Best Amex card for gas

Updated September 24, 2026 · from RightCard's verified card and merchant data

American Express Blue Cash Everyday has the highest verified everyday gas value from American Express in our data: 3%. American Express Blue Cash Preferred ties it on value.

Amex's gas bonuses are mostly 3% cash on the Blue Cash cards. A few co-brand cards earn more points per dollar, but those points are worth less than a cent each, so the cash cards usually win.

Verified gas rates

Everyday rates only. No limited-time offers, no welcome bonuses. Ranked by value per dollar, not by the biggest multiplier.

Card	Gas	≈ value / $1
American Express Blue Cash Everyday	3%	3¢
American Express Blue Cash Preferred	3%	3¢
Hilton Honors American Express Card	5x points	2¢

Value column: cash at face value; points at conservative per-program estimates (Hilton Honors 0.4¢) toward travel. Cash out and most points are worth 1¢ or less. RightCard lets you flip between the two.

The part people miss

The bonus follows the store's merchant code, not the sign on the door. Superstores and warehouse clubs are the common trap for grocery. Hotel restaurants and stadium concessions are the usual traps for dining. When the code does not match, the purchase earns the base rate, and no app can change that.

How RightCard handles this: add your cards and the gas tile on Home shows the one card that wins, including this quarter's rotating bonus and your bank offers. The app is free and private. No bank login. Recommendations are computed on your phone.

FAQ

Which Amex card is best for gas?

American Express Blue Cash Everyday has the highest verified everyday gas value from American Express in our data: 3%. American Express Blue Cash Preferred ties it on value.

Does Hilton Honors 5x beat Blue Cash 3%?

Usually not. Hilton points are worth about half a cent each, so 5x is about 2.5% in value. RightCard values each program separately so this shows honestly.

Where these numbers come from: RightCard's data pipeline re-checks each card's published rates weekly and lists a rate only after two independent sources agree. Merchant codes come from our merchant directory. If a card or store is missing here, it is because we could not verify it, not because we guessed.
