Keep in mind the dash gauge is estimating your mileage based on ECU conditions such as throttle position, O2 readings, knock/timing, etc. It will never actually be close to what you'd get in real world conditions, unless what you drive on daily is exactly what the computer fuel consumption map is like programmed from the factory.

Hi alex I understand what you're saying , at first I did think it the ECU had a learning curve. I honestly don't know which are the values my ECU came adjusted from factory settings. But I did measure quarter tank from the beggining and what I do know for sure it's that I did only 36KM with the first quarter tank. The Fuel average at first showed 50Litres/100km CRAZY! after I enabled G-on it came down to 25/100km CRAZY again.
Maybe I should disconnect the battery and reset the ECU.
It could also be the fuel on the tank it's not RON98 .. bein a lower octane.
Honestly I'm out of ideas. what's your bestadvice?
