I've had mine since September 2012, and l've got 33,000kms (20,500miles). I work out every tank of gas, and my life time average is about 18.5 US MPG. That includes every single mile that l have driven divided by the amount of fuel that l have used. So considering that in that number is city, stop and go, and highway driving, l'm very happy with that.
