Planning your fuel stop just got smarter. If you’re wondering about Costco gas hours, you’re not alone—millions rely on these affordable pumps weekly. But knowing when to go can save you time, money, and frustration. Let’s dive into everything you need to know.
Costco Gas Hours: What Time Do They Open and Close?
One of the most frequently asked questions by both new and seasoned Costco members is: what are the standard Costco gas hours? While there’s no single answer that applies to all locations, most Costco gas stations operate between 6:00 AM and 8:00 PM daily. However, these hours can vary significantly based on location, local regulations, and even seasonal demand.
Typical Daily Operating Hours
On average, Costco gas stations open around 6:00 AM and close by 8:00 PM. This window allows early risers and late commuters to refuel conveniently. These hours are designed to align with the warehouse store’s operating times, although the gas station often opens a bit earlier and closes a bit later than the main building.
- Most locations open between 6:00 AM – 7:00 AM
- Evening closure typically between 7:00 PM – 9:00 PM
- Peak hours are usually 7–9 AM and 4–6 PM
It’s important to note that Costco does not operate its gas stations 24/7. Unlike some standalone gas stations, Costco prioritizes member experience and safety, which means limited nighttime operations in most areas.
Regional Variations in Costco Gas Hours
Costco operates over 600 warehouses in the U.S. alone, and gas station hours can differ from state to state. For example, locations in California may open earlier due to heavy commuter traffic, while stations in less populated areas like Montana might have shorter operating windows.
Urban locations often extend their hours to accommodate rush-hour traffic, while rural stations may close earlier due to lower demand and staffing limitations. Always verify the specific hours for your local Costco using the official Costco warehouse locator.

Why Costco Gas Hours Matter for Your Savings
Costco gas is known for offering some of the lowest fuel prices in the country—often 10 to 30 cents cheaper per gallon than nearby competitors. But to truly maximize your savings, timing is everything. Knowing the exact Costco gas hours at your local warehouse can help you avoid long lines and ensure you get the best possible price without wasting time.
Avoiding Peak Traffic Times
Peak fueling times at Costco gas stations typically coincide with morning and evening commutes. Arriving between 7:00 AM and 9:00 AM or 4:00 PM and 6:30 PM can mean long lines, sometimes with wait times exceeding 20 minutes.
By checking your local Costco gas hours and planning your visit during off-peak times—such as mid-morning (10–11 AM) or mid-afternoon (2–3 PM)—you can drastically reduce your wait time and get back on the road faster.
- Best time to refuel: 10:00 AM – 11:30 AM
- Second-best window: 1:00 PM – 2:30 PM
- Worst times: Weekday mornings and evenings during rush hour
Maximizing Pump Availability
Costco gas stations usually have between 8 and 12 pumps, depending on the size of the warehouse. During peak hours, all pumps can be occupied, forcing drivers to wait in line. By aligning your visit with less busy Costco gas hours, you increase your chances of pulling up directly to an open pump.
Additionally, some locations refill their underground tanks early in the morning. Fueling during or just after this process ensures you’re getting fresh, high-quality gasoline, which can contribute to better engine performance over time.
How to Find Accurate Costco Gas Hours for Your Location
While general trends exist, the only way to know the precise Costco gas hours for your nearest warehouse is to check directly with Costco. Relying on third-party apps or outdated Google listings can lead to wasted trips and frustration.
Using the Official Costco Website
The most reliable method to find current gas station hours is through the Costco warehouse locator. Simply enter your zip code or city, select your nearest warehouse, and view the full details—including gas station operating hours.
This information is updated regularly by Costco’s corporate team and reflects any temporary changes due to holidays, maintenance, or staffing issues.
Calling Your Local Warehouse
If the website doesn’t provide clear gas hours, calling the warehouse directly is the next best step. Most Costco customer service desks can confirm gas station availability and even advise on current wait times.
Pro tip: Call between 10:00 AM and 2:00 PM, when staff are less busy, for the quickest response.
- Ask specifically: “Are the gas pumps currently open?”
- Inquire about any planned closures or maintenance
- Confirm if diesel is available, if needed
Weekend vs. Weekday Costco Gas Hours
Many members assume that Costco gas stations operate on the same schedule every day of the week. While this is true for some locations, others adjust their Costco gas hours based on the day. Understanding these differences can help you plan smarter refueling stops.
Saturday and Sunday Operating Times
Weekend Costco gas hours are often similar to weekday hours, but with slight variations. Some warehouses extend gas station operations on Saturdays to accommodate weekend travelers and road trippers.
For example, a location that closes at 8:00 PM on weekdays might stay open until 9:00 PM on Saturdays. Sundays, however, may see slightly reduced hours, especially in areas with lower weekend traffic.
“I always fill up on Saturday mornings—less traffic, more pumps open.” — Sarah T., Costco Member for 8 Years
Holiday and Special Event Schedules
Costco gas stations may alter their hours during major holidays like Thanksgiving, Christmas, and New Year’s Day. While the warehouse might be closed, the gas station could remain open for limited hours to serve essential travelers.
For instance, on Thanksgiving Day, some warehouses close entirely, but select gas stations operate from 7:00 AM to 3:00 PM. Always verify holiday hours in advance through the Costco app or by calling the location.
- Memorial Day, July 4th, and Labor Day often have normal gas hours
- Christmas Eve and New Year’s Eve may have shortened hours
- Black Friday sometimes sees extended gas operations
Costco Gas Hours and Membership Requirements
Access to Costco gas is one of the most valued member benefits, but it comes with rules. You must be a current Costco member to purchase fuel, and your membership card must be physically presented at the pump.
