Gas prices in Portland, OR

About gas prices in Portland, OR

Portland operates inside PADD 5 West Coast supply dynamics but with Oregon's specific market structure. No refining capacity exists in Oregon, so all gasoline arrives via pipeline (from BP Cherry Point and Anacortes WA refineries) and barge. Oregon state gas tax is around 38 cents per gallon. Oregon was historically the only state that required full-service gas stations (drivers could not pump their own fuel), though that rule was relaxed in 2023. Portland typically runs within 10 cents of Seattle. Drivers in suburbs (Beaverton, Tigard, Hillsboro) and across the Columbia in Vancouver WA (where Washington fuel tax applies) typically see 10 to 20 cents per gallon savings versus downtown Portland.
