Gas Prices in Spokane Today

If you've driven across Washington State, you already know the price drop that happens somewhere east of the Cascades. Spokane drivers are currently paying around $4.10 per gallon for regular unleaded, roughly 60 cents less than Seattle and the Puget Sound metro. For a 15-gallon fill-up, that gap puts an extra $9 in your pocket compared to what drivers on the west side pay.

Why Eastern Washington Gas Is So Much Cheaper

The east-west price divide in Washington isn't about income tax or lifestyle, it's about the supply chain and one very expensive blend requirement.

Western Washington stations sell a specialized reformulated gasoline blend mandated for the Puget Sound airshed. That blend costs more to produce and is sourced primarily from refineries clustered around Anacortes and Ferndale on the coast. Spokane, sitting east of the Cascades, is exempt from the Puget Sound blend requirement and draws fuel from different distribution infrastructure, primarily pipelines and terminals running from Portland and down through the Columbia Basin.

Washington's state gas tax is 49.4 cents per gallon, one of the highest in the country, that hits both sides of the state equally. But the blend premium, refinery proximity markup, and higher real estate costs for Seattle stations all stack on top of the base tax in western Washington. Spokane doesn't carry those additional costs.

The result: Spokane consistently ranks among the cheaper major markets in the Pacific Northwest, usually running 55–65 cents below Seattle even when statewide averages move up or down.

The Idaho Border Advantage

Here's a detail Spokane drivers know well: crossing into Idaho saves you even more. Post Falls and Coeur d'Alene stations on the Idaho side of the border routinely run 20–30 cents below Spokane prices. Idaho's state fuel tax is 33 cents per gallon, 16 cents lower than Washington's. For anyone living on the east side of Spokane near the I-90 corridor, a fill-up in Post Falls before coming back across the border is a straightforward $4–5 savings on a full tank.

Where to Find the Cheapest Gas in Spokane

Prices within Spokane vary by neighborhood. The north and northwest corridors, higher-volume commercial areas, tend to be more competitive than downtown or the South Hill.

Search by ZIP code:

• Downtown / near West Central, 99201, urban area, more price variance, check before stopping
• East Central / Logan, 99202, working-class corridor, often competitive on price
• South Hill (upper), 99203, residential premium in spots, compare first
• Northwest Spokane / Hillyard, 99205, solid options along Division Street
• North Spokane / Mead area, 99207, 99208, high-volume commercial strips, reliably competitive

The Costco on the north side and warehouse-club formats near major commercial corridors consistently undercut neighborhood stations by 10–15 cents.

Seasonal Considerations

Spokane winters can briefly push prices up due to winter-blend gasoline switchovers in October and November, but the region generally avoids the prolonged spring blend premium that hits western Washington harder. The broader eastern Washington market tends to be more price-stable across the year than Puget Sound, which swings more dramatically with refinery maintenance cycles.
