IIRC, the trip computer works out the range according to your average mpg over the last ten miles - I think that's showing as 40-ish mpg, though, which seems high.

I'd be minded to fill it with juice til the pump clicks off, then work off say, 25mpg... IIRC, it's a 12 gallon tank (or thereabouts). I've heard stories of people running out when the range says 40 miles, so it's not too accurate...

HTH.
