How long till the fuel status will stable?

[xsender]

So i just got the car and im driveing for 3 days now.
On the first day that I took the car I refueled full tank.
Every body how understand in cars mechanics told me that the engine need to be "opend".
My fuel economy that I have got by now not so good.
So when I should really check it again?

Welcome!!!!!! So how new is the car? And how many miles are on the car? If it's Brand new you have to slowly get the car broke in. Meaning during that period you take it easy on the car. And ck the oil from time to time. And drive it Easyer for a while. And your gas mileage should get better and better. If not have the Dealer check it out for you

So the fuel will be better and better from refuel to refuel?

[debburyl]

How much driving are you doing? You have on the dash a botton you push that shows how far you drove and counts the miles you've went

[xsender]

I did 150km .

What fuel economy do you have by now? Although I don´t think it is possible to evaluate the fuel consumption after only 150 km.

Fuel economy of my Space Star only got better a little bit after 5000 km, I would assume about 5 % compared to the first two fills and not considering my different driving style. But it is necessary to know the car to get a good fuel economy and to adapt to the car, too. Altogehter I improved from 3,7 l/100 km to 3,4 l/100 km.

What motor do you have, the 1.0 or the 1.2 liter engine?

I have got 1.0 manual .
and i know that it will be better after of couple refuels . Im just asking when
coz my fuel economy shows me 4.7 litres per 100 km .
to get to 5000km it will take me a lot more then 2-3 refuels .

4.7 l/100 km is a real good fuel economy figure. 4.9 l/100 km is the average for the Space Star 1.0 at spritmonitor and if you are a rather normal driver (driving 100 kph if possible, not changing to 5th gear at 50 km/h, not driving only long distances) this fuel consumption is a very good figure you should get used to, perhaps you will reach 4.5 l/100 km over time.

You won´t find a gasoline car that has a better fuel economy in real world driving.

[xsender]

yeah but it strange .
how much kilometres i need to have at the end of the tank?
35 litres the whole tank

If the car is showing 4.7, you are probably actually getting closer to 4.8 or 4.9. (Most owners find the fuel consumption computer is a little bit optimisic.)

So you could go roughly 700 km if you used up all 35 L.

The fuel gauge will start flashing, warning you to fill up before you use all 35 L, of course.
