About gas prices in Washington
Washington's gas tax sits around 49 cents per gallon, third-highest in the nation, plus the state's Climate Commitment Act adds a few additional cents to fund emissions reductions. Refining capacity is concentrated in the Anacortes-Cherry Point corridor north of Seattle, and the state is part of PADD 5 (West Coast), which often experiences supply tightness due to limited pipeline connections to Midwest fuel. Costco (founded near Seattle), Sam's Club, Fred Meyer, and Safeway fuel are the most reliable for value across the Puget Sound metro and Spokane.
