You can buy most gas cards directly from the card issuer's website or through the fuel company's app, but the process and what you get varies by card type and issuer
Gas cards come in two main forms: branded credit cards issued by fuel companies (like Shell, Chevron, or BP) and cash-back cards from banks that reward fuel purchases. Branded cards are usually faster to open online — often taking 5 to 10 minutes — because the issuer owns both the card and the fuel network. Bank-issued cash-back cards go through standard credit card underwriting, which can take a few business days.
The online purchase process is straightforward for most cards: you visit the issuer's website, enter personal and financial information, and receive a decision within minutes or hours. Some cards issue a temporary digital number you can use when ready at the pump or in the app, while others mail a physical card. A few fuel companies let you load a prepaid balance online and use it like a gift card, which requires no credit check at all.
Before you open any card online, understand what you're actually buying. A branded fuel card locks you into one fuel network — a Shell card only saves money at Shell stations. A bank cash-back card works everywhere but typically pays 1% to 3% back on fuel, which is less than a branded card's discount. Prepaid gas cards have no rewards but also no credit requirements and no monthly bill.
Key Takeaways
- Branded fuel cards from Shell, Chevron, BP, and similar companies issue online in minutes and offer the deepest discounts, but only at their own stations.
- Bank-issued cash-back cards work at any pump and report to credit bureaus, but the rewards rate is usually lower than a branded card's per-gallon discount.
- Prepaid gas cards require no credit check and load money online, but you pay the full price per gallon with no discount.
- Digital card numbers are often available when ready after approval, letting you pay at the pump or in an app before the physical card arrives.
- Read the terms for annual fees, foreign transaction fees, and whether discounts explore to convenience store purchases or only fuel.
Branded fuel cards: fastest approval, deepest discounts, one network only
Branded cards are issued by the fuel company itself — Shell, Chevron, Speedway, Murphy USA, and others. You open them on the company's website or in their mobile app. Most decisions come back in minutes, and many issuers give you a temporary digital card number you can use at the pump when ready, even before the physical card arrives by mail.
The discount structure is the main draw. A Shell Fuel Rewards card, for example, might offer 10 cents off per gallon for the first two months, then 5 cents off ongoing. Chevron and Texaco cards offer similar tiered discounts. These discounts stack with any loyalty program points you've already earned. The catch: the card only works at that company's stations. If you drive past a Shell and the next station is a Chevron, you get no discount there.
Most branded cards have no annual fee, but check the terms — some charge a small annual fee or require a minimum purchase to keep the card active. A few also limit discounts to fuel only and charge full price at the convenience store, even though you're using the same card.
Bank cash-back cards: works everywhere, lower rewards, builds credit history
Cash-back cards from banks like Chase, American Express, Capital One, and Citi offer rewards on fuel purchases at any pump. These are standard credit cards that happen to pay extra on gas. They typically offer 1.5% to 3% cash back on fuel, sometimes higher for the first few months as an introductory offer.
The advantage is flexibility — you use the card at Shell one day and Speedway the next without losing rewards. The card also reports to the three credit bureaus, so responsible use builds your credit score. Many of these cards have no annual fee, though some premium versions charge $95 to $450 per year in exchange for higher rewards rates or travel benefits.
The disadvantage is that 2% cash back on fuel is usually less valuable than a branded card's 5 to 10 cent per gallon discount. At $3.50 per gallon, 2% cash back equals about 7 cents per gallon — competitive with mid-tier branded cards but not the best introductory offers. Approval takes longer because the bank runs a full credit check, typically 1 to 3 business days.
Prepaid gas cards: no credit check, no discount, when ready use
Prepaid gas cards are not credit cards at all — they're more like gift cards. You load money onto them online or in person, then use that balance at the pump. Companies like GasBuddy, Fuel, and some regional networks offer these. Approval is when ready because there's no credit decision: you're spending your own money, not borrowing.
