Mercedes uses Mobil 1 from the beginning on the AMG powered cars, so why wait to change the oil. These newer cars have short "wear-in" periods. Very low piston ring drag & roller rocker arms. Also all engines are run at the factory for at least 5min. Plus I'm sure that the technician doing the new car prep work will help by flogging it.
