And separator effective enough to catch and trap the oil also collects and traps these damaging compounds as well, and you can never return these to the engine oil w/out severely accelerating wear. We sent off a sample of what is caught to Blackstone last week for analysis to share.
I could not reply to you via PM, but to answer your question I actually just sold my 2.0l ecoboost explorer so I have no current test vehicle.
