I get to drive against the traffic to work, so for the longest time I get 13.6 l/100km. On average I would get about 450km per tank. The worst would have been for 1 week where I had to drive in traffic with 16+ l/100km and ended up 350km for that tank.
Most of my trips to work is on normal mode, and most of my trips leaving work is on M mode.
Looking at all your figures, I feel like I ain't using the car as properly as I should...
