You're sitting in your car on South 341st Place, staring at the back of a silver SUV. Your low-fuel light just flicked on. It’s a Tuesday, and all you want is to fill up and get home. But if you don't know the federal way costco gas hours, you might end up staring at a closed gate or, worse, a forty-minute wait that drains your patience faster than your tank.
Costco gas is a religion in Washington. With gas prices in the Puget Sound area often sitting significantly higher than the national average, saving thirty or forty cents a gallon isn't just a perk; it’s a financial strategy. The Federal Way location, situated right off Enchanted Parkway S, is one of the busiest hubs in the region. Honestly, it’s a bit of a logistical nightmare if you time it wrong.
Most people assume the gas station opens and closes with the main warehouse. That’s the first mistake.
When Can You Actually Get Gas in Federal Way?
The federal way costco gas hours are designed for the early birds and the night owls, not just the mid-day shoppers. On weekdays, from Monday through Friday, the pumps generally open at 6:00 AM. They stay open until 9:30 PM. This is a massive window compared to the warehouse itself, which doesn't open its doors until 10:00 AM.
Weekends change the game. On Saturday, you're looking at a 7:00 AM start time with an 8:00 PM cutoff. Sunday is the shortest window, typically opening at 7:00 AM and shutting down at 7:00 PM.
If you show up at 9:31 PM on a Wednesday, the lights will be on, but the pumps will be dead. There is no "grace period." The attendants are efficient, and once that clock hits the mark, the lanes are blocked. It’s frustrating, but it’s how they keep the traffic flow from bleeding into the residential and commercial areas nearby.
A Quick Breakdown of the Schedule
- Monday – Friday: 6:00 AM to 9:30 PM
- Saturday: 7:00 AM to 8:00 PM
- Sunday: 7:00 AM to 7:00 PM
Keep in mind that holidays are the ultimate "gotcha." Costco is famous for being closed on major holidays like New Year’s Day, Easter, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. If the warehouse is closed for a holiday, the gas station is closed too. Don't be the person idling at the entrance on July 4th wondering why it's so quiet.

The Secret to Avoiding the Federal Way Congestion
Federal Way traffic is weird. You have the Commons mall nearby, Wild Waves down the road, and a constant stream of commuters heading toward I-5. Because of this, the Costco gas station becomes a bottleneck.
If you go between 4:00 PM and 6:30 PM on a weekday, you're going to wait. It’s inevitable. You’ll be sitting there, watching the person in front of you struggle with their membership card, feeling your blood pressure rise.
The "Golden Window" is 6:00 AM to 8:00 AM on weekdays. Most people are rushing to work and don't think they have time to stop. If you can swing it, filling up before the warehouse opens at 10:00 AM is the single best way to get in and out in under five minutes. Once the main store opens, the parking lot traffic merges with the gas station traffic, and it becomes a chaotic dance of Honda Odysseys and Ford F-150s.
Another pro tip: the late-night run. After 8:30 PM on a Tuesday or Wednesday, the crowds thin out significantly. The "after-work" rush has gone home to eat dinner, and the "night-time" shoppers are already inside the warehouse.
Why This Specific Location Matters
The Federal Way Costco (Warehouse #67) isn't just any warehouse. It’s a focal point for people living in Milton, Edgewood, and even parts of Auburn. Because it’s right off Highway 161, it attracts a much larger radius of drivers than a neighborhood station.
The fuel quality here is TOP TIER™ certified. This isn't just marketing fluff. Brands like Costco, Chevron, and Shell invest in detergent additives that help prevent carbon buildup in your engine. When you're looking at the federal way costco gas hours, you're not just looking for a cheap fill-up; you're looking for high-quality 87 or 92 octane fuel that keeps your car running longer.

