Costco gas is usually 20–30 cents cheaper per gallon than nearby stations. That adds up fast. But if you’ve never fueled up there before, the process isn’t always obvious. This guide walks you through everything — membership rules, payment tricks, pump etiquette, and fuel quality — so your first visit goes smoothly.
Do You Need a Membership to Get Gas at Costco?
Yes. You need an active Costco membership to buy gas at Costco. When you pull up to the pump, you’ll need to scan or swipe your membership card before the pump activates. No card, no gas — it’s that simple.
According to Costco’s official gas Q&A, the pumps are private facilities reserved strictly for paying members.
What If You’re Not a Member?
There’s one workaround: a Costco Shop Card. It’s a prepaid gift card that lets non-members pump gas just like a regular member. Here’s the catch though:
- Only active members can buy or reload Shop Cards
- Non-members can’t purchase them independently
- Once the balance runs out, a non-member can’t reload it
- Digital Shop Cards don’t work at the pump — you need the physical plastic card
So if a friend or family member with a membership buys you a Shop Card, you’re good to go. If the fuel total exceeds the card balance, you can pay the difference with a Visa card or PIN debit.
Does Your Membership Tier Affect Anything?
Not really at the pump. Both Gold Star and Executive memberships get you access to the fuel station. One thing worth knowing: Executive members don’t earn the 2% cash-back reward on gas. Motor fuel is explicitly excluded from that annual reward calculation. So don’t expect a rebate on fuel — the savings come purely from the lower price per gallon.
What Payment Methods Does Costco Accept for Gas?
Costco gas stations only accept specific payment methods. Showing up with the wrong card wastes time and creates awkward pump moments.
Here’s what works — and what doesn’t:
| Payment Type | Accepted? | Notes |
|---|---|---|
| Visa credit cards | ✅ Yes | All Visa-branded cards, including international |
| Mastercard / Amex / Discover | ❌ No | Rejected at the pump — no exceptions |
| PIN-based debit cards | ✅ Yes | Must enter your PIN |
| Apple Pay / Google Pay | ✅ If Visa or PIN debit is linked | Wallet must connect to an approved card |
| Physical Costco Shop Card | ✅ Yes | Works for non-members too |
| Cash | ❌ No | Completely prohibited at the pump |
| Checks | ❌ No | Not accepted |
If you only carry cash, park your car, head inside, buy a Shop Card at the customer service desk with your cash, then return to the pump and use the card.
The Fastest Way to Pay
The Costco Anywhere Visa Card by Citi is the smoothest option. It combines your membership authentication and payment into one tap. The pump recognizes both at the same time — no extra scanning required. It also earns strong cash-back on fuel purchases up to an annual spending cap.
How to Use the Costco App at the Gas Pump
The Costco mobile app makes the whole process faster. Here’s what it does:
- Stores your digital membership card
- Shows live gas prices at nearby locations
- Lets you link a Visa card for payment
- Auto-populates your card on the lock screen when you’re near the station (using geofencing)
When you pull up to the pump, open the app and scan the QR code on the pump’s reader. It authenticates your membership and charges your linked Visa in one scan. Alternatively, scan the QR code for membership and tap Apple Pay or Google Pay for payment — as long as it’s connected to a Visa or PIN debit account.
Reddit users confirm this single-tap method works seamlessly at most locations.
Step-by-Step: How to Get Gas at Costco
Here’s the exact process from pulling in to pulling out:
1. Find your local Costco gas station
Use the app or Costco’s website to confirm your nearest warehouse has a fuel station and check current prices.
2. Join the queue
Traffic flows one direction only. Follow the lanes — don’t try to go the wrong way.
3. Pull forward to any open pump
Watch for green/red overhead indicator lights. Green means open. Pull into the first available spot, even if it’s on the “wrong” side of your car (more on that below).
4. Authenticate your membership
Swipe your card, tap your Costco Anywhere Visa, or scan the QR code in the app.
5. Select your payment method
Follow the prompts to confirm payment.
6. Choose your fuel grade
Most members pick Regular. Premium is available too. Select it and fill up.
7. Replace the nozzle and go
Once the pump clicks off, don’t top off. Remove the nozzle, close your fuel door, and move your car immediately to free up the pump.
