I follow the cut off mode always. the following are the advantages over the shake and fill method -

1. During shake and fill most of the time the Fuel overflows due to careless pump attendants (>50% of the time this happens).
2. Fuel expands when temprature increases. If you fill the Fuel in the morning, fill it to the brim using shake and fill method and then use the car only for a few KMs to work there are chances of overflow of Fuel from the tank due to expansion. This I haven't experienced myself but have heard people say.
3. During Shake and fill one tends to loose fuel or change (Invariably our petrol pump folks will not have 1-2 rs. change ).