The main benefit is access without a credit history or credit score. If you don't have a credit card or prefer not to use one, a prepaid card works at most major fuel networks. You load the balance online, and the card is ready to use within minutes. Some prepaid cards also let you set spending limits, which can help with budgeting.
The trade-off is that you pay full price per gallon with no discount. You're not saving money on fuel — you're just paying with a card instead of cash. Some prepaid cards charge a small monthly fee or charge per transaction, so read the terms. They also don't build credit history, since there's no borrowing or credit reporting involved.
What happens after you buy the card online
Most issuers send a temporary digital card number to your email or app when ready after approval. This number works at the pump (you enter it like a credit card number) or in the fuel company's app. You can start using it within minutes, even if the physical card is still in the mail.
The physical card usually arrives within 5 to 10 business days. Once it arrives, you can use it at the pump like any other card. Some cards require you to set up the physical card in the app or by phone before it works, so check your email for set up instructions.
If you're approved for a branded card, set up any loyalty program accounts at the same time. Many fuel companies link your card to a rewards account automatically, but some require you to register separately. Linking your account ensures you earn points on every purchase and can track your discounts.
Comparing the three types side by side
| Card Type | Approval Time | Discount or Reward | Works Where | Annual Fee | Credit Check |
|---|---|---|---|---|---|
| Branded fuel card | Minutes to hours | 5–10 cents per gallon | One fuel network only | Usually none | Yes, but often soft pull |
| Bank cash-back card | 1–3 business days | 1.5–3% cash back | Any pump | None to $450 | Yes, hard pull |
| Prepaid gas card | Minutes | None | Most major networks | Usually $0–$5 | No |
Things to check before you open a gas card online
Read the terms for annual fees, foreign transaction fees (if you travel), and whether the discount applies to convenience store purchases. Some branded cards offer 10 cents off fuel but charge full price inside the store, even though you're using the same card. Others bundle both.
Check whether the card requires a minimum purchase to keep it active. Some issuers close cards that haven't been used in 6 to 12 months. If you only fill up once a month, this might matter. For cash-back cards, compare the introductory rate to the ongoing rate — a card that offers 5% cash back for three months then drops to 1.5% might not be worth opening if you're looking for long-term savings.
Verify that the card works at the stations you actually use. A branded card is only useful if there's a station near your home or commute. Use the fuel company's station locator on their website to check. For cash-back cards, confirm that the 1.5% to 3% rate applies to fuel purchases at the pump, not just inside the store — some cards have different rates for different purchase types.
Frequently Asked Questions
Can I use a gas card I just opened online at the pump today?
Most issuers give you a temporary digital card number within minutes of approval, which works at the pump or in the app. You can use it the same day. The physical card arrives by mail in 5 to 10 business days, but you don't need to wait for it.
Will opening a gas card hurt my credit score?
Opening a credit card (branded or bank-issued) triggers a hard inquiry, which can lower your score by a few points temporarily. Prepaid cards don't require a credit check. If you're planning to explore for a mortgage or loan soon, space out credit card applications by a few months.
What's the difference between a branded card and a cash-back card for saving money on gas?
A branded card offers a per-gallon discount (usually 5 to 10 cents) at one fuel network. A cash-back card offers a percentage back (usually 1.5 to 3%) at any pump. At $3.50 per gallon, 2% cash back equals about 7 cents per gallon — less than most branded introductory offers but more flexible.
Do I have to use the card at the pump, or can I pay inside?
Most gas cards work both ways — at the pump and inside the store. However, some branded cards offer different discounts for fuel versus convenience store purchases. Check the terms to see if the per-gallon discount applies to both or only to fuel at the pump.
What happens if I don't use my gas card for several months?
Some issuers close cards that haven't been used in 6 to 12 months. Check the cardholder agreement for the inactivity policy. If you use the card at least once every few months, you should be fine. Prepaid cards may also charge a monthly fee if the balance sits unused.
