Costco Gas Hours 2026: Opening, Closing & Weekend Times

Costco gas hours are important to know before heading out to fill your tank, especially if you plan to visit early in the morning, late at night, or on a weekend. Costco gas stations often operate on a different schedule from the warehouses, meaning the fuel pumps may open earlier and close later than the store itself.

In 2026, many Costco gas stations open at 6:00 AM on weekdays and close at 10:00 PM. However, some locations open as early as 5:30 AM, while weekend schedules are generally shorter.

This guide covers verified Costco gas station hours, weekday and weekend schedules, holiday closures, fuel availability, and how to find accurate opening and closing times near you.

Quick Answer

Many Costco gas stations operate from 6:00 AM to 10:00 PM Monday through Friday, 6:00 AM to 8:30 PM Saturday, and 6:00 AM to 7:30 PM Sunday. These times are confirmed for several Costco locations, but they are not a universal nationwide schedule. For example, the Poway, California, gas station opens at 5:30 AM on weekdays. Always check the gas station hours listed for your specific Costco warehouse before visiting.

Costco Gas Hours at a Glance

These hours are examples from current official Costco location listings, not guaranteed hours for every station.

What Time Does Costco Gas Open and Close?

Costco gas stations have their own operating hours, which may extend beyond normal warehouse shopping hours.

At several locations reviewed in October 2026, fuel stations open at 6:00 AM on weekdays and remain open until 10:00 PM. However, opening times can differ depending on the station.

What Time Does Costco Gas Open?

Many Costco gas stations open at 6:00 AM Monday through Saturday.

Some locations open earlier. For example, Costco’s official page for the Poway warehouse in California lists weekday gas station opening at 5:30 AM.

This means you may be able to purchase gasoline before the warehouse opens for shopping.

What Time Does Costco Gas Close?

At several verified locations, Costco gas stations close at:

• Monday–Friday: 10:00 PM
• Saturday: 8:30 PM
• Sunday: 7:30 PM

These closing times apply to the specific locations reviewed. Other locations may publish different schedules or temporary operating changes.

For reliable information, use the Gas Hours section on your selected warehouse’s official location page rather than relying on the warehouse’s general closing time.

Costco Gas Hours by Day

The following table shows the published fuel station schedules for Costco’s Manassas, Virginia, and Chula Vista, California, locations, which shared the same hours when checked on October 30, 2026.

This is a verified example schedule, not a nationwide guarantee.

The Poway, California, station follows the same listed closing times but opens at 5:30 AM on weekdays.

Do Costco Gas Hours Vary by Location?

Yes. Costco publishes gas station hours for individual warehouses rather than providing a single schedule that applies to every U.S. location.

A comparison of three official Costco location pages shows a difference in weekday opening hours.

These examples show that even stations with identical weekend schedules can have different weekday opening times.

They should not be interpreted as representative of every Costco gas station in Virginia, California, or the United States.

Costco Gas Hours on Saturday and Sunday

Costco gas stations at the reviewed locations remain open on both Saturday and Sunday, although their schedules are shorter than weekday hours.

What Time Does Costco Gas Open on Saturday?

The Manassas, Poway, and Chula Vista locations list Saturday gas station hours of 6:00 AM to 8:30 PM.

This provides an example of a weekend schedule that starts early but ends before the weekday closing time.

What Time Does Costco Gas Close on Sunday?

The same three locations list Sunday fuel station hours of 6:00 AM to 7:30 PM.

Sunday hours are especially important to verify because the gas station may close at a different time from the warehouse.

For instance, the reviewed Costco warehouses list general Sunday shopping hours ending at 6:00 PM, while their gas stations remain scheduled to operate until 7:30 PM.

Is Costco Gas Open 24 Hours?

The Costco gas stations reviewed do not operate 24 hours a day.

Their published schedules include specific opening and closing times, even though the fuel stations may remain available beyond warehouse shopping hours.

If you need gasoline late at night, check the exact station schedule before traveling. A warehouse being closed does not automatically mean its gas station is closed, but neither does it guarantee that the pumps will remain accessible overnight.

Costco Gas Holiday Hours 2026

Costco gas station hours may change on major U.S. holidays. Some stations close entirely, while others may follow special schedules.

Costco’s official location finder displays upcoming holiday closures, making it an important resource before a holiday trip.

Is Costco Gas Open on Thanksgiving?

Costco’s official location information identifies Thanksgiving Day, November 26, 2026, as a closure for multiple U.S. warehouses, including Chula Vista, California.

However, a warehouse holiday closure listing should not automatically be treated as separate confirmation of the associated fuel station’s operating status. Confirm the gas station’s holiday availability before visiting.

