The best fuel-rewards credit card for a frequent driver depends on where you fill up and whether you will use the rewards—not just the biggest percentage in an ad. For U.S. drivers who already belong to Costco or Sam’s Club, those clubs’ cards advertise 5% rewards on qualifying fuel purchases, subject to different caps and redemption rules. If you want a no-annual-fee card without a warehouse-club tie, Blue Cash Everyday is a useful comparison: NerdWallet reports 3% back at U.S. gas stations, up to a $6,000 annual category limit.
These are not interchangeable offers, and none is automatically best for everyone. Compare your usual stations, expected eligible spending, membership costs you would not otherwise pay, and how easily you can use each reward. The terms below are based on U.S. information current to November 2026; confirm the issuer’s live terms before applying.

Which fuel-rewards card should a frequent driver choose?
Choose based on your regular fuel stops and the reward you can actually redeem. Costco’s card is the most compelling of these examples for an existing Costco member who buys its gas; Sam’s Club’s card can fit an active member who uses Sam’s Cash; Blue Cash Everyday is the simpler club-free comparison if its eligible categories fit your spending.
Start with where you normally fill up. If a warehouse-club pump is not on your route, a special rate there may be irrelevant. Next, estimate your annual spending at eligible fuel merchants, not just your total fuel budget. A transaction at a grocery store, superstore, or warehouse retailer may not count as a gas-station purchase under the card’s terms. Finally, ask whether you will use the rewards in the form offered: a percentage is only a headline rate until the issuer’s category rules, cap, and redemption conditions are applied.

For a frequent driver, the difference between a card’s bonus rate and its ordinary rate can narrow once the eligible-spend cap is reached. The relevant question is therefore not simply “Which card has the highest gas percentage?” It is “How much of my actual spending will qualify for the bonus, and what will I receive for it?”

How do the three cards’ fuel rewards work?
The three options differ in rate, cap, qualifying merchants, and reward currency. Costco and Sam’s Club advertise 5% rates in defined circumstances, but both require a club relationship and their rewards are not identical to unrestricted, immediately available cash.
Costco Anywhere Visa Card by Citi
Citi’s current terms list 5% cash back on Costco gas and 4% on other eligible gas and EV charging purchases, up to a combined $7,000 in annual spend; after that threshold, the rate is 1%. The card also lists 3% on restaurants and eligible travel, 2% at Costco and Costco.com, and 1% elsewhere. Citi says there is no annual card fee with a paid Costco membership. The reward does not replace the cost of membership: if you would join Costco only to get the card, account for the membership expense in your comparison.
Citi says the enhanced fuel rewards began January 19, 2025. It distributes card rewards annually after the February statement closes, according to its Costco reward certificate FAQs. That timing matters if you expect a quick statement credit. Do not treat the advertised percentage as an immediate pump discount or assume a certificate is unrestricted cash; read the current certificate terms to see how and when it can be redeemed.
The $7,000 ceiling is shared between Costco gas and other eligible gas and EV charging, rather than being a separate $7,000 allowance for each. Once qualifying purchases pass the threshold, the listed rate falls to 1%. Because Citi describes the threshold as annual, check the current card terms for the period and calculation details rather than assuming the cap resets on a particular date.

