Where can you Buy “Gas” with a Chase Freedom or Discover It Credit Card?
Warning, this is an untested experiment, so YMMV. Proceed at your own risk.
I’m sure most of you already know that the Chase Freedom and the Discover It credit cards offer 5x or 5% cash back at gas stations this quarter (July 1 – September 30). But do you know what Chase and Discover consider “gas stations”? Let me explain…

Credit card companies use Merchant Category Codes (MCC for short) to determine which merchant or merchant category you are shopping at. For example, Office Supply Stores are one MCC, Marriott is another, and Gas Stations are another. You can learn more about the MCC search tool here. For this post, I will just share what I did and point you in the right direction.
To start my search, I searched for my local gas station chains (ARCO, Chevron, and Shell) near my zip code.
