With High Fuel Prices, Is a Gas Credit Card Worth It?

For the most generous gas discounts, look to rewards credit cards that pay 5 percent cash-back savings on gas purchases, Rossman says. 

You can find options with no annual fees. Just make sure you understand the limitations on the discounts. 

The Citi Custom Cash Card, for example, gives cardholders 5 percent cash back on their top spending category each billing cycle, which can include gas, for up to $500 in purchases per cycle. Other purchases earn 1 percent cash back. 

For those who find it worthwhile to purchase a warehouse club membership, Sam’s Club and Costco offer credit cards that pay generous cash back on gas purchases, which can be made at any gas station. 

Sam’s Club MasterCard pays 5 percent cash back up to a $6,000 annual cap, then 1 percent thereafter. The Costco Anywhere Visa Card by Citi pays 4 percent back on gas purchases up to $7,000 per year, then drops to 1 percent.

If you drive a lot and expect to bump up against a rewards cap, consider using that card just for gas purchases, while opting for another for different spending categories, Rossman says.

Another option is the PenFed Platinum Rewards Visa Signature Card, which pays five-times points on gas purchases and electric vehicle charging stations, with no mileage cap. Those points can be used for travel, merchandise, and gift cards, among other categories.

The card is available through the PenFed Credit Union, which is open to new members with a $5 deposit. To earn the highest gas rewards, however, you need to qualify as an Honors Advantage member, which requires you to be in the military or open a checking account with PenFed.

While rewards cards may offer better discounts, for those who lack good or excellent credit, you may find it easier to qualify for a gas card, because you can often qualify with a fair credit score, says Bill Hardekopf, senior analyst at Moneycrashers.com.

Most gas cards don’t charge annual fees, but you’re likely to be charged steep interest rates if you run up a balance. Shell, for one, levies a 29.49 percent APR vs. the 18.79 percent national average for credit cards.

As noted earlier, gas card discounts are modest. Say you buy 35 gallons of regular gas a month, paying $3.92 a gallon, for a total of $137.20. Assuming your card gives you a 5-cent reward rate, you’d get back $1.75, which works out to a cash-back rate of 1.28 percent. 

You may also bump up against caps on the number of gallons that qualify for the discount. And your discounts are typically limited to the gas company’s brand.

Still, some cards offer other benefits, such as discounts on nonfuel purchases or cash back in other spending categories. 

Among the top choices, Hardekopf points to the BP Credit Card, which takes 5 cents off every gallon at participating BP and Amoco stations and gives a 1 percent discount on nonfuel purchases at those locations. Another version, the BP Visa Credit Card, takes 10 cents off each gallon and gives a 3 percent discount on groceries and 1 percent on other purchases. 

Some gas retailers also offer discounts if you’re signed up with their programs and use a mobile payment app, such as Apple Pay or Google Pay. 

To max out your discounts, try to combine them with other rewards programs whenever possible. 

Many gas brands have their own apps that offer a few cents off per gallon on a purchase, and they don’t require a gas-branded credit card. Instead, you can use your rewards credit card to pay those charges.

“By linking a credit card that pays gas rewards, you can stack both discounts,” says Rossman, who uses this strategy himself.

For example, you might use a Sam’s Club Mastercard paying 5 percent cash back on gas with the Phillips 66 app recently paying 10 cents off per gallon. 

When it comes to fighting inflation at the pump or anywhere else, every little bit helps.
