When should the engine be flushed when changing the oil?

Experienced car owners often hear recommendations to perform regulatory engine flushing, using a special auto chemical for this purpose. However, masters, who are engaged in repair of power units, still recommend carrying out such work only in strictly defined situations. Let’s talk in detail about whether it is necessary to flush the engine, performing engine oil replacement and how such work is properly performed.

Where does the contamination come from?
In the process of car exploitation the oil properties start to deteriorate, so called corking occurs, when sediments are formed inside the engine, clogging the channels and considerably worsening the lubrication of hard-to-reach places in the engine. The appearance of such a solid deposit is a natural process, which is simply impossible to prevent. It is possible to partially solve such a problem by frequent oil changes, which considerably alleviates such caking, preventing the need to perform overhauls.

Just to remove such deposits which have appeared inside the engine, its flushing is performed. With the use of special flushing compositions all dense deposits are washed out, which significantly improves the condition of the engine, providing its subsequent proper lubrication, including hard-to-reach places in the engine. For such washing and pollution removal both special active compositions and detergent oil may be used, which is poured into the engine and the car is operated during several hundreds of kilometers, then the oil is changed together with all impurities.

Features of flushing fluids
Regardless of whether special fluids are used to flush the engine or it is an oil that contains numerous detergent additives, such chemistry is an aggressive composition, which negatively affects the condition of numerous rubberized gaskets in the engine. It is believed that a special oil is more gentle on the impurities inside the engine, while removing them and not degrading the condition of the rubberized gaskets in the engine.

The car owner when performing such engine flushing should act in accordance with the instructions for each specific product. If a special liquid is used, then the engine is given to work only a strictly defined time, after which it is drained with all the impurities. With engine oil, which has improved detergency properties, you usually need to drive a few hundred kilometers, and then drain it, filling it with new, fresh, properly selected oil.

Pros and cons of flushing
With such a flushing, you can remove all the existing contaminants inside the engine, which appeared as a result of prolonged use of not too good quality oil. This improves engine performance, preventing engine coking and critical malfunctions. However, such flushing can also be detrimental to the engine. Not only is there a chance of damaging the oil passages, which get clogged by dense, large pieces of dirt, but also of damaging the rubberized gaskets, which often need to be replaced after such a procedure.

Not surprisingly, many professionals who repair and service engines recommend using quality oil and changing it regularly, which eliminates the need to perform such an engine wash. More often than not, such engine flushing is required when the type of oil is changed or the car was purchased from hand and it is unknown what kind of oil was used before. In all other cases, you should still refrain from washing the engine.

To sum up
Engine flushing has both advantages and disadvantages, which should be taken into account when carrying out such a procedure. Washing the engine from the inside is recommended only when the car was bought with hands and it is unknown what kind of oil was used earlier and how often it was changed. In all other cases, washing the engine can only cause significant damage to the engine, forcing the car to be overhauled soon.
