Costco is known for offering some of the most competitive fuel prices in Alaska, consistently undercutting nearby gas stations by 10 to 30 cents per gallon. In cities like Anchorage and Fairbanks, where fuel costs tend to run higher than the national average, the savings at the Costco pump can add up quickly for members who fill up regularly.
Because gas prices fluctuate daily based on market conditions, refinery capacity, and regional supply logistics, we don't publish specific per-gallon prices on this page. Instead, use our interactive map to find the nearest Costco fuel station and check current pricing at the pump. Alaska's unique geography and limited refinery infrastructure can lead to wider price swings than in the lower 48, making Costco's member-only pricing especially valuable.
Alaska currently has 1 Costco location with diesel fuel — the Costco warehouse in Anchorage on Dimond Boulevard. This single diesel station serves a large geographic area, so if you're driving a diesel truck or RV through south-central Alaska, it's worth planning your fuel stops accordingly. The Anchorage location offers high-quality ultra-low sulfur diesel (ULSD) that meets all manufacturer specifications.
For diesel drivers in Fairbanks, Juneau, or other parts of the state where Costco doesn't yet offer diesel, consider topping up at commercial truck stops or Chevron and Tesoro stations along major highways. Costco has been gradually expanding its diesel availability across the U.S., and additional Alaska locations may add diesel pumps in the future. Using quality diesel fuel additives can help maintain engine performance in Alaska's harsh climate.
Costco gas stations in Alaska typically operate from 6:00 AM to 10:00 PM on weekdays, with slightly reduced hours on weekends. Hours may be shorter during winter months due to daylight and weather conditions. A valid Costco membership is required to purchase fuel — both Gold Star and Executive memberships work at the pump. Executive members earn 2% cash back on qualifying gas purchases (subject to an annual cap), which can add up to meaningful savings for frequent drivers.
