I do not see any issues with oil consumption in my car, but after 111K miles it must have some carbon accumulation on the rings and the intake valves. So I hope to clean the rings and the combustion chamber. Also, based on the info given in the videos, there may be a residual cleaning action from the exhaust recirculation system carrying the blow by gases mixed with the oil over the intake valves. But this is not something they measured or advertised. They only advertised the rings and combustion chamber.
Direct injection does not clean valves, so short of walnut blast or other invasive methods that require opening the engine block, this may be the safest way to try to ensure the intake valves are clean. If they are still clean, it will not hurt.
However, it supposed to take about 2-4 oil changes for the rings to clean up. So this is not a detergent flush type of process, but a regular oil (with mild detergent qualities) used during normal operation.

Agreed, Lake is definitely knowledgeable and gives off vibes that he's a a corporate shill yet, but as with the way the world is, any time a YouTube video slightly gives off infomercial vibes, I assume it's a paid advertisement for the product, and it usually is.
