This:
I saw 3.8 liters on 100 kilometers a moment before, but then the petrol engine started again, probably to keep me warm, so it shows 3.9 here.
An hour after that I went to pick up Zuleikha and two of her class mates from school and had an average of 4.4 liters / 100km on that trip. With four people in the car, and part of the way going 100km/h on the country road.
Not too bad for a car, is it? Better even than my motorcycle which also takes around 4.5 liters on average…
