Oregon ranks among the more expensive states, combining a 40¢ gas tax with Pacific Northwest refinery limitations and a state law (only recently changed) that historically required full-service attendants — adding labor costs. Portland prices tend to run above average; eastern Oregon is more affordable.

Oregon Gas Price FAQ
Did Oregon's full-service gas law affect prices?
Oregon only recently allowed self-service statewide (rural areas got it first in 2018, urban areas followed). The full-service requirement historically added labor costs that kept Oregon prices slightly above comparable western states.
Where is gas cheapest in Oregon?
Costco stations in Portland suburbs offer the lowest prices in the metro. Eastern Oregon cities like Bend and Pendleton are often cheaper than the Willamette Valley despite being more rural, due to proximity to different supply routes.
