So this morning (10 degrees outside, mild), I switched the car on and sit for 2 minutes waiting for my wife.
In that time with A/C off and the temperature at 21c I managed to drop my MPG from 33.5 down to 32.6
(The car only had about 10 miles tops since I reset last night)
Does everyone get this kind of drop sitting doing nothing in their civic ?
I've never had good MPG from it even when my cautious and clever driving wife was at the helm most of the time, best I've ever had was 36 mpg after a 3 hour drive to the Lake District.

I am amazed the drop was as low as that - according to my calculations, to drop from 33.5 MPG to 32.6 MPG after 10 miles would use 0.04 litre. Therefore while sitting it is using 1 litre of fuel an hour.
