It really is an amazing and cheap treatment for bearing surfaces. The racing and motorsports industries have been using them for over 10 years to gain an edge in performance. I learned about them from researching how to increase the valve train rev limit from 6500 to 7500 on my 2013 Genesis Coupe 3.8 GDi turbo build project. With the OEM flat-tappet lifter design there was an inherent rotational limit due to friction heat as well as lifter slop at higher revs. I never finalized my head testing but based on the engineering specs; the Ferrea valve springs (40+ lbs each over stock), high-zinc synthetic oil and WPC treated cam surfaces I would be able to hit 7500 without issue even under 25psi boost. ?
