Anyone know the capacity of the screenwash bottle - It would be useful to know so I can mix my screenwash to the right consistency - Also, any tips on figuring when it's full / empty?!
Shame it's not economic to fit a level indicator to the bottle - mind you, if the accuracy of my fuel guage is anything to go by

Why not fill an empty 2 ltr Evian bottle with the right concentration and use this to fill up the washer bottle on the MINI? That way you guarantee the correct proportions and also can ensure it is fully mixed.
