Spokane Premium Gas Price: The Truth Behind The Jump
Premium Gas in Spokane: Why It Costs More Now
In Spokane, premium gas is currently about $5.87 per gallon on AAA's Spokane metro average, while the broader Washington average is $5.763 for all grades combined as of May 7, 2026. That means many Spokane drivers are paying well above $5 a gallon for premium today, with station-level prices sometimes a little lower or higher depending on brand and location.
What premium costs now
The most useful number for shoppers is the local average, not a single station price, because Spokane premium varies by neighborhood, retailer, and time of day. AAA's Spokane metro page shows a current premium average of $5.873, compared with $5.846 one day earlier, $5.766 one week earlier, and $5.407 one month earlier.
That trend matters because the phrase premium gas can hide a wide spread between warehouse clubs and convenience stores, especially in a market like Spokane where station pricing changes quickly. For example, recent station listings show Costco locations in Spokane posting premium around $3.59 to $3.61 on older station-specific pages, while current market-wide averages are much higher.

Why prices are rising
The biggest short-term driver is that Washington's fuel market has been moving higher statewide, and Spokane is not immune. AAA shows Washington's average at $5.763, while Spokane's metro premium is even higher at $5.873, indicating local retail conditions can exceed the state average even without a major supply disruption.
Another reason is the broader western fuel structure. Spokane sits east of the Cascades and does not face the same Puget Sound blend requirements that add cost on the west side of the state, but Spokane still depends on regional distribution, refinery economics, and market competition. That means the city can be cheaper than Seattle in many periods and still look expensive compared with national norms.
"Washington's state gas tax is 49.4 cents per gallon, one of the highest in the country," according to a recent Spokane gas-price explainer, which helps explain why prices are elevated even before retail markups are added.
How Spokane compares
Spokane's premium prices are high in absolute terms, but they are still often below the most expensive coastal markets in Washington. In April 2026, local reporting put Spokane's average gas price around $4.065 before the May surge, showing how quickly the market has moved in just a few weeks.
By early May, the city had reached a record-level average for regular gas at $5.31 in Spokane County, and Washington overall was near $5.67 per gallon, the second highest in the country behind California. Even though that report focused on regular fuel, it signals the same market pressure affecting premium grades.
Station-level range
Not all Spokane stations charge the same amount, and the gap between bargain stations and convenience-store pumps can be large. Recent Spokane listings show premium around $3.58 at Maverik, $3.74 at Nomnom, $3.89 at another Nomnom location, and roughly $4.05 at a Conoco station, though availability and posting times can change quickly.
- Warehouse clubs and discount chains usually post the lowest pump prices.
- Interstate-adjacent and convenience locations tend to charge more.
- Prices can change daily, and sometimes multiple times per day.
- Premium fuel typically carries the largest dollar spread when the market is volatile.
What drivers should know
Drivers who need premium should pay attention to octane requirements in the owner's manual, because buying a higher grade than needed is usually wasted money. For vehicles that do require premium, Spokane's current market means a 15-gallon fill-up can easily run close to $90 at many stations, and more at higher-priced retail locations.
- Check the current metro average before you leave home.
- Compare warehouse clubs, supermarkets, and branded stations.
- Use station apps or local fuel guides for same-day pricing.
- Keep an eye on weekly trends, not just one day's number.
Historical context
The recent spike is especially striking because Spokane premium was far lower a year ago. AAA's Spokane metro data shows premium at $4.372 one year ago, which means today's current average is roughly $1.50 higher per gallon. That kind of jump can meaningfully change monthly driving costs for commuters, rideshare drivers, and small businesses.
Spokane also tends to track regional supply shifts more closely than it does national headlines, which is why local news coverage often emphasizes eastern Washington budget stress when fuel markets tighten. In practical terms, the city's premium market is shaped by distribution costs, state taxes, and retailer strategy rather than just crude oil alone.
Frequently asked questions
Bottom line for buyers
If you need premium in Spokane today, expect to pay about $5.87 a gallon on average, with a reasonable real-world range that can dip below $4 at some discount stations and climb above the city average at premium-branded locations. The market has moved sharply higher over the past month, so checking same-day pricing before filling up is the best way to avoid overpaying.
