Made it to 800 - wanted to get an image dead on but nowhere to stop for .8 miles...
Managed another 10 or so miles and filled up. Getting closer to 50 MPG US which for mostly town driving in stop-start isn't bad.
Going to go for another 800 before the weather turns for winter - it already has here in North Britain as anyone interested in Golf will know. Might not get an 800 tank as I'm on hols in a couple of weeks time and that isn't enough time to get to 800 in my normal commute.