Is Costco Gas Open on Christmas Day?

Christmas Day is December 25, 2026.

A nationwide Costco gas station schedule for Christmas Day has not been independently confirmed in this guide. Check your selected Costco location’s holiday information before making a trip.

Is Costco Gas Open on Christmas Eve?

Christmas Eve falls on December 24, 2026.

Holiday operating hours may differ from the regular weekday schedule. Consult the official Costco location page for any special closing time.

Is Costco Gas Open on New Year’s Day?

New Year’s Day falls on January 1, 2027.

Do not assume regular Friday fuel station hours will apply. The station’s holiday status should be confirmed using Costco’s current location information.

Other Major Holidays

For Memorial Day, Independence Day, Labor Day, Easter, and New Year’s Eve, check the individual Costco fuel station’s published schedule.

A regular opening time shown for a weekday or weekend does not guarantee availability on a public holiday.

Are Costco Gas Station Hours the Same as Warehouse Hours?

No. Costco lists warehouse shopping hours and gas station hours separately.

For example, the official Manassas, Virginia, location page shows the following schedules:

The difference is important for members who want to refuel outside normal warehouse shopping hours.

You may be able to purchase gas before the warehouse opens or after it closes, provided the fuel station is operating according to its published schedule.

Warehouse membership shopping hours should not be used as a substitute for the fuel station’s hours.

How to Check Costco Gas Hours Near You

The most reliable way to find Costco gas hours near you is to use Costco’s official warehouse or fuel station locator.

Follow these steps:

1. Open Costco’s official website.
2. Select the Find a Warehouse option.
3. Enter your city, state, or ZIP code.
4. Apply the Gas Station filter to find warehouses offering fuel.
5. Select your preferred Costco location.
6. Find the Gas Station section and review its Gas Hours.
7. Check any upcoming holiday closures or special notices.

Costco’s fuel station locator also provides location-specific gasoline pricing information.

Can Google Maps Show Costco Gas Hours?

Google Maps can be useful for locating nearby Costco fuel stations and viewing their listed operating schedules.

However, the official Costco location page is the better primary reference because it distinguishes gas station hours from warehouse hours.

If the information conflicts, contact the specific Costco warehouse for confirmation.

What If Your Costco Gas Station Has Different Hours?

If your local station displays hours that differ from examples published elsewhere, follow its current official location information.

A phone call to the warehouse can also help clarify temporary closures, special holiday schedules, or a discrepancy between published information and the station’s actual operation.

Do You Need a Costco Membership to Buy Gas?

Costco’s official fuel station FAQ states that its gas stations are generally reserved for Costco members.

However, there is an important exception: customers paying with a prepaid Costco Shop Card do not need to be Costco members.

Members can use their membership cards at the fuel station, while eligible nonmembers can use a Costco Shop Card under Costco’s published conditions.

This distinction matters if you are visiting a Costco fuel station without an active membership.

What Payment Methods Does Costco Gas Accept?

Costco fuel stations in the United States accept several payment methods.

According to Costco’s official 2026 payment information, accepted methods include:

• Visa credit cards
• Costco Anywhere Visa Card by Citi
• Most PIN-based debit or ATM cards
• Apple Pay
• Costco Shop Cards
• Certain additional eligible payment cards identified by Costco

Costco’s fuel station FAQ explains that its stations generally use pay-at-the-pump technology, with full-service exceptions in New Jersey and Oregon under applicable state requirements.

Cash and personal checks are not listed as direct payment methods at the fuel pumps. Costco Shop Cards provide an alternative for eligible customers.

What Types of Gas Does Costco Sell?

Costco sells Kirkland Signature gasoline, with regular and premium fuel prices displayed on individual warehouse location pages.

The company also identifies specific locations that offer Kirkland Signature diesel fuel.

Regular and Premium Gasoline

The reviewed Costco warehouse pages list separate prices for regular and premium gasoline.

However, exact prices change and should not be assumed to remain the same throughout the day.

Costco states that fuel purchases are charged at the price posted on the pump at the time of purchase.

Does Every Costco Gas Station Sell Diesel?

No nationwide diesel availability should be assumed.

Costco maintains a dedicated list of stations that offer Kirkland Signature diesel. Check the official fuel locator to determine whether your preferred location sells diesel before traveling there.

Can You Check Costco Gas Prices Before Visiting?

Yes. Costco displays fuel prices for individual stations through its official location information.

To find the available prices, select a warehouse with a gas station and review its fuel section.

The displayed prices can help you compare local options, but they are not guaranteed to match the pump price when you arrive.

Costco specifically explains that its online prices are updated frequently but may differ from the amount posted at the fuel pumps.
