Insider Tip: Costco Gas Price In Spokane And Why It Changes
Costco gas price in Spokane
The current Costco gas price in Spokane, Washington is about 5.19 per gallon for regular fuel at the 5601 E Sprague Ave location, with the north Spokane Costco at 12020 N Newport Hwy listed around 5.23 for regular fuel as of May 8, 2026. Those prices can move quickly during the day, but Spokane Costco gas is still generally below or near the local city average rather than far above it.
For shoppers trying to decide whether to wait in line, the most useful takeaway is that Costco fuel in Spokane is usually priced as a value station, not the absolute cheapest in town every hour, but often one of the lowest brand-name options available. The two Spokane-area Costco stations also differ slightly, so the best price can depend on which warehouse you visit.
Current station prices
Spokane has at least two Costco fuel locations that commonly show up in public fuel trackers: the Sprague Avenue station and the North Newport station. Public listings show the Sprague station at about 5.19 regular and the North Newport station at about 5.23 regular, with premium fuel priced higher at both sites.
| Location | Regular | Premium | Diesel | Notes |
|---|---|---|---|---|
| 5601 E Sprague Ave, Spokane | 5.19 | 5.67 to 5.76 | Not listed | Often cited as the main Spokane Costco fuel site. |
| 12020 N Newport Hwy, Spokane | 5.23 to 5.24 | 5.75 to 5.76 | 6.47 to 6.48 | North Spokane location, slightly higher regular price in recent listings. |
Why the price changes
The gas price at Costco changes because it tracks the wholesale market, local competition, station supply timing, and Costco's own pricing strategy. In practical terms, when rack prices move in the region, Costco usually updates in response, but not always at the exact same minute as nearby stations.
In Spokane, a few local factors matter more than they do in larger coastal markets: regional supply logistics, seasonal driving demand, and Washington's generally higher fuel tax environment. One public tracker also shows that Spokane Costco prices can sit in the low-to-mid 5-dollar range while other Washington Costco stations vary from roughly the low 5s to the mid 5s, which suggests local competition and transport costs are influencing the final pump number.
"Costco really doesn't matter! Neither does Safeway! All gas in WA is above 5 bucks!" one Spokane-area commenter wrote on May 2, 2026, reflecting how elevated Washington fuel prices have felt to many drivers.
Spokane vs. other Washington Costco stations
Spokane's Costco fuel pricing is competitive within eastern Washington, but it can still trail cheaper inland markets by a noticeable margin. For example, public Washington-wide listings show Union Gap at about 5.09 regular and Clarkston at about 4.59 regular, while Spokane sits closer to 5.19 to 5.23.
That spread matters because it shows Spokane is not setting the statewide low, even though Costco remains a reliable discount relative to many retail stations. The size of the gap can help explain why some drivers in eastern Washington plan fuel stops around shopping trips rather than assuming all Costco locations are priced alike.
How to read the numbers
Fuel trackers are useful, but they are not always real-time down to the minute. A station may show a price that was updated earlier in the day, and that is especially important when a price is changing quickly after a wholesale move.
- Check the location first, because Spokane has more than one Costco fuel site.
- Compare regular and premium, since the gap can be large enough to matter for high-mileage drivers.
- Look at the update time, because morning prices can differ from afternoon prices on volatile days.
- Use Costco membership rules and station hours to avoid a wasted trip.
Hours and access
The Sprague Avenue station listing shows fuel hours from 6:00 a.m. to 9:30 p.m. Monday through Friday, and 7:00 a.m. to 7:00 p.m. on Saturday and Sunday. That schedule can matter as much as the posted pump price when drivers are deciding when to fill up.
Costco fuel lanes often move efficiently, but the lower price can attract longer lines during peak commute and weekend shopping hours. For most Spokane drivers, the best strategy is to pair a Costco fuel stop with a warehouse trip or to arrive early before the highest-traffic window.
What influences savings
Costco's fuel discount tends to be most valuable for households that buy gas frequently, drive larger vehicles, or consistently fill up instead of buying a few gallons at a time. Even a 10 to 20 cent difference per gallon can become meaningful across a full tank, especially for SUVs and trucks.
Spokane drivers also benefit from comparing the two local Costco stations against nearby competitors, because a difference of only a few cents can sometimes shift the best buy from one warehouse to the other. Public listings suggest that the North Spokane station can be slightly higher than the Sprague station for regular fuel, though that gap is small enough that convenience may outweigh savings.
Practical local context
In the broader Spokane market, Costco remains one of the most watched fuel brands because it combines membership pricing with relatively fast pump turnover and a reputation for below-average prices. Public station listings show the Costco prices hovering near Spokane's average gasoline price, which implies that Costco is often competitive rather than dramatically undercutting the market.
That competitive positioning is exactly why the Spokane average matters: when the citywide price rises, Costco may still look affordable, but the margin can narrow. When the citywide price falls, Costco may still be the easier benchmark for comparing whether another station is truly cheaper.
What to expect next
Based on the current pricing pattern, Spokane Costco regular gasoline will likely keep moving in small increments rather than large jumps unless wholesale markets or regional supply conditions change sharply. The best near-term expectation is continued fluctuation around the low-to-mid 5-dollar range, with the Sprague and North Newport locations remaining close but not identical.
If you are tracking the best deal, the most useful habit is to check the station you actually plan to use, not just "Costco in Spokane" generically. The price gap between the two locations may be small, but in fuel shopping, location-specific details are the difference between a good fill-up and an average one.
