Accuracy of Km/Miles till Empty readout?

Pulled into the servo last night, LCD Display reading 49Km (30miles) till empty.
Been doing city traffic driving all week. Gauge was sitting off empty at the 1/8 mark

Now according to all official documents, the ST has a 48L fuel tank... And I managed to fit 47.5L before the pump went 'click'. Methinks I wouldn't be able to do that last 49Km on just half a Liter of motion-lotion.

Anyone else found the Distance to Empty figures... optimistic?

In my experience, the "Miles to Empty" readout is less accurate than the needle for the gas gauge. The readout will vary from over-estimating to under-estimating the amount of fuel left, depending on whether it has seen highway or city driving.

You would think that Ford could make the system more accurate, considering how much is computerized on the car. I have personally driven 50 miles past zero in my 2011. I haven't tried that with the ST, and I think I trust reading the needle on the gas gauge more than the computer's estimate.

It's better to take the readout as a warning, rather than as hard number for the amount of fuel left. There's just too much uncertainty.
