How to add other info to main page of mobile app?

This is what our app looks like:

For each row I would like to add the amenities for the particular gas station (ie. "parking", "bathroom", etc). For example, "Rocket Fuel" has parking, bathroom, and a mechanic.

How can I add this information to the list without disrupting the main purpose of the app (display gas prices)?

People use the app because it tells them the gas prices, but I would like to give them more information without altering the existing flow of the app, or its primary purpose.

My biggest concern is that the list will be too crowded, or maybe adding the information will somehow affect what the users think about the app.

As a sidenote, an app like Gasbuddy (which is similar to our app but doesn't compete with us) also displays this additional information with icons, but when a user clicks on a gas station. For some reason, gasbuddy decided not to add the icons to the main page.
