I agree that this should not have happened. I should have paid closer attention to it, but it was at the end of a long trip and we had filled up fairly recently and had been expecting to be able to make it home without an issue based on our average mpg and time spent between fill ups. I normally get 200 miles to the tank. I don't think this tank lasted more than 100-120 miles. It was a bit windier towards the end of the trip, but I've never seen it drop that fast. Lesson learned. The last thing I wanted to do was add 2.5 hours to my trip by running out of gas 2 miles from my final exit and gas station.
