I am sorry your having this problem
is this something you plan on fixing yourself ?
or looking for a good idea before it goes into the shop ?
there is a service bulletin for this issue # *****: Engine Oil Consumption on Aluminum Block/Iron Block Engines with Active Fuel Management (AFM) (Install AFM Oil Deflector and Clean Carbon from Cylinder and/or Install Updated Valve Cover) - (Nov 26, 2014)
your car guy should have access to that bulletin number
the PCV valve cover needs to be changed and the oil pan needs to come off to remove the AFM valve and a new shield installed
all laid out in the bulletin on what to do and part numbers
if after the bulletin is done and it STILL uses this much oil then the piston rings would need to be changed
