Seattle Gas Prices

Seattle gas prices this week

The Seattle metro averaged $5.424 per gallon for regular gasoline in the week ending Oct 26, 2026. The metro average fell $0.100 from the previous week, and it is $0.221 above the Washington statewide average of $5.203. Against the national average of $4.269, Seattle is $1.155 more expensive.

Seattle has the highest gasoline prices in the Pacific Northwest. Washington’s cap-and-invest program adds a carbon cost to fuel, and Puget Sound refineries supply a market with limited outside competition.

What drives prices in Seattle

• The Climate Commitment Act adds a carbon allowance cost to every gallon.
• Five Puget Sound refineries supply Washington and Oregon.
• High station operating costs in Seattle and Bellevue raise retail margins.

Metro averages smooth out station-level differences, but they are still the right baseline for budgeting. A station a few blocks from a highway ramp can easily charge 20 cents more than one on a secondary road in the same county.

Areas covered by the Seattle average

The metro series includes the core city and the surrounding communities that share its fuel distribution network: Bellevue, Tacoma, Everett, Redmond, Kirkland, Renton. Prices in outlying counties can run 10 to 25 cents lower or higher depending on local taxes and distance from the nearest terminal.

Commuting cost in Seattle

Seattle commutes are moderate in distance but often slow. Hybrid and plug-in vehicles see a bigger advantage here than in most U.S. metros.

A simple benchmark: a 30-mile round trip at 28 MPG costs about $5.81 per day at the current Seattle average. Over 260 working days that is roughly $1511 per year. Use the commute cost calculator with your real mileage, and the gas mileage calculator if you are not sure what MPG your car actually returns in city traffic.

How to pay less at the pump in Seattle

1. Start with membership warehouses: Costco, Sam's Club, and BJ's typically undercut nearby stations by 10 to 30 cents.
2. Check stations one exit past your usual stop — highway-adjacent stations price for convenience, not for locals.
3. Use a station-level app for the final address; use this page to judge whether the price you see is normal for the metro.
4. Fix the cheap things first: tire pressure, air filter, and removing unused roof racks each return 2 to 6 percent of fuel economy.

How this page is built

The Seattle series is the EIA's published metro retail average, updated weekly and restated in dollars per gallon including taxes. We rebuild this page every week after the survey release and print the survey week at the top so there is no ambiguity about the date. See the methodology and data sources pages for details.
