Just wondering if someone could explain how the fuel display fluctuates so much.
Yesterday it said 43 miles remaining, today after driving on the motorway for a little while it has gone up to 62 miles remaining, without adding fuel ?
I can see that the gauge is dropping as the fuel is used but why such a fluctuation in miles remaining ?
It uses the last few miles you have been driving to calculate how far you can go if you continue the same way.
So coming from urban area out on the highway, your consumption goes down, and after a while it will start adjusting and increasing the distance left until empty.
And vice versa.
Is that the explanation you were looking for?
Thanks for that.
Mine fluctuates quite a bit.
They do, because consumption fluctuates quite a bit.
I don’t think you car is unique in that aspect.
