"Balanced additive formulation".
No doubt there is a VOA somewhere on this oil and I'm sure it has a healthy additive package. Probably has roller cam followers although all you could see in the video were roller rockers. Not to take anything away from the oil, but this engine rarely gets cold started I'm guessing in a commercial marine environment and probably lives most of its life at stable operating temps. This is a huge difference from running errands in a diesel pickup truck or even normal civilian driving in a diesel pickup.
Marine environments are also dust and dirt free by nature. Shouldn't make a difference with proper air filtering, but in the real world, some dirt always seems to get past the filter in, say, a construction or mining environment vs a marine installation. Great teardown, though and it was totally unnecessary on this engine other than to have a "peek" inside.
