It is 11:15 PM. You are coasting on fumes, the low-fuel light is glaring at you like an accusatory eye, and you see those familiar red and blue signposts in the distance. You think to yourself, can you get gas at costco after hours just because the pumps are sitting there, brightly lit and unattended?
The short answer is a flat no.
Costco isn't like your local 7-Eleven or a 24-hour Shell station. They don't leave the credit card readers active once the staff goes home. It is one of those quirks of the membership model that catches people off guard, especially if you are used to the "always open" nature of modern American infrastructure. Most people assume that because a station is "pay-at-the-pump," it doesn't need a human being on-site to function. At Costco, that is simply not how the gears turn.
Why the Pumps Go Dark When the Warehouse Closes
Costco operates on a razor-thin margin. Honestly, they make their money on memberships, not the rotisserie chickens or the Kirkland Signature gasoline. To keep those fuel prices five to thirty cents lower than the gas station across the street, they cut overhead. That means they don't pay for 24/7 security or overnight attendants.
Every Costco fuel station is required to have a certified attendant on-site during operational hours. This isn't just a corporate policy; in many jurisdictions, it is a fire code and safety requirement for high-volume stations. These attendants do more than just help seniors with the card reader. They manage the emergency shut-off valves, clean up spills with that grainy absorbent stuff, and make sure nobody is smoking near the vapor recovery systems.
Once that attendant clocks out, the system locks down.
Typically, the gas station hours are a bit more generous than the warehouse hours. You might find the pumps opening at 6:00 AM and closing at 9:30 PM on a weekday, while the main store doesn't open until 10:00 AM. But once those lights dim, the pumps are bricked. You can swipe your Visa or your membership card all you want, but the software will just stare back at you with a "Station Closed" message.

The Membership Gatekeeper
There is also the matter of the "Costco Shop Card" and membership verification. Because the system has to ping a database to ensure your membership is active before it even authorizes a payment, the backend systems are often tied to the operational window of the specific location.
If you're wondering about can you get gas at costco after hours using a gift card you found in your glovebox, the answer remains the same. The physical hardware is disabled. It’s not just about the payment; it’s about the liability of dispensing thousands of gallons of flammable liquid without a set of human eyes on the premises.
A Breakdown of Typical Operating Windows
While every location varies slightly based on local demand and municipal laws, most follow a predictable rhythm.
On Mondays through Fridays, you’re looking at a 6:00 AM start and a 9:30 PM finish. Saturday usually sees a slight contraction, maybe closing at 7:00 PM or 8:00 PM. Sunday is the real kicker—many stations wrap up by 6:00 PM or 7:00 PM. If you are rolling into the parking lot at 8:00 PM on a Sunday night, you are almost certainly out of luck.
The "Holiday" Trap
Costco is one of the few remaining giants that actually shuts down for major holidays. We aren't just talking about Christmas. They close for:
- New Year’s Day
- Easter Sunday
- Memorial Day
- Independence Day
- Labor Day
- Thanksgiving
- Christmas Day
On these days, the gas stations are closed too. Entirely. Do not expect the pumps to be active just because there aren't cars in the lot. If the warehouse is closed for a holiday, the fuel is staying in the underground tanks. I’ve seen people pull up to the cones on Thanksgiving morning, looking genuinely baffled that the "pay-at-the-pump" system isn't working. It’s a ghost town for a reason.

Is There Any Workaround?
People always look for a loophole. "What if I stay in the line right as they are closing?"
Costco attendants are notoriously efficient. When the clock hits the closing minute, they usually start placing orange cones at the entrance of the fuel lanes. If you are already at a pump and have started your transaction, the system will generally let you finish. However, if you pull up one minute after the closing time and the attendant is pulling the gate or setting the cones, they won't let you in. They have schedules to keep and strict labor hour targets.
Interestingly, some newer "business center" Costco locations have different hours, but even they follow the "no attendant, no gas" rule.
The Quality Factor: Why People Wait Anyway
Why do we care so much about these hours? Why not just go to the 24-hour Mobil down the street?
It’s the "TOP TIER" certification. This isn't just marketing fluff. Groups like AAA have conducted independent studies showing that TOP TIER gasoline—which contains higher levels of detergents—actually keeps engines cleaner and improves fuel economy over the long haul. Costco is one of the cheapest places to get this high-detergent fuel.
Basically, your car's intake valves stay cleaner.

But that quality comes with the trade-off of limited availability. You trade convenience for price and performance. If you need fuel at 2:00 AM, you're paying the "convenience tax" at a standard station.
What to Do if You Are Stranded
If you find yourself at a closed Costco with the needle on empty, your best bet is to use an app like GasBuddy or even Google Maps to filter for "Open Now." In most suburban areas, there is a 24-hour station within a three-mile radius of a Costco. You’ll pay more per gallon—sometimes significantly more—but it’s better than a towing bill.
If you have a Costco Anywhere Visa® Card by Citi, remember that you still get your 4% cashback on gas at other stations too (up to the first $7,000 per year, then 1%). So, if you're forced to buy gas after hours at a Chevron or a Circle K, you are at least softening the blow by using that specific card.
Real-World Nuance: The "Soft" Opening
One thing many regulars know is that Costco often opens its gas lanes 15 to 30 minutes before the posted opening time. If the sign says 6:00 AM, the attendant is often there by 5:30 AM getting things ready. If they finish their safety checks early, they'll open the lanes. This is the "golden hour" for contractors and early commuters who want to avoid the 10:00 AM rush when the warehouse opens and the parking lot becomes a battlefield.
But the evening is different. Closing time is a hard wall.
Final Insights for the Costco Fuel Run
The reality is that can you get gas at costco after hours is a question with a definitive "no," but knowing the specific rhythm of your local warehouse can save you a lot of frustration.
- Check the App: The Costco app is surprisingly accurate for fuel hours. Use it before you drive ten miles out of your way.
- The Sunday Slump: Remember that Sundays are the shortest days. If it's dark outside on a Sunday, Costco gas is likely closed.
- The Holiday Rule: If the bank is closed for a federal holiday, check if Costco is too. They are more traditional than most retailers.
- Morning over Night: You have a much better chance of getting gas 15 minutes early than you do 5 minutes late.
If you really want to maximize the membership, aim for the "buffer hours"—that window after the pumps open but before the warehouse opens. You’ll get the price, the quality, and you won’t be left staring at a cold, dark screen in the middle of the night.
To stay ahead of the curve, set a recurring reminder on your phone for a weekly "fuel day" during the mid-week evening hours (Tuesday or Wednesday). These are historically the least busy times, ensuring you never have to gamble with the "after hours" lockout when your tank is dangerously low. If you frequently travel late at night, keep a $20 bill tucked behind your driver's license for an emergency splash of fuel at a 24-hour station, rather than relying on the strict Costco schedule.
