RP just has EP additives in their oils, worthless for an engine, but it makes them look good when people do testing like that. Slick 50 and various other snake oils did the same testing on TV ads back in the day.

Royal Purple has been in my offraod Turbo charged 22re with sustained 250+ temps at 15+psi(4+hrs no cool down) with no loss of a bearing or major engine failure.
The Bearing's look great upon teardown and the piston where able to be reused. Say what you want but that stuff coats the engine. I've seen it with my own eyes.
