I've filled up Berta again and regardless that first awful ~500km I've managed to get even better FE than with previous tank.
40 liters on 1054km
3.8 L/100 km
61.96 mpg (US)
74.42 mpg (Imp)
Not bad! Not bad at all
Don't you think so? I'm still #8 but I'm getting closer to Helga...
I wish I could have more 60+ tanks...