Who Can Use the Costco Gas Station?
Only Costco members with a valid membership card can buy gas. This includes both Gold Star and Executive members. While guests can ride along, only the cardholder can initiate the transaction at the pump.
Additionally, Costco has strict policies against fuel resale or commercial use. If a member is caught filling large containers or using gas for business vehicles excessively, their fuel privileges may be revoked.
Using Your Costco Credit Card at the Pump
While you don’t need a Costco credit card to buy gas, using the Citi Costco card can earn you cashback rewards. However, you must first activate the card at the gas pump by inserting it and entering your ZIP code.
Important: The card must be activated in-store at least once before it works at the pump. This security measure prevents fraud and ensures only legitimate members use the service.
- Insert card at pump and enter ZIP code
- Wait for approval before removing the card
- Select fuel type and begin pumping
Costco Gas Hours vs. Competitors: A Time-Based Comparison
How do Costco gas hours stack up against other major fuel retailers? While Costco offers lower prices, its operating hours are generally more limited than 24/7 stations like Shell, Exxon, or 7-Eleven.
Comparison with Walmart and Sam’s Club
Walmart gas stations typically operate from 6:00 AM to 10:00 PM, offering longer hours than most Costco locations. Sam’s Club, Costco’s biggest competitor, often keeps its gas stations open from 6:00 AM to 8:00 PM—very similar to Costco.
However, Sam’s Club may offer more flexibility in urban areas, with some locations open until 10:00 PM. Both require membership, but Sam’s Club tends to have fewer restrictions on card usage at the pump.
- Costco: 6 AM – 8 PM (avg)
- Sam’s Club: 6 AM – 8 PM (some until 10 PM)
- Walmart: 6 AM – 10 PM (non-member access)
Price vs. Convenience Trade-Off
The trade-off between price and convenience is real. While a 24-hour gas station offers flexibility, it rarely matches Costco’s per-gallon savings. For budget-conscious drivers, adjusting your schedule to fit Costco gas hours is a small price to pay for significant long-term savings.
For example, saving $0.25 per gallon on a 15-gallon tank equals $3.75 per fill-up. Over a year, that could total over $200 in savings—enough to justify a minor schedule adjustment.
Tips for Getting the Most Out of Costco Gas Hours
Maximizing your experience at the pump goes beyond just knowing when Costco gas is open. With a few smart strategies, you can save time, avoid frustration, and make every visit efficient.
Arrive Early or Late to Beat the Crowd
The golden rule of Costco gas: avoid peak hours. Arriving within the first hour of opening (6–7 AM) or during the last two hours before closing (6–8 PM) can significantly reduce wait times.
Early morning visits are especially effective on weekdays when most people are still at home. Late afternoon visits work well on weekends when the initial rush has subsided.
Use the Costco App for Real-Time Updates
The Costco mobile app is a powerful tool for checking warehouse and gas station hours. It also provides real-time updates on fuel availability, including whether regular, premium, or diesel is in stock.
Some users report that the app shows live wait times during peak seasons, though this feature is not yet available nationwide. Enabling location services ensures you get the most accurate data for your nearest warehouse.
- Check gas prices and hours before leaving home
- Use GPS navigation within the app to find the nearest location
- Receive alerts for price drops or station closures
Common Myths About Costco Gas Hours Debunked
Over the years, numerous myths have circulated about Costco gas hours and fuel quality. Let’s separate fact from fiction and ensure you’re making informed decisions.
Myth: Costco Gas Stations Are Open 24/7
False. No Costco gas station operates 24 hours a day. While some locations have extended hours, all eventually close. This myth likely stems from confusion with other bulk retailers or gas stations located near Costco warehouses.
Costco prioritizes safety, maintenance, and employee well-being, which means limited nighttime operations. Always confirm hours before making a late-night trip.
Myth: Gas Quality Is Lower Because It’s Cheaper
This is a widespread misconception. Costco’s Kirkland Signature gasoline meets Top Tier detergent standards, meaning it contains higher levels of cleaning agents than required by the EPA. Independent tests have shown Costco fuel performs as well as or better than major brands like Chevron and Shell.

In fact, many mechanics recommend Costco gas for its consistent quality and additive content, which can reduce carbon buildup in engines over time.
What are the typical Costco gas hours?
Most Costco gas stations are open from 6:00 AM to 8:00 PM, seven days a week. However, hours vary by location, so it’s best to check the Costco website or call your local warehouse for the most accurate information.
Can non-members buy gas at Costco?
No, only active Costco members can purchase fuel. You must present a valid membership card at the pump. Guests cannot buy gas independently, even if they’re riding with a member.
Does Costco sell diesel fuel?
Yes, many Costco locations offer diesel fuel, but not all. Availability varies by warehouse. It’s recommended to check the Costco website or app to confirm if diesel is available at your preferred location.
Are Costco gas hours different on holidays?
Yes, holiday hours may differ. On major holidays like Thanksgiving or Christmas, gas stations may have shortened hours or be closed entirely. Always verify holiday schedules in advance.
Why is Costco gas so cheap?
Costco keeps gas prices low by operating on a minimal markup model. They sell fuel at near-cost prices to drive warehouse traffic and reward members. Their bulk purchasing power and efficient operations allow them to offer savings without sacrificing quality.
Understanding Costco gas hours is more than just knowing when the pumps are open—it’s about maximizing value, saving time, and avoiding common pitfalls. From weekday vs. weekend variations to membership rules and competitor comparisons, being informed ensures you get the most out of your membership.
