I would go a little farther to say that its not just useless its harmful to the car/truck/motor. Notice when ppl store their vehichles over the winter they put stabalizers in their fuel tank and oil resivour. Thats so that the gas doesnt break down. If you try and use old gas it will cause serious damage. I dont really konw exactly how long but i wouldnt let gas sit in my gas tank longer than 30 days.
