How far can you go?

[Jules-C]

Ok, so I did a little experiment...  basically I went for a ride.  218 miles later with a bit of bimbling and hooning.. the gauge has just dropped under the bottom line but the light has not come on... so I now know how far I can go.  :-)

The needle can go surprisingly far below the empty mark but the light should come on long before that.  Is the bulb still working?  Do the low oil and low petrol lights both light up when you press the started button?