Skip the printed receipt if you can — it saves time and keeps the line moving.
Understanding the Pump Layout (and the Long Hoses)
Costco gas stations look different from regular stations — and there’s a reason for that.
Why Costco Uses Extra-Long Hoses
You’ve probably noticed the hoses at Costco pumps look unusually long. They’re engineered specifically to reach both sides of any vehicle. That means your gas cap can be on the driver’s side or passenger’s side — it doesn’t matter. Pull into the nearest open lane.
Most people worry the hose will scratch their car. The rubber compound won’t damage your paint if you position your car correctly. Pull far enough forward so the hose drapes behind your bumper, not over the roof or side panels.
Why don’t other gas stations do this? International Fire Code limits hose length to 18 feet unless specific clearances are granted. Costco’s standalone pump islands are positioned far enough from the main building to qualify — a structural advantage that small urban stations don’t have.
The Green Light System
Many Costco stations now have overhead red and green indicator lights above each pump:
- 🔴 Red = pump is occupied
- 🟢 Green = pump is open, move to it now
If the pump in front of you is empty and green, pull around the car ahead of you and take it. This isn’t cutting the line — it’s exactly what the attendants expect you to do. Sitting still while a green pump sits empty frustrates everyone behind you and slows the whole station down.
Is Costco Gas Actually Good Quality?
Yes — and it’s not just marketing.
Costco sells Kirkland Signature Gasoline, which is certified TOP TIER gasoline. That’s a standard created by major automakers — including GM, Ford, and Volkswagen — because the federal EPA minimum for detergent additives wasn’t strong enough to protect modern engines.
Here’s what makes it stand out:
- Kirkland gas contains roughly 5x the federal minimum concentration of detergent additives
- Those additives actively clean existing carbon deposits from intake valves — not just prevent new ones
- Clean injectors mean better fuel atomization, which preserves your car’s fuel economy
- The additive blending happens on-site, injected into the underground tank during delivery — not at a third-party refinery
Over time, consistently using TOP TIER fuel can improve engine startup, reduce rough idling, and lower tailpipe emissions. TOP TIER certified brands all meet this elevated standard, and Costco is firmly on that list.
If your location offers diesel, it’s covered too. Kirkland Signature Diesel meets TOP TIER Diesel standards and includes additives for lubricity, cold-weather performance, and injector protection — important for modern high-pressure diesel engines.
Special Cases: New Jersey, Oregon, and International Visitors
New Jersey Members
New Jersey has unusual fuel laws. For nearly 18 years, non-members could buy Costco gas there due to a state directive. That ended in July 2022. Costco reinstated the membership requirement after reviewing the actual statutes — and the state confirmed it was legal.
One exception: the Mount Laurel, NJ location still allows non-members. A municipal zoning condition from when the pumps were built requires public access — and that local agreement overrides corporate policy.
Also remember: New Jersey law requires an attendant to pump your gas. You don’t touch the nozzle there.
Oregon Members
Oregon banned self-service fueling for 72 years. That changed in August 2023 with Oregon House Bill 2426, which legalized self-service statewide — with conditions:
- Rural counties: Up to 100% of pumps can be self-service
- Urban/suburban counties: Max 50% self-service; the other 50% must have attendants at all times
So depending on which Oregon Costco you visit, you may or may not pump your own gas.
International Visitors
Foreign cards often hit two snags at Costco pumps:
- The pump asks for a ZIP code as fraud prevention — international cards usually don’t have one
- Non-Visa cards (like Mastercards issued abroad) get rejected outright due to Costco’s Visa exclusivity
If you’re visiting from abroad, grab a physical Shop Card inside before heading to the pumps. That sidesteps both problems.
A Few Quick Rules to Remember
- Don’t idle in the station — attendants enforce this
- Don’t top off after the nozzle clicks — it risks damaging your evaporative emissions system and slows the queue
- Don’t block the pump after you’re done — pull forward immediately
- Check the app for live prices before driving over — Costco prices update throughout the day
Getting gas at Costco takes a little practice the first time. Once you know the card rules, the payment system, and how the traffic flow works, it becomes one of the most efficient fuel stops you’ll make — cheaper per gallon and faster than most people expect.
