We've done the same sort of mileage many a time and have had to put around 20-30 euros of petrol/diesel in. The only thing that I can think of is that the car was filled to the brim when we picked it up but as we filled it to the brim I'm still surprised. Incidentally we have to drive around 30km after we refill the car, admittedly it is mostly on a motorway but when we got to the car rental we were charged an extra 0.01euro for the diesel that we'd used in that 30km...
Is this the most fuel efficient car on the road?
