Costco Fuel Pump Hours: Everything You Need to Know in 2026

Costco fuel pump hours are not 24/7, but they have been significantly extended in 2025 to give members more flexibility. As of 2026, most Costco gas stations in the United States operate Monday through Friday from 6:00 AM to 10:00 PM, Saturday from 6:00 AM to 8:30 PM, and Sunday from 6:00 AM to 7:30 PM. These hours represent a major improvement from the previous schedule, and they have been widely praised by Costco members who no longer have to rush to beat early closing times.

Understanding Costco Gas Station Hours in 2026

Costco made a major operational change in February 2025 by extending gas station hours nationwide. This change proved hugely successful, with CEO Ron Vachris reporting two all-time highest gallon sales weeks in April 2025 following the extended hours rollout. The extended hours significantly improved member satisfaction and station throughput. Instead of rushing to beat closing time, members now have a comfortable window from early morning until late evening.

Standard Operating Hours

Weekday Schedule (Monday–Friday): Most Costco gas stations across the United States now operate from 6:00 AM to 10:00 PM. This 16-hour window accommodates early commuters and late workers. The extended closing time means you can fuel up after dinner without rushing.

Weekend Hours:

• Saturday: 6:00 AM to 8:30 PM at most locations
• Sunday: 6:00 AM to 7:30 PM at most locations

Some high-traffic stations may have extended weekend hours, but these are the standard times you can expect at the vast majority of locations.

Important: Hours Vary by Location

While most locations follow standard hours, some regions adjust schedules based on local factors. California and Hawaii warehouses may have slightly different operating times. Always verify your specific station’s hours using Costco’s official website or app before visiting.

Gas station hours don’t always match warehouse hours. Many Costco gas stations stay open after the warehouse closes. You can fuel up without entering the main building as long as you have your membership card.

Holiday Closures

Costco gas stations close completely on major holidays when warehouses shut down. Plan ahead for these closures to avoid showing up to locked pumps:

Full Closure Holidays:

• New Year’s Day (January 1)
• Easter Sunday
• Memorial Day (last Monday in May)
• Independence Day (July 4th)
• Labor Day (first Monday in September)
• Thanksgiving Day
• Christmas Day (December 25)

Today is Saturday, July 4, 2026, which means Costco gas stations are closed today for Independence Day. Plan your fuel stops accordingly.

Other holidays may feature reduced hours rather than complete closures. Check your local station’s holiday schedule a few days in advance to avoid wasted trips during holiday periods. Some locations post holiday hours at the pump area. The Costco app and website also update holiday schedules.

Can You Get Costco Gas When the Store Is Closed?

Yes, absolutely. This is one of the most common questions Costco members ask, and the answer is straightforward. Costco gas stations operate independently from the warehouse in terms of hours. Most gas stations open earlier and close later than the main store.

For example, at the El Centro, California warehouse, the gas station operates Monday–Friday from 6:00 AM to 10:00 PM, while the warehouse opens at 10:00 AM for Gold Star members and closes at 8:30 PM. That means you have several hours of extra access to the gas pumps both before and after the store is open.

What You Need for After-Hours Fueling

Your active Costco membership card is required to access the pumps at any time, whether the warehouse is open or closed. You will scan it at the pump before fueling. If your membership has expired, you will not be able to access the gas pumps.

Payment methods at after-hours pumps: Costco only accepts Visa credit cards, debit cards, or digital payment methods. Cash is not accepted for any Costco gas purchase, regardless of the time of day.

Recent Changes: The 2025 Hour Expansion

In February 2025, Costco announced through its social media channels that gas station hours would be expanded. Previously, pumps closed at 8:30 PM on weekdays. The new schedule added 1.5 hours on weekdays (now closing at 10:00 PM), 1.5 hours on Saturdays (now closing at 8:30 PM), and additional time on Sundays.

Costco CEO Ron Vachris told investors during the company’s first-quarter earnings call: "We also extended our gas station hours during the quarter to make filling up at Costco more convenient for our members. Generally, our stations are now staying open an hour later than they did previously, with some opening earlier as well."

The financial results speak for themselves. During Costco’s third-quarter earnings call, Vachris confirmed that the company experienced two of its "all-time highest gallon weeks" in the U.S. in April 2025, which he attributed to "expanded gas station hours, new gas station openings and lower prices at the pump."

Best Times to Visit Costco Gas Stations

Strategic timing helps you avoid long lines at Costco gas stations. Understanding peak and off-peak patterns makes fueling up faster and less stressful.

Least Busy Times

• Early mornings (6:00 AM – 8:00 AM): Opening hours offer the shortest wait times. One satisfied customer posted on X: "Found out that the gas station at COSTCO opens at 6AM. It's on my way to work. No lines and top tier gas for 2.48."
• Late evenings (8:00 PM – 10:00 PM): Most shoppers have already fueled up
• Tuesday–Thursday midday: Midweek lulls mean fewer cars
• Sunday evenings: After 6:00 PM crowds thin out significantly

Times to Avoid

• Saturday 9:00 AM – 12:00 PM: Weekend shoppers create peak traffic
• Weekday afternoons (3:00 PM – 6:00 PM): Post-work rush hits hard
• Right after warehouse opening: Members combine shopping with fueling
• Day before holidays: Everyone tops off before travel

The extended hours implemented in 2025 help distribute traffic more evenly throughout the day. Members no longer rush to fuel up before early closing times.

