Cleaning the engine is normally one of the tasks of engine oil. All modern oils contain one or another additive package that gives them the ability to dissolve deposits in the engine and keep them in a suspended state (this property is called dispersing) until the moment of replacement.

If the car throughout its history used high-quality oils with high cleaning characteristics, oil changes were made in time, there were no overheating and any engine failures - then you can separately and not be bothered with additional cleaning of the engine with the help of "soft" or "fast" flushes. However, not every car can boast such a "clean" history. This means that the engine most likely contains deposits that the engine oil can not cope with on its own.

Presence of contamination in the engine can have various negative consequences:

• First, they quickly contaminate any new oil. This means that from the very beginning, the oil works a little worse than it could. In the future, it is destroyed faster, loses its functional properties, protects the engine worse, which reduces its resource and pushes repair.
• Second, contamination can interfere with individual mechanisms and nodes to cope with their work. For example, reducing the mobility of piston rings leads to a drop in compression, which means incomplete combustion of fuel. Fuel consumption increases, the dynamics of the car gets hooked, and new deposits are formed. The accompanying breakthroughs of exhaust gases in the crankcase, the ingress of unburned fuel into the oil, again degrades its characteristics, can accelerate the failure of the turbocharger and other units.
• Thus, the accumulated contamination in the engine causes a kind of" chain reaction " leading to a deterioration of the entire engine and an increase in the probability of failure.

Below are a few typical cases and symptoms in which it makes sense to seriously think about using a special engine wash ATOMIUM APROHIM™.

ENGINE OVERHEATING, OIL "ROLLING", USE OF LOW-QUALITY FUEL OR ENGINE OIL.

All the above cases lead to the same consequence - the formation of contamination. It is not so important that they appeared as a result of destruction (destruction) of engine oil due to overheating, because the oil has overworked its term and could not cope with cleaning, or for other reasons. It is important that the contamination appeared, which means, as described above, will start the process of forming new ones. If something of the above has happened in the history of the car, it makes sense to apply engine flushing before the next oil change (and do not delay it for a long time). This will allow you to deal with the initial contamination at an early stage, when it is quite easy to do so.

MECHANICAL FAILURE

In any case, almost any mechanical failure in the engine leads to increased contamination. For example, if a piston ring is cracked, it almost automatically means that for some time the exhaust gases were able to get into the oil, interact with it and form a Deposit on the internal surfaces of the engine. The same consequences are caused by "crushing" and cracking of oil-removing caps, and so on. In many cases, you can restore the problem with a fairly simple repair. However, until the problem was detected, the engine was running in an abnormal mode, which means that contamination has already formed. After such accidents, it is recommended to replace the oil with a new one as soon as possible, after using additional flushing.

SWITCHING FROM ONE TYPE OF ENGINE OIL TO ANOTHER

As mentioned above, the new oil has stronger cleaning properties, simply because the cleaning additives have not been worked out yet. Because of this, it actively washes away the contamination that the old oil could not cope with, which means it is more likely to fail. This is especially important to consider if there is a transition from a lower-quality oil to a higher-quality one. For example, from mineral oils to PAO-based (Polyalphaolefins) oils that have even higher washing and dispersing characteristics. In order to preserve the working properties of the new oil for longer and allow it to better protect the engine from friction, it makes sense to use the engine wash before replacing it to remove contamination as much as possible along with draining the old oil.

BUYING A USED CAR

When buying a used car on the secondary market, you can never be completely sure that its history is "clear". Even if you have a service book that shows timely maintenance AND oil change, it is never possible to know for sure - whether the engine overheated, whether the car worked in difficult conditions of prolonged standing in traffic, whether there were minor breakdowns. What this threatens the engine is described above. That is why when buying a used car, it is recommended to replace technical fluids and lubricants as soon as possible, especially engine oil. And before replacing it - clean the engine by flushing. This will help protect you from unpleasant surprises and unexpected repairs, which are unlikely to cost in the budget plan.
