I'm guilty of this weekly. I drive my car until the dummy light reads Low Fuel. Panic sets in after 20 miles as then I know I'm getting close to running out of gas. Do you know you're limit and how far you can go? I too love the Seinfeld episode where Kramer takes the car to the limit with a car salesman. I shared on the show this morning we can all relax. Tank On Empty to the rescue. For many years drivers around this great country have been submitting to this website information of vehicle travel once the Low Fuel indicator activates.