Many local mechanics in the South End actually recommend Costco fuel because of the turnover. Because they sell so much gas, the fuel in the underground tanks is always fresh. It doesn't sit around absorbing moisture like it might at a derelict station on the corner of Pacific Highway.
Managing the Lane Logistics
Have you ever noticed the long hoses? Seriously, you don't need to wait for a pump on the side of your gas tank's opening. Costco’s dispensers have extra-long, retractable hoses. You can pull into any lane, pull that hose across the back of your car, and fuel up.
Yet, every single day in Federal Way, people wait in a line ten cars deep for a "left-side" pump while the "right-side" pumps are wide open. Don't be that person. Grab the open spot, pull the hose, and get moving.
Membership and Payment Realities
You can't just roll up with a handful of 20-dollar bills. This is a common point of confusion for people who aren't regular members. To use the pumps during the federal way costco gas hours, you need a valid membership card.
The system is automated. You scan your membership, then you swipe your payment card.
Costco only accepts Visa credit cards or most debit cards. If you’re trying to use a Mastercard or an Amex, you’re out of luck. The only exception is the Costco Shop Card (their version of a gift card). If you have a Shop Card, you don't actually need a membership to buy gas, but you do need to get that card from a member beforehand.

Dealing with Maintenance and Downtime
Occasionally, you'll show up during posted hours and find yellow tape over the pumps. This usually happens for two reasons: filter changes or software updates.
Costco changes their fuel filters more frequently than many other stations to ensure the "Top Tier" standard. Usually, they do this one or two pumps at a time, but occasionally the whole system goes down for a reboot. If you see an attendant in a neon vest waving people away, don't argue. There’s a Safeway and a Fred Meyer nearby, though you'll pay a premium for the convenience of not waiting.
Is the Savings Actually Worth the Wait?
Let's do some quick math. If the Federal Way Costco is $0.40 cheaper than the Shell station by the freeway, and you have a 15-gallon tank, you're saving $6.00.
If you wait 30 minutes in line, you're basically valuing your time at $12.00 an hour. For some, that’s a win. For others, it’s a waste of a Saturday morning. This is why knowing the hours and the "low-flow" times is vital. You want that $6.00 savings without the 30-minute tax on your life.
Environmental Factors in the Northwest
We live in Washington. It rains. A lot. The Federal Way fuel station is covered, which sounds like a small detail until you're trying to fill up during a November downpour. The canopy is high enough to accommodate most large Sprinter vans and trucks, but always be mindful of your clearance if you have a roof rack or a lifted rig.
Real-World Strategies for Federal Way Residents
- Check the App: The Costco app often lists the current gas prices for the Federal Way location. Prices can change daily, sometimes even twice a day if the market is volatile.
- The Monday Morning Rule: Avoid Monday mornings if possible. Everyone is "topping off" for the work week.
- Use the South Entrance: Entering from 348th St can be a nightmare. Try coming in from the back side via 1st Ave S or the smaller side streets to avoid the main intersection gridlock.
- Have Your Card Ready: Don't be the person who starts digging through their wallet only after they reach the pump. Have your membership and your Visa in your hand before you put the car in park.
The federal way costco gas hours are consistent, but the experience varies wildly based on your timing. If you treat it like a mission—get in early, use the long hose, and pay with the right card—you'll save hundreds of dollars a year. If you show up at noon on a Sunday, well, hopefully you have a good podcast to listen to.
Actionable Steps for Your Next Fill-Up
- Verify the day: Confirm if it's a weekday (9:30 PM close) or a weekend (shorter hours).
- Check your wallet: Ensure you have a Visa or a debit card; skip the cash and other credit brands.
- Target the window: Aim for before 9:00 AM or after 7:30 PM for the fastest service.
- Ignore the "Side": Pull into the first available pump regardless of which side your gas cap is on; those hoses reach further than you think.
- Watch the Calendar: If a holiday is approaching, fill up two days early to avoid the "pre-holiday" panic lines.
By following these specific local insights, you turn a chore into a quick pit stop. The Federal Way station is a beast, but it's a manageable one if you know the rhythm of the neighborhood.
