It's not 'oil consumption' as typically thought of, IMO. On an old or very high mileage engine, oil can be burned in the combustion chambers due to excessive clearance (wear) between the piston rings and cylinder walls. I think that is really unlikely to be the cause in these new engines, but, it is easy to check for so why not do a cylinder leakdown test. From the various unfortunate owner's stories I don't recall it being mentioned. These sure aren't iron 360's or 440's but the principle is the same.
On the Multiairs, if oil isn't visibly leaking out but large amounts of oil are disappearing, well, where does it go? Seems likely it get's pulled out of the crankcase as an oil mist or aerosol by the PCV system, which in turn feeds into the engine intake and is burned off in the engine or cat. Another simple test therefore would be to observe the tailpipe during a cold start - blue-ish smoke indicating oil.
Oil spray/oil mist systems are common nowadays in industrial rotating equipment, which I have some experience in
However they are vulnerable to oil contamination. It doesn't take much to negatively affect the nozzles. Typically the major source of contamination is when oil is changed or topped up, and avoiding that requires strict attention to cleanliness and avoiding ingress of unfiltered air. Example as you take oil out of a barrel outside air is being drawn in, so the barrel itself needs an intake filter. Another problem is incorrect oil, for example while transferring oil from barrel to crankcase you must use a clean container, no residue from other oil left in the container. In my experience with local FCA dealers they have trouble doing a proper oil change in any case, so I ****ING HIGHLY DOUBT they follow correct oil handling procedures. And if you as the owner are dutifully pulling the dipstick and checking the level, you too are likely contaminating the oil.
Long story short my guess is that the some nozzles are off spec from the start, or get contaminated at the factory or during oil changes. Resulting in poor spray patterns causing more oil mist or aerosols than normal, causing oil to 'disappear' out the tailpipe.
