In brake-in service the engine oil and differential oil will be changed and as far as I have heard the different type of oil will be used... even if this is not truth, still those oils must be changed with new oils to prevent future damage to engine/differential or oil consumption... If I were you, I would not drive the car more than 1500 miles before brake-in service...and don't listen to CA or other staff in dealership since they really don't care about cars... their job is to sell and maintain cars... that's it
