Finding cheap gas in Seattle (98133)
Aurora Avenue North, the old Route 99, is the pump corridor here. It runs the eastern edge of Bitter Lake and Haller Lake about nine miles north of downtown, and most of the stations sit along it rather than tucked into the quiet residential blocks toward Broadview and Puget Sound. If you stay west of Greenwood Avenue North you will pass almost no fuel at all, so locals already know to drift back east toward Aurora when the tank runs low.
Washington carries one of the steepest fuel-tax loads in the country once the state gas tax and the Climate Commitment Act carbon charge are stacked on top of the federal excise, so the posted number on Aurora reflects a real tax premium, not gouging by any single station. That makes the spread between a busy high-volume station and a slow one worth chasing.
Two things move price in this stretch. Stations right at the North 145th Street line edge toward Shoreline competition, and the membership and grocery fuel a short drive away tends to undercut the standalone Aurora pumps. Checking a couple of options before you commit usually beats grabbing the first canopy you see.

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.
