So, do you know how much gas is left in the tank when the low fuel light turns on? For those of us with older cars, we have to kind of guess how much longer we can drive before the car just stops from lack of gas. For those lucky people with a car that tells you how much you have left when the gas light comes on, you still might find this post interesting, especially if you are a passenger in an older-style car. If you're like me, when the gas light turns on, you tend to panic a little bit. However, now thanks to DefensiveDriving.com, you can panic a little less the next time the gas light turns on.
