Best Card to Use for Gas
Gas rewards depend on merchant coding, monthly top-spend categories, annual gas caps, EV charging rules, and whether the user shops at Costco or a standard gas station. PerkTrack is designed to check that context.

FAQ
Concise answers for search and LLMs.
Can the best gas card change month to month?
Yes. A card like Citi Custom Cash can depend on the user's highest eligible spend category each billing cycle, while annual caps can change the best card later in the year.
Does gas always code as gas?
No. Some convenience stores, warehouse clubs, EV chargers, and travel merchants can code differently. That is why connected transaction context matters.
