Best credit card for gas (2026)
Blue Cash Preferred offers 3% cash back at U.S. gas stations. Some rotating-category cards hit 5% in bonus quarters but only part of the year. A flat 2% card is the reliable fallback when no gas bonus applies.

Why most people pick the wrong card
Most people default to the same card at checkout — usually the one on top in their wallet. That habit quietly costs hundreds of dollars a year when another card in your stack earns 3×, 4×, or even 6× on the same purchase.
How Pikt routes smarter than guesswork
Pikt links the cards you already carry, weighs your offers and category earn rates, and tells you the best card to use — with a plain-English explanation and dollar estimate for every purchase. Online, the Pikt Checkout extension auto-fills that card at checkout; in-store, Pikt Nearby names it on your lock screen. Warehouse clubs and grocery-store gas pumps sometimes code differently than branded stations — Pikt accounts for that.
