fuel

[PaulSmith]

5 ltrs allows for me being stupid and not noticing Im on empty. And as it makes no real difference, as in its not a reserve better to give myself a bit more time.
Also planning to ride in France and Spain next year. I have done a lot of driving over there and when off the main roads it can be hard finding a petrol station.

Fair points. Probably wouldn't work to well for me though as if the fuel light doesn't mean "think about getting fuel now!" then I would start to ignore it.
