I've been keeping track of my consumption since I bought the car new (102.000km)
- best fuel 6.96l/100km
- worst fuel 11.43l/100km
- avg fuel 9.07l/100km (220 refuels). Using "intelligent" gearbox mode, with manufacturer recommended tire pressure.
I-mode and recommended tire pressure:
- best 7,1l/100km (<- summer)
- worst 9,4l/100km (<- winter)
- avg 8,8l/100km (<- per year)
These are calculated by myself. Car computer will show approx 0,5l lower consumption.
If i may ask whats your climate, we got 10C outside atm.
I have noticed that below 10°C it could take 10-15km (80km/h) before water/oil temperature is raised to normal level. Don't know could this affect to fuel consumption and if then how much.
That's why I'm using mask cover (or what it is in english) when temperature is +5°C or below:
At least water/oil temperature will rise to normal bit faster. And of cource when possible I use block heater.
