Having this liquid in your gas tank can cost you and your car in the long run. 

A Rockford gas station got the surprise of their life when a consumer contacted WREX TV last week. The woman said she stopped for gas and later in the evening, her car started to run different.

The next day, her car died and she took it to the dealership. The mechanics told her she had water in her gas tank. Up to 70% of her tank was nothing but water.

The gas station where she purchased the gas did take care of her expenses and also apologized.

Here are one way you know if your car has water in the gas line, according to Bell Performance.
