The short answer
This is a pre-authorization hold from a Murphy USA gas station (often located in Walmart parking lots). It is a temporary pending transaction that verifies you have enough funds to purchase a full tank of gas.
Why Murphy USA holds your funds
A charge showing MURPHY7811ATWALMART on your bank statement represents a temporary pre-authorization hold from a Murphy USA fuel station located outside a Walmart store. Gas stations place this temporary hold before pumping fuel to verify your card has sufficient funds.
These holds typically range from $75 to $150 and appear as pending charges on your account. Murphy USA does not actually keep this money; the hold drops off automatically once the station transmits your exact fuel purchase total to your bank.
If a pending hold remains on your account longer than a few business days, contact your bank customer service line, as only financial institutions can manually release pending authorizations. To avoid large holds in the future, prepay with the cashier inside the kiosk for an exact dollar amount. Keeping close track of your monthly statements ensures complete financial security and prevents unexpected surprises from recurring charges.
How to handle pending gas holds
These holds can be frustrating, especially if they cause your checking account to dip into the negative and incur overdraft fees.
- Wait for the charge to clear The hold is legally required to fall off once the final transaction posts. This process typically takes 1 to 3 business days.
- Call your bank's support line If the hold persists longer than 3 business days, call your bank (not Murphy USA). Only your financial institution can manually release a pending authorization.
- Avoid holds by paying the cashier If you hand your card to the Murphy USA attendant inside the kiosk and specify a dollar amount (e.g., $40 on pump 3), the system will only authorize exactly $40.
