What Time Does Costco Gas Open and Close?

There is no single national opening or closing time for Costco gas stations. Costco's own customer-service guidance says hours can vary by warehouse and tells shoppers to use the location's Store Details page for gas station hours, holiday adjustments, and closures.

If you need the real answer for today, use Costco's warehouse locator rather than relying on a generic schedule. Costco explicitly says service hours can vary by location.

The direct answer

Costco does not publish one chainwide gas-station schedule that fits every warehouse. In its official hours of operation page, Costco says there may be slight variations in hours for each warehouse and tells you to open a specific location's Store Details to see service hours such as gas station hours. Costco's main gasoline page also links directly to local fuel station locations, hours, and fuel prices.

How to find your exact local gas hours

Open Costco's Find a Warehouse page.
Search by ZIP code, city, or state.
Select your warehouse and open Store Details.
Check the gas station service hours listed for that location.

Costco repeats this process in its hours guidance, and says the same location details will also show adjusted holiday hours and closures.

Why the hours vary

Costco's official hours page says warehouse hours can vary by location, and that same page tells you service departments such as gas stations have their own listed hours. That is the cleanest current source-backed answer for why generic articles often go stale.

So if you see a blog claiming every Costco gas station opens at the same time, treat that as a convenience estimate, not Costco policy.

Holiday closures and adjusted hours

Costco's holiday closures page says U.S. warehouses are closed on New Year's Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. Costco also says on its hours page that local Store Details will show adjusted holiday hours and closures.

Because Costco ties service-hour changes to the local listing, check the exact station before a holiday trip.

Who can buy Costco gas

Costco's current fuel FAQ says the fuel station is open to Costco members only, with one clear exception: prepaid Costco Shop Card customers do not need to be members.

That matters because knowing the hours is not enough if you arrive without an eligible way to start the transaction.

How you pay at the pump

Payment method	Official Costco guidance
Visa credit cards	Accepted at U.S. Costco gas stations per Costco's payment methods page.
Costco Anywhere Visa by Citi	Accepted at U.S. Costco gas stations per the same official page.
Most PIN debit cards	Accepted according to Costco.
Apple Pay	Listed by Costco as accepted at U.S. gas stations on its payment page.
Costco Shop Cards	Accepted according to both Costco's payment methods page and fuel FAQ.

Costco's fuel FAQ also notes that Oregon and New Jersey are full-service per law.

Why you may see a temporary hold

Costco's gas station FAQ says that when fuel is bought with a PIN debit card or Visa card, Costco requests a pre-authorization from the card issuer before fueling starts. Costco says that approved amount may be up to $150, and that it sends the completion transaction with the actual purchase amount immediately after fueling.

If you are comparing payment methods, this explains why a gas purchase can briefly look larger than the final charge on your statement.

Why Costco gas is popular

Costco's main gasoline page says members get access to Kirkland Signature fuel, and Costco's Kirkland Signature gasoline page says the fuel is tested for quality and formulated with deposit-control additives. Costco's current fuel FAQ also says its fuels are certified to meet TOP TIER performance standards.

Those quality claims are official. Price competitiveness, however, still varies by local market, so it is better framed as a location-by-location comparison than a universal guarantee.

Practical tips that are still safe to say

Use the local station listing before you drive over, especially on weekends and holidays.
Bring an accepted payment method and your membership card unless you are using a prepaid Costco Shop Card.
If you use Visa or PIN debit, expect a temporary pre-authorization hold per Costco's gas station FAQ.
Do not assume warehouse hours and gas hours are identical; Costco treats gas as a service category with its own listing in Store Details.

Bottom line: local store details beat generic schedules

Costco gas hours open and close at different times depending on the location, and Costco's own guidance tells you to verify the service hours on the local warehouse page. If you remember one thing, remember this: check the station's Store Details before you leave, especially around holidays, and bring a valid membership or prepaid Costco Shop Card plus an accepted payment method.
