Quick Answer: Yes, Costco gas stations are open on Sundays. Most locations operate 6am-7:30pm on Sundays as of November 2025. This gives you over 13 hours to fuel up on weekends. Sunday hours are slightly shorter than weekday schedules (6am-10pm Monday-Friday) but still provide convenient access.

Sunday Hours at Costco Gas Stations
Costco gas stations welcome members every Sunday with adjusted operating schedules. After extending hours nationwide in February 2025, Costco improved weekend access while maintaining competitive fuel prices that average 53 cents below competitors.
Standard Sunday Schedule (2025):
Most Costco gas stations operate 6:00am to 7:30pm on Sundays. This provides ample time for weekend errands, pre-work fueling, or topping off before the Monday commute. The 13.5-hour window accommodates various schedules without the late-night closing of weekdays.
Regional Variations:
Some locations adjust hours based on local demand. California and Hawaii stations may have slightly different schedules due to state regulations or market conditions. Always verify your specific station’s hours before visiting, especially if traveling to a new area.
Sunday hours differ from Saturday (6am-8:30pm) and weekday schedules (6am-10pm Monday-Friday). The reduced Sunday evening closing time reflects typical member shopping patterns and operational efficiency.
Complete Weekly Hours Schedule
Understanding Costco’s full weekly gas station schedule helps you plan fuel stops around your routine. The extended hours implemented in early 2025 significantly improved member convenience.
Standard Operating Hours (2025):
- Monday-Friday: 6:00am – 10:00pm (16-hour window)
- Saturday: 6:00am – 8:30pm (14.5-hour window)
- Sunday: 6:00am – 7:30pm (13.5-hour window)
These extended hours represent a major improvement from previous schedules. CEO Ron Vachris confirmed the February 2025 changes led to two all-time highest gallon sales weeks in April 2025. Members appreciate the flexibility, especially early morning and late evening access.
Why Hours Vary by Day:
Costco adjusts gas station hours based on member demand patterns. Weekdays see longer hours to accommodate commuters. Weekend schedules balance service availability with operational costs. Sunday’s earlier closing reflects lower evening traffic compared to Saturday.
When Costco Gas Stations Are Closed
While Costco gas stations maintain generous operating hours, they close completely on major holidays. Planning around these closures prevents disappointing trips when your tank runs low.
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)
These seven holidays mean complete gas station closures nationwide. Costco aligns gas station and warehouse closures on these dates. If a holiday falls on Sunday, the gas station remains closed that entire day.
Planning Around Holidays:
Check tomorrow’s hours before holiday weekends. Many members fuel up the day before major holidays. This creates longer lines, so arrive early or visit late evening for faster service.
Best Times to Visit on Sunday
Strategic timing makes Sunday fuel stops faster and more pleasant. Understanding traffic patterns helps you avoid crowds while still enjoying Costco’s competitive pricing.
Optimal Sunday Time Slots:
- Early Morning (6am-8am): Shortest waits of the day – many members sleep in on Sundays
- Late Afternoon/Evening (6pm-7:30pm): Crowds thin as closing approaches – excellent choice for quick fill-ups
- Right at Opening (6am): Almost empty pumps if you’re an early riser
Times to Avoid on Sunday:
- Mid-Morning (9am-11am): Peak Sunday shopping time creates long lines
- Early Afternoon (12pm-3pm): Families fueling up during weekend errands
- After Warehouse Opening: Members combine shopping with gas purchases
Sunday evenings after 6pm offer particularly good service. Most weekend errands finish by then, leaving pumps relatively open. You can fuel up quickly before the station closes at 7:30pm.
Membership and Access Requirements
Valid Membership Required:
You must have a current Costco membership to purchase gas any day of the week, including Sundays. Both Gold Star and Executive members can use gas stations. The pump validates your membership card before authorizing payment.
Digital Membership Cards:
Use your digital membership card from the Costco app on Sundays. No need to carry your physical card—just scan from your phone at the pump. This convenience works across all operating days.
Non-Member Options:
Costco Shop Card holders can purchase gas without a membership. If someone gives you a Costco Shop Card, you can use it at gas stations even on Sundays without your own membership.
Sunday Payment Options
Costco gas stations accept the same payment methods on Sundays as any other day. Understanding accepted payments prevents delays at the pump.
Accepted Payment Methods:
- Visa credit and debit cards – Primary payment option
- PIN debit cards – Most major banks accepted
- Costco Shop Cards – Pre-loaded gift cards work at pumps
- Mobile payments – Apple Pay and Google Pay (linked to Visa)
- Costco Anywhere Visa Card – Earns 4% cashback on gas purchases
NOT Accepted at Pumps:
- Cash (not accepted at pumps any day)
- Mastercard credit cards
- American Express
- Discover cards
- Checks
Cash Workaround:
While pumps don’t accept cash, you can purchase Costco Shop Cards with cash inside the warehouse. These pre-loaded cards then work at gas pumps on Sundays or any day. This provides a cash-to-gas pathway for members who prefer not using cards.

Comparing Sunday to Other Days
Sunday vs Saturday Service:
Saturday offers one additional hour of evening service (closing at 8:30pm vs 7:30pm Sunday). However, Sunday mornings typically see lighter traffic. If you need late evening access, Saturday provides more flexibility.
Sunday vs Weekday Access:
Weekdays offer significantly longer hours with 10pm closing times. This gives commuters late-evening options after work. Sunday’s 7:30pm closing is 2.5 hours earlier but still accommodates most weekend schedules.
Price Consistency:
Gas prices remain the same on Sundays as weekdays. You don’t pay extra for weekend convenience. Costco updates prices based on market conditions, not day of week. Check current per-gallon costs any day through our tracker.
Quality and Service on Sundays
Consistent Fuel Quality:
Sunday fuel quality matches every other day of the week. Kirkland Signature gasoline meets TOP TIER™ standards seven days weekly. Enhanced deposit control additives protect your engine regardless of when you fill up.
Self-Service Convenience:
All Costco gas stations operate as self-service locations. Extra-long hoses reach either side of your vehicle, making positioning easier. Sunday service matches weekday efficiency with the same pump technology and payment systems.
Station Cleanliness:
Many locations perform maintenance and cleaning during Sunday evening hours after 7:30pm closing. This means Sunday morning often offers particularly clean facilities and well-maintained pumps.
