About Costco

Costco Gas Stations are part of Costco Wholesale, a membership-based warehouse club headquartered in Issaquah, WA. In addition to bulk groceries and household goods, many Costco locations operate branded fuel stations that offer gasoline and, in some locations, diesel at discounted prices exclusively for members. These stations typically feature self-service pumps, pay-at-the-pump card readers, and are known for high fuel turnover, which many customers associate with fresher fuel.

A Costco fuel charge may appear on your bank or credit card statement when you purchase gasoline or diesel at a Costco Gas Station using a debit or credit card. You might see a single finalized transaction for the exact fuel amount, or first see a larger temporary authorization (often a round number such as $100–$150) that is later adjusted to your actual purchase. Charges can appear as one-time purchases, recurring patterns if you refuel frequently, or as pending authorizations that remain for a few days before dropping off or being replaced by the final amount.

If you’re unsure about a Costco gas charge, first compare the transaction date and location with your recent fuel stops and check any printed or emailed receipts from your Costco visit or your online bank/credit card activity for detailed merchant information. You can also log into your account at costco.com to confirm your membership status and recent orders, though fuel purchases may not appear in your online order history. For billing disputes or questions, contact your bank or card issuer, or reach Costco Member Services via the contact options listed at costco.com, and be ready to provide the date, amount, and last four digits of the card used. In most cases, billing issues are resolved by confirming the pump number, station address, and the authorization/settlement amounts on your statement.

Frequently Asked Questions

Why does my Costco gas purchase show a higher amount than the fuel I bought?

Costco Gas Stations, like many fuel retailers, place a temporary authorization hold on your card when you begin fueling—often a flat amount such as $100–$150. This hold ensures your card has sufficient funds but is not the final charge. Once you finish fueling, the transaction is adjusted to the exact amount of fuel you pumped, and the hold is released by your card issuer, typically within 1–3 business days (sometimes up to 5, depending on the bank).

What are typical charge amounts for Costco gas purchases?

Costco gas charges will match the total cost of the fuel dispensed, which is the posted price per gallon multiplied by the number of gallons pumped, plus any applicable local taxes already included in the per-gallon price. The most common patterns on statements are single, round-ish dollar amounts (for example, $35.72 or $64.10) that correspond to a full tank. You may also see a higher pending amount (such as $100 or $150) that later corrects to the exact purchase total once the transaction settles.

Why do I see both a pending Costco gas charge and a final charge on my statement?

When you purchase fuel at Costco, your card may first show a pending authorization for a set maximum amount. After the station finalizes the transaction for the actual fuel cost, your bank or card network updates the pending transaction. Some banks temporarily display both the original authorization and the final charge; the authorization should drop off automatically within a few business days without resulting in a double charge.

Do I need a Costco membership to be charged at a Costco gas station?

At most U.S. locations, you must have an active Costco membership card to purchase fuel at Costco Gas Stations, and the charge will appear under Costco or Costco Gas on your card statement. Some regions or jurisdictions may allow non-members to buy fuel due to local regulations, but the charge description will still show as Costco. If you’re seeing recurring fuel charges and share a membership or card with a family member, check whether an authorized household member is using the card at Costco gas.

How can I get a receipt or verify the details of my Costco gas transaction?

Receipts for Costco gas purchases are printed directly at the pump at the time of fueling, so your best record is the physical receipt you obtained there. If you did not print or keep the receipt, you can still verify the transaction by matching the date, time, and amount on your bank or credit card statement with your visit to the station. For further assistance, you can contact the specific Costco warehouse where the fuel station is located or reach Costco Member Services via the ‘Contact Us’ section at costco.com with the transaction date, amount, and the last four digits of the card used.

Can I cancel or reverse a Costco gas charge if I didn’t authorize it?

If you believe a Costco gas charge is fraudulent or was not authorized by you or an authorized user on your account, contact your bank or credit card issuer immediately to dispute the transaction and request a card replacement if needed. Then, reach out to Costco Member Services through costco.com or by calling the member service number on your Costco membership card and provide transaction details so they can investigate. Unauthorized fuel charges are typically handled through your card issuer’s dispute process, but Costco may assist in verifying location and time data from the station.

Does Costco offer any fuel subscription, membership tier pricing, or recurring billing for gas?

Costco does not sell fuel on a subscription basis and does not have automatic recurring billing specifically for gasoline. All fuel purchases are pay-per-transaction at the pump using a bank card, Costco Anywhere Visa, or other accepted payment methods. However, you must maintain an active Costco membership (usually billed annually) to use most Costco Gas Stations, and that membership fee itself will appear as a separate, recurring charge from Costco Wholesale, not from the gas station.

How do refunds or adjustments for Costco gas purchases work if there’s a billing error?

Because fuel is dispensed immediately, direct refunds at the pump are uncommon and usually require staff assistance at the associated Costco warehouse or station office. If you were clearly overcharged (for example, charged twice for a single fueling), bring your receipt and statement to the warehouse Member Services desk or contact them by phone so they can review the transaction. In many cases, your bank or card issuer will process a dispute or chargeback while Costco investigates, and any approved refund will appear as a credit on your card statement once processed.