Sam’s Club’s published program terms list 5% Sam’s Cash on the first $6,000 of eligible gas-station and EV-charging purchases in each calendar year, followed by 1%. The cap is a combined limit for those categories. The account holder must maintain an active Sam’s Club membership, and purchases qualify according to merchant category code. That code is assigned to the merchant or transaction; the label on a pump or the fact that you bought fuel does not by itself guarantee the bonus.
Also popular on Amazon
Sam’s Cash is not the same thing as unrestricted cash back. The program’s terms tie it to Sam’s Club redemption rules, and state that rewards are generally issued within one to two billing cycles. The terms also describe an overall annual Sam’s Cash ceiling. Check the current version of the program rules for the applicable ceiling, redemption options, and any other restrictions before treating the reward as equivalent to a bank deposit or statement credit.
The published program terms are older than the October 2026 comparison roundup, so verify that the terms remain current. In particular, confirm the cap, eligible transactions, and redemption rules before applying or relying on a specific rate.
Blue Cash Everyday from American Express
NerdWallet’s October 2026 roundup reports 3% at U.S. gas stations, supermarkets, and U.S. online retail, with each category capped at $6,000 in annual spending and 1% after the cap. NerdWallet describes the card as having no annual fee. Its gas rate is lower than the club cards’ advertised top rates, but it does not require a warehouse-club membership. The grocery and online-retail categories may also matter if you want one card for several household expenses rather than a card chosen mainly for fuel.
These details are reported by NerdWallet; confirm the live issuer terms before applying. Category definitions and caps matter even when a card has multiple bonus categories: a $6,000 gas-category allowance is not automatically a $6,000 allowance for every category combined, and the issuer’s rules determine how spending is counted.
How much are the advertised rewards worth before the cap?
A percentage can be translated into a simple estimate by multiplying eligible spending by the reward rate. At the stated rates, spending $1,000 on qualifying fuel would produce $50 at a 5% rate, $40 at 4%, or $30 at 3%, before accounting for caps, membership costs, redemption restrictions, and any transaction that fails to qualify.
At the full bonus thresholds, the arithmetic illustrates why the caps matter. If every dollar qualified at 5%, $7,000 of Costco card fuel spending would correspond to $350 at the bonus rate; after the combined cap, additional eligible spending earns 1%. For Sam’s Club, $6,000 at 5% corresponds to $300 in Sam’s Cash before later eligible spending earns 1%. Blue Cash Everyday’s $6,000 gas-category limit at 3% corresponds to $180 at that rate, then 1% on eligible gas spending beyond the cap. These are calculations from the listed rates and thresholds, not forecasts of a driver’s reward: eligibility, category coding, reward terms, and actual spending can change the result.
For example, suppose a driver spends $500 a month on fuel, or $6,000 in a year. If all of that spending qualified, the nominal reward would be $300 at 5%, $240 at 4%, or $180 at 3%. But that comparison does not account for whether the driver buys gas at the relevant club, pays for a membership, earns Sam’s Cash rather than cash back, or can use a reward certificate when it arrives. Those conditions can matter more than the difference in headline percentages.

For a driver spending more than a card’s bonus cap, calculate the return in two parts: spending up to the cap at the bonus rate, then eligible spending above it at the stated base rate. Do not multiply all annual fuel spending by the highest advertised percentage. Also avoid assigning a dollar value to points or club rewards as if they were cash unless the current redemption rules support that value.
Will a gas purchase at a grocery store or warehouse club qualify?
Not necessarily. The issuer’s eligible-category rules and the merchant category code used for the transaction determine whether a purchase earns the gas bonus; a fuel pump located at a grocery store, superstore, or warehouse club may be classified differently from a conventional gas station.
That caveat can change which card is best. Costco’s own gas rate is specifically listed separately from the rate for other eligible gas and EV charging. Sam’s Club’s rules rely on category codes for qualifying gas-station purchases. For other cards, do not assume that every purchase involving fuel gets the same treatment as a standalone gas station. A station inside a larger retailer, a convenience store, marina fuel, or another nonstandard merchant can be an edge case.
Before choosing a card around one particular pump, read the issuer’s rewards terms for eligible merchants and exclusions. If the terms are unclear, ask the issuer how that merchant type is treated. Keep in mind that a response about a merchant category may not guarantee how every individual transaction will post; receipts and statements can help you identify the category or reward actually credited.

