Oregon Gas Prices This Week

In the EIA’s July 2026 (revised August 2026) table of motor fuel taxes, Oregon’s state taxes and fees on gasoline total 40.0¢ a gallon, the 13th-highest of the 50 states and D.C. The 51-jurisdiction average is 33.8¢, and the federal tax adds 18.4¢ everywhere. All of it is a 40¢ excise tax, the result of a 2017 transportation law that raised the rate in steps through 2024. A further increase passed in 2025 was rejected by voters in a referendum. Counties and cities may add local option taxes, which the EIA figure excludes.

Oregon has no refineries. Most of its gasoline comes from the Puget Sound refineries in Washington, by the Olympic Pipeline to the Portland area and by barge, and is distributed from Portland terminals. Oregon also runs a Clean Fuels Program that requires the carbon intensity of transportation fuels to decline over time.

Oregon was among the cheaper states through the mid-1980s, ranking as low as 4th in 1976 and 1983. In 1992 its annual average moved from 2.6¢ above the U.S. figure to 13.4¢ above, and its rank from 29th to 47th. It has ranked 39th or higher in every year since, and 45th or higher in all but 4 of them, peaking at 50th in 1999. The gap averaged 14.8¢ in the 2000s and 29.9¢ in the 2010s.

Since 2011 the EIA has estimated Oregon’s price by applying the West Coast regional trend (excluding California) to its 2010 level; the region includes neighboring Washington, whose prices set much of that trend. The gap was 86.9¢ in 2022 and 86.8¢ in 2023. Oregon’s highest nominal average is $4.76, in 2022, which comes to $5.24 in 2025 dollars; its inflation-adjusted record is 2012, at $5.26. The lowest inflation-adjusted year was 1998.

The regional weekly series bottoms out in January, about 10.7% below the annual average, and peaks in June, 6.5% above.

The largest one-year rise in Oregon's annual average was 36.4%, in 1980, when the price reached $1.22 and the state ranked 16th-cheapest. The largest one-year fall was 25.8%, in 2009. In 1970 the average was $0.35, tied for 18th-cheapest.

Tied for 32nd-cheapest at $1.18 in 1990, Oregon ranked 48th-cheapest by 2000, when the average was $1.63. Its 2010 average of $2.90 and its 2024 average of $4.06 both ranked 47th-cheapest, and its 2020 average of $2.74 ranked 48th-cheapest. In 2024 the 47th-cheapest place was also 5th-most-expensive.

Counting 1970 through 2024, Oregon averaged below the U.S. figure in 14 of 55 years and above it in 41 of 55. The 2024 average was 77.2¢ above the U.S. figure of $3.29. Measured in constant 2025 dollars, the 2024 figure is $4.17.

Among the states bordering Oregon, California had the highest 2024 average at $4.42 and Idaho the lowest at $3.35. Oregon averaged 36.2¢ below California in 2024. It also averaged 0.8¢ below Washington ($4.07). It averaged 10.2¢ above Nevada ($3.96) and 71.3¢ above Idaho. In 2024, 2 of 4 bordering states averaged less than Oregon.
