This article would allow me to start with the following, somewhat longer quote from an article on automotive fuels and lubricants, see :
In the advertising materials of the companies that make these ingredients, customers are promised to resume engine compression, performance, reduce oil consumption and extend the service life. These effects are to be achieved by "applying" the CSL alloy (copper, silver, lead) to the cracks and pores in the cylinder walls and thereby displacing the wills. Some more courageous companies have tried this process to be called a "general engine running" ... After reading the ad slogan, it is clear to anyone who understands the engines at least that it is nonsense. ... The authors probably had no idea what happened in the war.
The engine does not oil over the line
Do not be afraid, you are still on the Adaptogeny site and the goal of this article is to put some of the advertising claims about the biological "aditives" that offer our body what we naturally have in it . But when I chose this title, first of all about the oil (I copy from the contribution of the user P Jand from the discussion on garaz.autorevue.cz, see ):
Too much oil can be the same problem as too little. Most people live in "giving a little more and at least not having to go", but that is a big mistake. ... The upper line marks the level at which there is no overfilling of the crankcase. Repeat may have several unpleasant consequences.
The first is that the constant contact of the crankshaft with the oil causes it to "foam" in the crankcase, as well as loss of pressure, lubrication and damage to the key parts of the engine. The second problem is the increased lubrication of the crankshaft, connecting rod, etc. The engine is a relatively fragile system in which all the power and little damage and oil is not different. Excessive lubrication causes increased stress on the parts involved, and in this respect "contact with unexpected oil" is a problem. It is said that only the increased crankshaft cushion itself can be observed at reduced engine power. The third thing is that the pressure in the crankcase is too high. This again causes an increased stress on the engine components and sooner or later it results in leakage of the whole system and the oil leakage - seals, seals, etc. can not withstand the pressure in the long term.
The first (engine damage) ... really wants to flood a lot, but the other negative effects are to some extent inevitable from the minimum overflow - the upper line really is not for fun ...
Biosystems are more robust and effective in maintaining homeostasis, so there is no risk of "overflowing" with the addition of common metabolites , but we need money.
