Fuel distance till empty
Just filled my 1998 S8 fuel tank to the brim and the computer is saying 255 miles left till I run out, this can't be right surely?
90 litres = 255 miles = 13mpg!. :Confused: Is there a way to calibrate this or is something not right? I own a 1998 Jaguar XJR and a 2001 M3 also and they're nowhere as bad as this. |
Hi and welcome to the forum.
If it's like the D3 then you have to drive a bit so the computer can calculate the range based on your current consumption. If you're sat in city traffic then 13mpg sounds about correct. |
The PF D2 was the same, it's based on the last little while of driving, so if you hit a nice long stretch of road, it'll start to climb up.
|
It calculates that figure depending on your recent driving history: so that suggests that you've just been either:
1 - doing a lot of urban stop/start driving and/or 2 - hoofing it a bit (only you know which…;)). It should recalibrate if you then start to drive it on longer runs (e.g. motorways): my wife would typically find that she could drive it for more than a hundred miles before the "remaining range" figure started to fall…. Not the most sophisticated system, but ok once you get used to its logic. |
Like said before it depends on recent driving. I have got it showing 150 when flooring it and 500 doing steady 50mph on speed limited motorway roadworks. Under normal circumstances it is showing 300-320 miles on full tank for me.

Cheers everyone, I have only had the car a week and in that time the airbag light came on and it's run out of fuel with a quarter of a tank showing.

I put in 75 litres to fill it up, I take it since it has a 90L tank 15L is sitting in one of the sides unused?
|
I recognise that S8 - did it come from Swindon by any chance? +++
