You’re sitting in that brutal line on Enchanted Parkway South. You see the red and white sign. You just want to fill up before the workday ruins your vibe, but the lights are off. It happens. People constantly get caught off guard because they assume the gas station opens when the warehouse does. It doesn't.
Actually, knowing the Costco gas hours Federal Way location operates on is the difference between a five-minute breeze and a twenty-minute headache.
Most folks in South King County treat Costco like a religion. We go there for the rotisserie chicken, the oversized packs of paper towels, and definitely the fuel. But the Federal Way location—technically Warehouse #67—has a rhythm of its own. It’s tucked right near the Commons mall and the transit center, making it one of the busiest hubs in the region. If you show up at 10:00 AM on a Saturday thinking you'll "beat the rush," you've already lost the game.
The Actual Schedule You Need to Bookmark
Let's get the numbers out of the way. According to Costco's official warehouse data for the Federal Way 1st Ave South location, the fuel station operates on a much wider window than the main store.
Monday through Friday, the pumps wake up at 6:00 AM and shut down at 9:30 PM.
Saturday is a bit tighter. They still open at 6:00 AM, but they cut the power at 7:00 PM.
Sundays? That's the shortest window. You're looking at 7:00 AM to 7:00 PM.

Why does this matter? Because the warehouse itself doesn't open until 10:00 AM on weekdays. That four-hour gap between 6:00 AM and 10:00 AM is the "golden hour." It’s when the commuters heading toward Seattle or Tacoma pull in, swipe their fob, and leave before the minivan brigade arrives for the grocery grand prix. Honestly, if you aren't using those early hours, you're choosing to suffer in line.
Why Federal Way is Different from Fife or Covington
Every Costco gas station feels the same, right? Wrong. The Federal Way layout is notoriously tricky because of how the entrance interacts with the surrounding traffic lights. If you're coming from the north, you're fighting mall traffic. From the south? You're dealing with the Highway 18 merge madness.
The Costco gas hours Federal Way regulars depend on are strategically set to catch the early birds. Unlike the Covington location, which can feel a bit more "suburban-quiet" during the mid-morning, Federal Way is a high-volume transit pipe.
I’ve seen the line wrap around the tire center and almost spill back onto the main road. The staff there are efficient—kinda like air traffic controllers—but they can’t fix physics. There are only so many pumps.
One thing that surprises people: the "long hose" trick. Costco's gas hoses are designed to reach both sides of your car. You’ll see people waiting in a line of ten cars for a left-side pump because their gas tank is on the left. Meanwhile, the right-side pumps are empty. Pull up to the right side. Pull the hose over. It reaches. It feels weird the first time, like you're stretching a giant rubber band over your trunk, but it works perfectly. It saves you ten minutes of idling.
Maintenance and "Hidden" Closures
Ever pull up during "open" hours only to find orange cones everywhere? It’s the worst.

Usually, this happens for one of two reasons. First, the fuel delivery truck. When that massive tanker pulls in to refill the underground vats, they often have to block off sections of the lanes for safety. It’s a literal "wrong place, right time" situation.
Second, the sensors. Costco uses high-tech leak detection and vapor recovery systems. If a sensor trips, that pump—or the whole station—goes dark until a technician clears it. While the Costco gas hours Federal Way site lists 9:30 PM as the closing time, they start tapering off the lines about five or ten minutes prior. If you roll in at 9:29 PM with a bone-dry tank, you’re gambling with your evening.
The Membership Factor and Payment Realities
You can't just roll up with a handful of 20s. This isn't the corner station.
You need that membership card. Or, if you're living in 2026 like the rest of us, the digital membership card on the Costco app. The scanners at the Federal Way pumps can be a little finicky with screen brightness, so crank yours up before you hold it to the glass.
Payment is strictly Visa credit cards or most PIN-based debit cards. No Mastercard. No Amex. No "I'll pay you next Tuesday." If you're a non-member, the only way you're getting gas is if a member gives you a Costco Shop Card. It’s a neat little loophole, but honestly, with the price spread between Costco and the Shell station down the street, the membership usually pays for itself in about ten fill-ups.

If you’re going for gas, plan the rest of your life around it.

- The Mid-Week Sweet Spot: Tuesday and Wednesday nights after 8:00 PM. The "after-work" rush has gone home to eat dinner, and the late-night crowd hasn't arrived yet.
- The Morning Sprint: 6:15 AM. You’ll see the same group of contractors and commuters. It’s a silent, efficient brotherhood of people who just want cheap 91 octane.
- Avoid the "Lunch Crunch": Between 11:30 AM and 1:30 PM, the gas station becomes a chaotic extension of the food court run. Don't do it to yourself.
Federal Way is a melting pot. You’ve got people coming from Northeast Tacoma, Des Moines, and even Milton just to hit this specific warehouse. It adds a layer of congestion that you don't find at the newer, more isolated locations.
Real-World Price Dynamics
We keep talking about the Costco gas hours Federal Way provides, but let's talk about the why. The price.
Historically, Costco stays about 20 to 40 cents below the local average. In a town like Federal Way, where we have a lot of commuters hitting I-5 every day, that's hundreds of dollars a year. They sell TOP TIER™ detergent gasoline. This isn't just marketing fluff. It’s a real standard that means the gas has more additives to keep your engine's intake valves clean.
Does it make your car a race car? No. Does it stop your engine from gunking up over 100,000 miles? Most mechanics say yes.
Actionable Steps for Your Next Fill-Up
To make the most of your stop at the Federal Way Costco gas station, follow this checklist:
- Check the App First: The Costco app actually shows the current gas price for the Federal Way location. Prices can shift overnight based on the market.
- Aim for the "Golden Hours": 6:00 AM to 8:00 AM or after 8:00 PM on weekdays.
- Check Your Lane: Look for the "Empty Lane" lights above the pumps, though in Federal Way, they’re usually all green because someone is always there.
- Use the Right-Side Pumps: Don't be afraid to pull the hose across your vehicle. It is designed for this exact purpose.
- Keep Your Fob Handy: Fumbling for your wallet at the pump is how the line slows down. Be the person who is ready to scan and go.
The Federal Way location is a beast, but it's a manageable one. Respect the clock, understand the layout, and stop fighting for the left-side pumps. You'll be back on 1st Ave before your coffee gets cold.
