Brother during city travel the average is over 14 if you drive normally with a light foot without accelerating or speeding aggressively.
If you push it hard and make jack rabbit starts, and drive very fast, it drops to around 13-13.5
On motorway i have made several trips but it has always been just two persons on board. If you drive under 120 it gives over 18km/l. But its very difficult to resist speeding on the motorway so i usuallly drive at 140 and then it does around 16.5km/l
