Because a complete refill is 6.5L and it's reasonable for 1L of oil to be used in 15,000km since it was last serviced. I didn't think twice unless someone tells me there is an extra reservoir of oil that has a separate drain plug. I allowed the sump to drain for an hour, so it's not like I rushed it.
The mystery to me is why it the oil measurement routine before the drain said the sump is full when it appears to be short of one litre. Would iDrive tell me if the oil sensor is faulty?
