True I always follow the shake and fill method which I assumed was inaccurate VS cutoff

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 ).

I still cant figure why the obsession with accurate FE, approximate FE is fine if you ask me. Apart from the above post, I for one believe that filling to the brim is a bad idea, since it confuses the safety system in your car, am talking about the spill valve and over flow can which also gets filled.

The better way to get minimal air lock is to have the tank filled slowly, than at full flow. Try this and see you will get consistent FE readings. Alternate option is to use the bottle technique where fuel is fed from a separate can, this is tedious since it involved disconnecting fuel lines and all.

Full tank is 38 litres if i remember correct.

I don't worry about measuring FE. I just put the odometer reading in a google spreadsheet, along with cost and liters.
So I now have the exact FE computed over 20,000kms along with cost/km.
