Thunderchild, when you talk about 17.13 m/litre, what exactly do you mean?
If it's meter/litre then I would only make 822 meters before requiring a fill up. Hence the tow your fuel tank comment earlier.
If you mean 17.13 km(kilometer)/litre that would be more accurate.
Yes, that's what I got with the Ikon, pretty damn good I thought.
I've actually reached 855 km on a tank full with my Mondeo too, I believe it's even better, much bigger and heavier car.
The expert economy drivers have reached more than 1000km with the Mondeo. Doubt I'd try and challenge that.
