If the 76 gas stations are the stations you visit most, we would recommend you to get a regular credit card with gas rewards. Such card will reward you for gas purchases you make everywhere, including at 76 locations. All other purchases will also earn rewards. Regular cards do not have gas spending limits you should meet to earn rewards. However, they may have caps on rewards you can earn in particular category within a set period of time.
