current rates with the state's revenue or transportation department.
How Oregon Gets Its Gasoline
Oregon has no refineries. Nearly all of its gasoline comes from Washington's Puget Sound refineries via the Olympic Pipeline and by barge down the coast, so Oregon inherits Washington's supply disruptions with an extra transportation step. For decades Oregon banned self-service statewide; since 2023 drivers may pump their own gas everywhere, though attendants remain common.
Where Gas Is Cheapest and Most Expensive in Oregon
Portland is reliably the most expensive market in the state thanks to its city fuel tax and higher operating costs. The Willamette Valley runs moderately below Portland, while eastern Oregon — supplied partly from Utah and Idaho — often has the state's cheapest gas.
