Although, that doesnt even address the question of whether or not our engines would even run with the everything disconnected after the EGR
Per the product description on IDparts.com it supposedly handles greasy deposits and residue. It also states recommended for preventative use.
IMO..I have yet to see any photos of carbon buildup which would fall outside preventative.
Hell, I'm at 49k moles so I may buy a bottle and try it out when I DIY my next oil change, DEF et al.
