 We've had the car a year, now, and have put over 15,000 miles on it. We use it mostly around town, so rarely gas it up. I filled the tank in November. As I write this, I still have half a tank at the end of May.My wife has macular degeneration, so the extra driving help all the sensors provide are very useful. We can drive it across state touching only the steering wheel and turn signal on the interstate.
