I've travelled about 1700kms now on mine. Last time i poured i drove about 409kms with about 5 litres left in the tank, and that's with me driving like a granny and because its all city driving i don't expect fuel economy to be so great. I do remember flooring the car 3 times though.
I'd say about 400-450kms on a tank. so 11-12.5L/100km
