Well, I don't know how far I went on my car. But I believe we have made 400-500 miles more than once.
And in the UK version of Top Gear, Jeremy Clarkson, Richard Hammond and James May went from Basel, Switzerland, to Blackpool, UK, without stopping for gas. Without the Channel Tunnel, they did 780 miles. And it seemed that Clarkson's car ran out of gas, but it actually had for another 120 miles, so it would have peaked at 900 miles without filling up!
