Driving modes

What mode do you 200 turbo drivers use on a day to day basis to drive around in? Would you be able to drive in sport mode all the time or does this really affect your mpg? Or is there enough in the acceleration to leave it in normal mode?
 
there is enough acceleration in normal, but i also tend to drive in sport as not much more fuel useage if any

in normal i tend to drive in auto, in sport i will use the paddles
