does anyone know how the 'miles left till empty gauge works on our tintop, its a 2006 fiesta , not a real problem as such, when i left work it said 200 miles till empty traveled 28 miles home at a steady 60mph mostly on m-way got home and she says 182 till empty,
doe the car just guess at the miles left using a preset mpg , and i happened to do more mpg than the car thought

it uses the average mpg based on the last say 10 miles travelled.

yep, average mpg and fuel level in the tank

All the calculations are based on your AVERAGE MPG, if you haven't reset the mpg for a while it will be giving you a figure based on all the miles you have done since you last reset it.

thanks for the advice, but it means that i drive far more efficently than the wife
