One of the things I might suggest you do is to get yourself a bluetooth OBD2 adapter and Android app called 'Torque'. This will let you see information in real time , and also read OBD2 diagnostic codes.
You haven't mentioned any check engine lights, so there may not be any codes to read. However , I know from recent experience with a similar problem, that you can actually get codes that are 'pending' and don't actually set the check engine light. Not to mention being able to see real time data from your car's ECU can be a big help in understanding what's really going on.
My 2012 Cruze recently started running really bad , but unlike yours I'm not burning any oil and not smelling any oil, nor is the idle dipping.
My issue is major loss of power and gas millage , later to realize that I have a intermittent loud ticking noise coming from under my valve cover. My noise is so loud that it is triggering the car's knock sensor system , which is causing a major retardation of timing... and mine is throwing these 'fault pending' codes P0324, and occasionally a P0325. I've seen the codes with my Torque app on multiple times where they are listed as 'fault pending', and only a few times to the point where they actually triggered the check engine light and a more permanent fault code ( again P0324 and/or P0325 ).
Many people report ticking noises, usually they are written off as coming from the fuel injectors and/or the purge valve in the fuel line. There seems to be almost no information out there on the internet about ticking noises that can be attributed to other things besides the injectors. If you should find any , let me know cause I am interested in learning more about what other Cruze owners have found out about loud ticking that isn't attributed to fuel injectors and related components.
Back to your troubles... Given all the talk of oil smell and/or consumption, you may very well have issues that go way beyond even what I personally am having. I think you should be concerned about it... I'm sorry I can't be of more help with your specific issue at this time, but I am personally curious about what you ultimately find with your situation.
Good news for you is that your car is still under warranty, mine is not... mine with just over 108,000 miles, also with regular oil changes of Mobil 1 ( Dextos approved )
