Yes, indeed. Besides, the other thing that has changed is that now I'm doing fillups every time (800 km) as opposed to before where I did only partial fillups for up to 5000 km. So now, I'm seeing more the impact of daily weather and traffic conditions.
I had a terrible 3,3 l lately, I think I abused of the heating ventilation, 110W
.
That is one of my worst FE except the one at constant 110 km/h (3,68 l).
I can already see that my current fillup looks good after 400 km (I know exactly how my tank gauge reacts).
