Been away so late to the Party....
Let me put it this way .... If you alter the design, operation or intended use on a vehicle still under warranty FCA will use that as the club to beat you with and deny you warranty for any engine related issue. Hell if you can not produce proof you did oil changes regularily they will deny any warranty. We use that engine in everything and I don't recall ever running into a dry oiling failure that wasn't related to improper maintenence or poor quality/wrong viscosity oil. Yes the upper valve train is prone to taking a while to produce suffucient oil pressure as the Hemi guys are aware and are using the Hellcat Oil Pump to counteract that but for the 3.6L you are at the mercy of the oil gods. Once the factory warranty has run out anything goes.
Over the years, it seems that many consumers are not aware of the extensive R&D activities the OEMs put products through BEFORE they hit the showrooms. I know, as well as they might test things, there will always be some customers who can tear up an anvil in a sandpile. Which is one reason Chrysler used their in-house relations with Dollar and Thrifty Car Rental to place early-production models at their larger airport rental stations. Accumulate lots of miles quickly in different environments.
Then, they put their factory sales, parts, and service reps in their products, to generate in-house data on those vehicles, too, before the vehicle "went to the dealer auctions". In the LH years, they'd even use their regional tech-instrtuction center operatives to test some refinements in products (as brake pads) as a part of the evaluation period.
Granted, where the OEMs set their "benchmarks of performance" can vary, BUT you can bet that if they are chasing a law enforcement customer, THEY want to ensure that customer has no issues with their vehicles! IF anything happens that is durability-related, it gets addressed and fixed to maintain that customer. Ford and GM do this, as the pre-Stellantis Chrysler also did this. As these things filter down to the retail customers, it makes for a better total vehicle for them too.
AND, IF that oiling issue really is a durability issue related to the engine's design, it IS ALSO possible that the engineers upgraded certain parts to better tolerate the situation! End result, no issues until the 3rd owner might get the vehicle after 300K miles, at which time the engine would need to be rebuilt anyway, or is in the salvage yard, where it would be sold as "a core" only.
I am not against private inventors devising ways to make things better, but it sometimes seems that they play into the possible fears of people in order to sell their products. NOT saying that that is the case with this product, just an observation I've seen over the years with many other products. Some people used them with no adverse issues, for example, as others did not know of them and had no adverse issues either.
