No. As of 2026, you must be an active Costco member to purchase fuel at any Costco gas station.
What if I forgot my Costco card for gas?
You can enter the gas station by showing a government-issued photo ID at the membership desk.
Just tell the attendant you left your card at home. They’ll verify your membership status in seconds—most locations in the U.S. handle this without a hitch. (International warehouses? Policies vary, so check with your local store before you drive up.)
Can I get Costco gas without a Costco card?
No, you cannot purchase fuel unless you are a current Costco member—with one exception: Costco Shop Cards.
Think of Shop Cards as the only loophole. These prepaid gift cards work at the pump without a membership, but regular non-member fuel purchases? Forget about it. You’ll still need to pre-authorize the pump with a valid debit card or a Shop Card.
Can anyone get fuel at Costco?
Only active Costco members can dispense fuel at Costco gas stations.
When you pull up to the pump, membership gets verified instantly. Have your card ready—or use the Costco app’s digital version on your phone. The pump also demands a pre-authorization payment method to confirm you’ve got the funds to cover your fill-up.
How much is Costco fuel?
As of April 2026, Costco fuel prices vary by location and fuel grade.
Take Costco Marsden Park in NSW, for example. E10 runs $1.307/L, U98 is $1.477/L, and Premium Diesel clocks in at $1.327/L. Honestly, this beats most supermarket fuel chains by 10–25 cents per litre. Always check your local pump or the website for the freshest numbers—prices shift faster than you’d think.
Can I still shop at Costco if I forgot my card?
Yes, Costco allows you to enter and shop even if you forgot your card.
Head straight to the membership desk. They’ll issue you a one-day temporary pass—good only for that visit. Without it or your actual card, you’re not checking out.
Can I go to Costco with my mom’s card?
Yes, any Costco member can bring up to two guests per visit.
Your guests can tag along inside, but they can’t buy anything unless their name’s on the account. You’ll need to show your card (or digital version) to get them through the door.
Can you buy at Costco without a card?
Non-members can shop on Costco.com and some Costco warehouses via curbside pickup.
Online orders are fair game for non-members, but expect a 5% surcharge. In-store shopping? Membership is usually required—except in places like Canada, where some local exceptions exist. Always double-check your warehouse’s rules.

Is Costco gas bad for your car?
No. Costco gas is high-quality and meets Top Tier detergent standards.
Kirkland Signature gasoline packs extra detergent additives that clean fuel injectors and cut engine gunk. Independent tests show it meets or beats Top Tier gasoline standards. Bottom line? Your engine runs cleaner and lasts longer compared to regular fuel.
Why is Costco gas cheaper?
Costco sells gas as a membership benefit to drive foot traffic and retain customers.
Membership fees bankroll over 70% of Costco’s gross profit. Rock-bottom fuel prices lure members inside, where they spend more on everything else. The razor-thin margins on gas get balanced out by membership revenue and in-store sales.
What documents do I need for Costco membership?
You typically need a government-issued photo ID, email confirmation, and possibly business or tobacco certificates.
- Costco membership confirmation (email or letter)
- Valid government-issued photo ID (e.g., driver’s license)
- For businesses: a business license or three forms of business ID
- For tobacco sales: a tobacco certificate (if applicable)
Rules can shift depending on location and membership type. Always verify with your local Costco warehouse or Costco’s website before you head over.
Can I get into Costco with the app?
Yes. The Costco mobile app can serve as your membership card for entry.
Grab the app from the App Store or Google Play, log in to your Costco.com account, and add your membership card to your phone’s digital wallet. Swipe the digital card at the entrance or the pump—no physical card needed.
Can I use someone else’s credit card at Costco?
No. Costco only accepts credit cards from the primary member or authorized users on the account.
Non-members? They’re stuck with debit cards or cash at the pump. In-store purchases by non-members aren’t allowed unless they’re ordering online. This keeps membership rules tight and cuts down on fraud.
Does Costco take your picture?
Yes. Costco requires a photo on your membership card for security.
That photo stops your card from being used by anyone else. Staff also rely on it to confirm your identity if there’s ever a mix-up or a lost card. It’s part of the standard membership verification process at every entrance and gas pump.
