She had gone into the petrol station's convenience store when an employee alerted her that a man was entering her SUV.
She told local media she jumped into the back seat and told the man - later identified by police as 36-year-old Ricky Wright - to stop driving.
After he refused, she reached into the glove compartment to retrieve a handgun, and fired one shot at his face.
"I proceeded to jump in my backseat and told the gentleman to stop, to get out the car", she told KDFW-News. "He would not get out of the car."
"He turned around and looked at me. I reached over the arm rest to get to my glove compartment and that's when I fired at him."
She added: "I should have just emptied the whole clip but I didn't.
"I hope that woke him up."
Police say the man then crashed the car into a lamp pole. He was arrested and taken to hospital.
Police say the woman was questioned at the scene and released.
She is unlikely to face any charges, authorities add.
