I’ve had this credit card for well over a year now and it is by far the best rewards card for gas that I have in my wallet.  This card earns a whopping 5% cash back that is automatically applied to your account as statement credit; no need to buy gift cards or anything. In order to avoid the annual fee and earn the full 5% cash back, you need another PenFed “qualifying” account. I just set up a savings account in which I automatically deposit $35 a week so that it covers my monthly gas expenditures.
