Is it normal for a Audi to burn oil?

Audi, BMW, and Subaru stick firmly to the statement that oil consumption is a normal part of a car's operation. Subaru considers a quart burned every 1,000 to 1,200 miles to be acceptable. Certain Audi and BMW cars' standards state that a quart burned every 600 to 700 miles is reasonable.

Is it normal for a BMW to burn oil?

So, do BMWs burn oil? BMWs do burn oil more quickly than most other cars, but this is a normal part of the car's function according to the German manufacturer. BMWs can burn up to one quart every 750 miles, and even more if it's a high-performance model.
