I have found better fuel economy in Sport mode and I would agree with Mendo's logic on this.
As for fuel, my lease allows me to use either BP or Caltex. So far I've had a tank of BP Ultimate and a tank of Caltex Vortex and my economy has dropped on the Vortex.
I don't think I've been driving any differently so maybe it's all in my imagination.
I'll drive it to the Gold Coast tomorrow and see what I get.