Convert the fixed discount into a percentage at the local price per gallon, then compare it with the card’s eligible reward rate. A cents-off offer is worth a larger percentage when fuel is cheap and a smaller percentage when fuel costs more.
The calculation is: cents saved per gallon ÷ pump price per gallon. For a purely illustrative example, a 5-cent discount at $3.00 per gallon equals about 1.67% of the fuel price; at $5.00 per gallon it equals 1%. This does not mean a loyalty offer is always better or worse than a card. A card reward is tied to the purchase amount and may have caps or eligibility rules, while a cents-off offer may have its own station, purchase, or redemption conditions.
Also popular on Amazon
Kiplinger reported that cited chain loyalty programs offered about 3 to 10 cents per gallon in savings, but that is a reported range, not a guaranteed current offer for every location. Check the local program’s current terms. NerdWallet’s Sara Rathner also recommends combining a gas card with fuel loyalty programs and checking prices along a route with tools such as GasBuddy or Google Maps. The practical comparison is the total price after usable discounts and rewards, not the biggest advertised number in isolation.
Stacking can be useful, but verify the rules before counting both savings. A loyalty discount may change the amount charged to the card; the card’s issuer then calculates rewards on the eligible transaction as processed. Do not assume a discount and a card bonus both apply to the original, undiscounted pump price.
What should you check before applying?
Use a short checklist to compare the card with your real driving and spending patterns, then confirm that the issuer’s current offer matches the terms described here.
- List your usual fuel stops. Separate Costco, Sam’s Club, ordinary gas stations, and fuel bought at grocery or superstore pumps. Note any stations where you routinely fill up, rather than picking a card based on a location you rarely visit.
- Estimate eligible annual spending. Use the amount you expect to spend at merchants that should qualify under the issuer’s terms. Compare it with the $7,000 combined Costco threshold, the $6,000 Sam’s Club calendar-year threshold, or the $6,000 Blue Cash Everyday gas-category limit.
- Account for membership costs you would newly incur. The Costco card has no annual card fee with a paid Costco membership, but that does not make the membership itself free. Sam’s Club requires active membership. If you already pay for a club membership for other reasons, do not count its entire price as a new card cost; if you would join only for fuel rewards, include the cost in your math.
- Identify the reward you will receive. Costco distributes rewards annually after the February statement closes; Sam’s Club rewards are Sam’s Cash subject to club rules; the Blue Cash Everyday information describes cash back. Confirm current timing and redemption conditions, especially if you need flexible cash or a fast credit.
- Check all categories you would use. A card with a lower gas rate may still make sense if its other useful categories fit your spending. Citi lists restaurants and eligible travel among its bonus categories; NerdWallet reports supermarket and U.S. online-retail rewards for Blue Cash Everyday. Compare only categories you would otherwise spend in.
- Read the current terms before applying. Reward rates, caps, fees, application offers, and eligibility rules can change. Confirm the issuer’s pricing and rewards documents, and do not rely on an older comparison page or a headline offer alone.
What are the trade-offs for frequent drivers?
The Costco card’s strongest case is straightforward: an existing Costco member who regularly buys Costco gas can access the listed 5% rate, and qualifying fuel elsewhere or EV charging has a listed 4% rate until the combined cap. Its trade-offs are the membership requirement, the shared cap, the 1% rate after the threshold, and annual reward-certificate timing.
Sam’s Club’s card has a similarly prominent 5% headline rate, but the reward is Sam’s Cash, the qualifying transactions depend on merchant coding, the cap is $6,000 per calendar year, and active membership is required. A driver should not treat its reward as fungible with cash back unless the current redemption rules make it so for that driver.
Blue Cash Everyday offers a lower reported gas rate, but it avoids a warehouse-club membership requirement and includes other reported bonus categories. That can be useful for someone whose driving routine is spread across ordinary U.S. gas stations or whose broader spending makes a single household card more convenient. It still has a category cap, and the precise eligible merchants and current terms should be checked with the issuer.

Other cards appear in NerdWallet’s October 2026 roundup, including Bank of America Customized Cash Rewards, Chase Freedom Flex, Discover it Cash Back, Wells Fargo Autograph, Blue Cash Preferred, PenFed Platinum Rewards, and U.S. Bank Altitude Connect. NerdWallet describes some as broader-category or points options, including Wells Fargo Autograph as a multi-category 3X option and PenFed Platinum Rewards as earning 5 points per dollar at the pump without a gas-spend cap. Those descriptions do not establish the current cash value of points, all eligibility conditions, or their fit for every driver, so they are not ranked above the three cards with clearer terms here. A reader considering them should compare current issuer terms and redemption values rather than assume a point rate equals a cash-back percentage.
How were these cards selected?
This comparison focuses on U.S. cards with fuel rewards and uses the rates, caps, and conditions stated in current issuer terms or NerdWallet’s October 2026 roundup. The three examples cover distinct choices: a Costco-focused card, a Sam’s Club membership card, and a no-annual-fee general-market option. Priority went to clearly stated fuel rates and caps, practical membership and redemption caveats, and differences that can change a frequent driver’s actual return. The roundup’s other cards are noted as alternatives, but they are not ranked without enough confirmed current detail to compare their costs and redemption value on the same basis.
All card reward information can change. Review the issuer’s current terms before applying; the issuer terms and NerdWallet’s October 2026 roundup provide a November 2026 snapshot, not a promise that future offers or transactions will be identical.
Frequently Asked Questions
Do fuel rewards apply to electric-vehicle charging?
The Costco card’s listed 4% category includes other eligible gas and EV charging, and Sam’s Club’s terms include eligible EV-charging purchases in its capped category. The merchant and transaction still need to meet the issuer’s eligibility rules.

Usually, the rate describes rewards earned on an eligible purchase, not an instant reduction in the posted pump price. Reward timing and redemption rules differ by card, so check whether the benefit arrives as cash back, a certificate, or club rewards.
Can I use a gas-rewards card for business fuel expenses?
The information here covers consumer card reward terms and does not establish business-use eligibility, tax treatment, or expense-reporting rules. Check the card agreement and consult a qualified tax professional about business deductions.
Will fuel bought at a convenience store earn the gas bonus?
It depends on how the merchant transaction is classified and on the card’s terms. A convenience store that sells fuel may not necessarily code the purchase as an eligible gas-station transaction.
