2011 Calais V Series II high oil consumption
I'm not aware that Holden has said there is a fault with the engine that causes the high oil consumption; the reaction from dealers is usually the one you got, i.e., to monitor it.

2011 Series II Commodore Calais rattle noise
It could well be a valve lifter that's draining while the car is standing and the engine not running. It might be a case of establishing which lifter is at fault and replacing it, but you need an experienced mechanic to listen to it to determine where it is coming from. If it only happens when the engine is started from cold it might be necessary to leave the car with the dealer overnight.
