How to get free gas:
It is highly unlikely that you will ever find truly free gas, but there are several ways to save money on gas.
There are lots of credit cards out there that will give you certain percentages of the money you spend on gas back to you as rewards for putting the gas you buy on your credit cards. IF you do a little research you can find a card that works really well for you. Some cards work only at certain gas stations, but there are others that work at all stations. Also, some cards are better if you are planning on carrying a balance, and others are better if you plan to pay them off every month.
You can sign up for programs online that will send you gas cards to use to get free gas in return for filling out surveys and giving your opinions on certain things. The high cost of gas makes giving up some of your free time a little more enticing. Some of the gas cards have a pretty high value for a simple survey.
