Only happened to me once. I was coming back from Kansas city to Colorado Springs on I-70. I planned on getting gas at about 1/4th, but I kept pulling in to closed gas stations. Then the gas light came on, I didn't know how far a gas station would be that was actually open so I was doing 25-30mph on the highway. Finally I came to Ft. Riley of all places to get gas. By this time I had done 45 miles with the gas light on. I would not recommend trying this at all for reasons already mentioned in previous posts.
