It's normal. Turbo cars burn a little bit more oil than naturally aspirated. Also, it consumes a little bit more in the break in period. Depending on your driving habits, the milage you will get that error varies. I've read about people here who see that warning in 5-6k miles.
The low engine oil warning kicks when you are 1 qt less that the regular level. So nothing to worry about. If you go to the dealer they just top your oil off and let you go
