It is good to know that there is a reserve, I have had some cars that when the light came on it only had half a gallon left. (2005 Buick Rendezvous) I have been driving a Jeep Wrangler with a 22 gallon tank. It was a "brick on wheels" when it came to gas mileage, but I could go could feel safe going for over 350 miles on a tank. It is taking some getting used to having only 13 gallon tank, but a lot easier on the wallet.
