How to save more on gas in Seattle
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

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.