Recent Station Expansions and Improvements

Costco continues investing in gas station infrastructure throughout 2025 and 2026. Several locations are expanding capacity to reduce wait times during peak periods.

Notable Expansions

• Coon Rapids, Minnesota: Received city council approval to double its fuel capacity from 10 to 20 pumps. The expansion addresses chronic traffic congestion where vehicle lines frequently spilled onto main roads during peak times.
• Rochester, New York: Added eight pumps (four double-sided positions) during a recent expansion project.

Standalone Gas Station Coming in 2026

The most groundbreaking development is Costco building its first-ever standalone gas station in Mission Viejo, California. This 40-pump facility will operate from 5:00 AM to 10:00 PM daily starting spring 2026, offering membership-only access without an attached warehouse. This represents a major shift in Costco’s fuel strategy and could lead to more standalone locations nationwide.

How Costco Gas Hours Compare to Competitors

Costco’s after-hours access is a real advantage. Here is how it stacks up against competitors:

Costco’s combination of extended hours AND low prices makes it a strong value play for members planning their fuel purchases strategically.

Why Costco Gas Is Worth the Trip

Top Tier Quality Fuel

Costco sells Kirkland Signature gasoline that meets TOP TIER performance standards. This high-quality fuel contains enhanced detergent additives that help clean your engine and restore fuel economy over time. All Costco fuel meets the same strict standards as major brands like Shell and Chevron. You get premium quality without premium prices.

Significant Savings on Every Fill-Up

Costco gas maintains an average 53 cents per gallon discount compared to market rates. In some regions, savings reach 65 cents per gallon. These savings make the membership worth it for gas alone for many drivers. Gas sales represent approximately 12% of Costco’s total revenue. This huge volume lets them negotiate better wholesale prices, and they pass those savings directly to members.

Executive members earn 2% cash back on gas purchases, adding 16–20 cents per gallon in savings on $4/gallon gas.

Membership and Payment Requirements

• Membership required: Both Gold Star ($65/year) and Executive ($130/year) members can purchase fuel
• Accepted payment: Visa credit cards, debit cards, and digital payment methods
• Not accepted: Cash, Mastercard, American Express, Discover

When Your Car's Fuel Pump Needs Attention

While Costco provides excellent access to affordable fuel, your vehicle's own fuel pump is a different matter. Understanding the signs of a failing fuel pump can save you from being stranded and help you plan for replacement costs.

Signs Your Fuel Pump Needs Replacement

Whining Noise: One of the first things you might notice with a bad fuel pump is that your car sounds different when it is on. A well-functioning fuel pump generally gives off a soft humming noise when your vehicle starts up. If instead you hear a sharp whining sound from your fuel tank, this is very likely a sign you need a new fuel pump.

Hard Starts: A failing fuel pump can cause your car to have difficulty starting. One of the fuel pump's primary jobs is to keep a level of static pressure within the fuel system so the pump does not need to completely re-prime the entire system again on startup. As your fuel pump ages, it can lose the ability to keep this static pressure, causing you to have to crank your car for a considerable amount of time before starting.

Lack of Power: A weak fuel pump will often not hold sufficient pressure for the fuel injection system to operate properly. In many cases, the vehicle can start, but acceleration can be a problem with hesitation, lack of power, or stalling.

Fuel Gauge Issues: In modern vehicle fuel pumps, the pump assembly usually contains the fuel-level sending unit as well. If your fuel gauge is not properly working, you can often trace it to a fuel pump assembly unit not functioning properly.

Car Won't Start: Finally, you may not be able to get your car to start at all. Unfortunately, many pumps do not give any warning sign of their failure. Sometimes a pump can die while the vehicle is on the road, and other times the vehicle shuts off, the pump seizes, and never starts again.

Fuel Pump Replacement Costs

The cost to replace a fuel pump varies significantly depending on your vehicle. The average fuel pump part costs around $350, but it could be as low as $15 or more than $2,000 in extreme cases. If you bring your car to a mechanic, you need to account for labor costs as well. The total job can take anywhere from 1 hour for an easy-access pump to over 5 hours if the fuel tank needs to be removed.

Why Quality Matters in Fuel Pump Replacement

When it comes time to replace your fuel pump, choosing the right part is critical. Cheap aftermarket pumps often use lower-grade motors and seals. They may work for a few months but fail prematurely. This means you will have to pay for labor all over again, which is far more expensive than buying a quality part the first time.

The most common cause of fuel pump failure is running the tank too low, which overheats the pump. Other causes include contaminated fuel (dirt, water, or ethanol buildup), old age, and poor-quality aftermarket pumps. Electrical issues like a bad relay or wiring can also mimic pump failure.
