There are several things...
- the instant consumption
can say up to 200 mpg but that doesn't really give you an accurate average consumption.
- on the road I average about 32-24 mpg a tank (but this combines driving in and out of the city everyday and also the obligatory thrash now and again)
- on journeys I can get up to about 45 -48 mpg but more realistically i'll say 40-43 mpg.
I do drive like a granny though
