I used to get ~380 miles from about 54 litres in my 1.6 petrol Focus Manual. Mostly stop start journeys to work in Central London on nights, less stop start on the way home in the mornings.
Tonight I did my first journey to work in the 1.8 petrol Octavia Auto, got 32.4 on the way in according to the maxidot, will be interesting to see how that changes on the way home in the morning. Journey in took 1:15 to cover about 20 miles.
