Yes, this EA888 engine and the similar 2.0-litre EA888 can have an oil consumption problem. The trouble is, in your case, it is not yet sufficiently severe to force the supplier to do something about it. However, you should write to the supplier expressing your concern, send your letter by Post Office Special Delivery, keep a copy and staple the certificate of posting to the copy so it becomes a matter of record that you did bring this to the dealer's attention at an early stage.
