Best Credit Cards for Gas Stations in 2025 (Ranked by Real Cash Back)

The average American household spends about $2,100 a year on gas. At 1% cash back — the default on most cards — that's $21 back. Swap to a card that earns 3–5% on gas and you're looking at $63–105 annually, plus the same card typically earns well on other categories too. The math is simple; the execution is where most people leave money on the table.

Here's the honest ranking of the best credit cards for gas station purchases in 2025, including the fine print that matters.

The Best Cards, Explained

1. Citi Custom Cash℠ — Best No-Annual-Fee Gas Card

Earn rate: 5% cash back on your top eligible spend category each billing cycle (up to $500 in purchases), 1% on everything else.

This is the card to have if gas is consistently your biggest monthly spend. The 5% auto-applies — you don't choose a category, it just earns on wherever you spend the most. If you fill up two or three times a week, gas will often be your top category without you having to think about it.

The $500 monthly cap means you max out the 5% at $25/month ($300/year). For most drivers — even heavy commuters — that cap is plenty. The average person spends $175/month on gas; well within the cap.

Best for: Daily commuters who spend $200–500/month on gas and want a simple, no-fee setup.

Watch out for: If you have a month where you spend heavily on dining or groceries, those categories might edge gas out of the #1 spot, dropping your gas earn to 1%. Easy to track; just check your monthly spend.

2. Costco Anywhere Visa® by Citi — Best for Costco Members

Earn rate: 4% on eligible gas and EV charging (first $7,000/year, then 1%), 3% on restaurants and eligible travel, 2% on Costco purchases, 1% everywhere else.

If you already have a Costco membership ($65/year), this card has no additional annual fee and is one of the strongest everyday cards available. The 4% on gas is uncapped up to $7,000 in gas spend — at $175/month, that's well under the cap with room to spare.

The 3% on restaurants and travel stacks nicely. Running the numbers: $175/month gas × 4% = $84/year on gas alone. Add dining and travel and this card easily returns $200–300/year for a typical household.

Catch: Rewards pay out once a year as a Costco certificate, redeemable for cash or merchandise at Costco. If you don't shop there regularly, the payout mechanism is inconvenient.

Best for: Costco members who want strong gas earnings without paying a separate credit card fee.

3. Blue Cash Preferred® from American Express — Best for High Gas + Grocery Spenders

Earn rate: 3% on gas at U.S. gas stations (unlimited), 6% at U.S. supermarkets (up to $6,000/year), 3% on transit, 1% elsewhere.

The $95 annual fee is offset fast: $6,000 in grocery spend at 6% earns $360. Add gas at 3% and the math works out strongly for families or households that spend heavily on both.

The trade-off vs. the Costco card: gas earn rate is 3% vs. 4%. But if groceries are your #1 spend, the 6% grocery rate makes this the better overall card. The categories are also clean — no enrollment, no caps on gas, and the card is accepted broadly.

One note: The $95 fee is partially offset by a $84/year streaming credit (Disney Bundle), dropping the effective annual fee to ~$11.

Best for: Households spending $400+/month on groceries and $150+/month on gas.

4. PenFed Platinum Rewards Visa Signature — Best Credit Union Option

Earn rate: 5x points on gas (at the pump; not pay-inside or convenience store), 3x on groceries, 1x on everything else.

No annual fee, no cap on gas earnings. PenFed membership is open to anyone (you can qualify via a $17 contribution to a related organization). The 5x points translate to roughly 5% when redeemed for travel or gift cards, though cash redemption values can vary.

The catch: Points-based redemptions are slightly less flexible than straight cash back, and the 5x specifically requires paying at the pump — not inside the station.

Best for: High-mileage drivers who prefer credit union products and want uncapped 5x on gas.

5. Sam's Club® Mastercard — Best for Sam's Club Members

Earn rate: 5% on gas everywhere (up to 6,000 gallons/year), 3% on dining and takeout, 1% on Sam's Club purchases.

The 6,000 gallon cap is substantial — at 30 mpg and 15,000 miles driven/year, that's 500 gallons, well under the 6,000 limit. Even for a two-car household, most people won't hit the cap.

Sam's membership runs $50/year (or $110 for Plus), so factor that into your calculation. The card earns everywhere on gas — not just at Sam's pumps — which makes it genuinely flexible.

Best for: Sam's Club members or people whose nearest gas station is a Sam's Club warehouse location.

How to Choose the Right Gas Card

The answer depends on your full spending picture, not just gas:

If gas is your only focus: Citi Custom Cash (no fee, 5% up to $500/month) or PenFed Platinum (no fee, 5x uncapped but requires pump payment).

If you want gas + groceries covered: Blue Cash Preferred (3% gas, 6% groceries, $95 fee offset by streaming credit) or PenFed (5x gas, 3x groceries, no fee).

If you have a warehouse club membership: Costco Anywhere Visa (4% gas, no additional fee for Costco members) or Sam's Club Mastercard (5% everywhere on gas).

If you want one card for everything: The Costco Anywhere Visa covers gas, dining, and travel at strong rates and is a solid everyday card with no additional fee.

Common Gas Card Mistakes

Paying inside instead of at the pump. Several top gas cards — including PenFed — only earn the bonus rate when you pay at the pump. Paying inside the convenience store often codes as a general purchase.

Ignoring the category definition. Amex's Blue Cash Preferred earns 3% at "U.S. gas stations" — this excludes Costco gas (which codes as wholesale clubs), some warehouse clubs, and gas purchased at superstores like Walmart. If you fill up at Costco gas, you need the Costco Anywhere Visa to maximize earnings there.

Double-checking caps at year-end. Some cards reset caps annually (e.g., Costco resets its $7,000 gas cap January 1). If you're a high-mileage driver, timing large fill-ups around cap resets can squeeze out extra earnings.

Forgetting travel-day spending. When you're actually on a road trip or heading to the airport, your gas spend spikes. A dedicated gas card that you don't habitually use for other purchases is easy to pull out at the pump without thinking about it.

Combining Gas Cards with Travel Cards

The most optimized setup for travelers: pair a dedicated gas card with a flexible travel rewards card.

Use the Citi Custom Cash or PenFed for gas (5% back). Use a card like Chase Sapphire Preferred (3x dining, 2x travel, transferable Ultimate Rewards) for everything else. This two-card setup covers all major spend categories at strong rates without carrying five cards.

If you're planning an international road trip or using those travel card points for flights, you can use Faroway.ai to build a full itinerary that maximizes your points redemption — especially useful when routing award tickets or booking hotels with transferable points.

Bottom Line: The Best Gas Card in 2025

For most people, the Citi Custom Cash℠ wins on simplicity: 5% on your top spend category, no annual fee, no enrollment, no hoops. If gas is consistently your top monthly expense, it earns itself on autopilot.

For Costco or Sam's Club members, the co-branded warehouse cards are better because they earn more on gas and you're already paying the membership fee anyway.

For high grocery + gas spenders, the Blue Cash Preferred is the stronger total card even with the $95 fee — the 6% grocery earn rate is hard to beat.

Pick the one that fits your actual spending patterns, not the one with the best marketing. The best gas credit card is the one you'll actually use consistently — and that earns you more than the $21/year you're leaving on the pump right now.
