You have what’s known as a loose motor, some say it will last longer then a tight motor. I don’t know about that, but what others have said is right the manufacturer not the dealership sets the rules on oil burning, because they have to pay to fix it. You still have lots of warranty left, so keep an eye on it and if it gets worse make sure the dealership knows. Also document the oil loss with the dealership starting now so you have proof this is a long term issue.
