Together with all of the above, small metal shavings are attached to the engine block, which appear from the rubbing parts of the unit itself. Naturally, not all of these harmful particles are deposited on the power device of the car, much of them linger in the filter or completely dissolved in oil. But even in such circumstances, the engine becomes clogged, the mass of deposits of dirt and waste of working parts increases, increasing by the time the end of the life of the previously filled oil comes.

Why do I need to clean the engine?

Some car owners believe that the motor is the most powerful component of any car that does not need additional maintenance, in particular, in periodic washing with special solutions.

The car owner himself must choose one way or another, who can proceed from the circumstances that have contributed to the need to carry out this procedure.

Methods that promote major engine flushing

To date, every motorist can resort to one of the three known methods of washing the power unit. As practice has shown, all of the following methods do not harm the engine and at the same time require only minimal costs. In order to flush the engine, you will need regular oil, special flushing agent or a five-minute solution.

Since each of the methods has its own advantages and peculiarities, before proceeding with the implementation of the conceived, the process of each washing method should be considered in detail.

The first method, which requires the motorist to use conventional oil, is to be able to clean the power unit with simple engine oil, which in its composition has various kinds of cleaning additives. The substance used in everyday life to lubricate moving parts will help flush the engine. To thus free up the power unit from the accumulated carbon deposits, you should pour the engine oil in the car and drive it only 3 thousand km. In addition, the car owner will have two times during the run to change the filter unit. Immediately, as soon as the old oil will be removed, and the old filter will replace the new device, the owner of the car can not change these consumables in the car as much as the manufacturer needs. However, master professionals recommend using this method only when the engine is slightly littered or the car owner wants to clean the engine for the purpose of prevention.

Oil must be replaced

The second method involves the use of special flushing oil, which can be purchased at any auto shop. It is advisable to use it when replacing the engine oil. Discounts for new cars! Profitable loan from 9.9% installments 0% From a simple oil, this type of substance is distinguished by the presence of a significantly larger number of various cleaning additives. If the car owner purchased the flushing oil, flushing can be done immediately after the waste oil is drained. As a result of this manipulation, it is necessary to start a car and let it work for at least half an hour. It is worth considering that not all engines will be cleaned with the same speed, this indicator is influenced by the brand of purchased flushing oil. As a result, after the procedure, the engine becomes much cleaner, flushing oil is removed from it, and in its place a suitable motor substance is poured to lubricate the components. At the same time it is best to change the filter device. Most often, the engine can be cleaned with flushing oil with average pollution or a planned change in the type of oil used.

A five-minute solution does not have a specific composition, this phrase refers to virtually all existing additives that motorists add directly to the engine oil before its planned replacement. To use this method of washing the power unit, you need to add to the crankcase acquired in the automobile shop any additive. With the additive poured in, the engine should work for at least 10–20 minutes. It should be noted that for each substance this time period is not a single standard, it is best to familiarize yourself with the instructions in advance and do everything according to the described recommendations. It must be remembered that overexposing the cleaning solution in the engine is not recommended - this may adversely affect the device being washed. Most often, those additives that are part of any "five-minute", have aggressive properties that can adversely affect the glands.

Experts recommend resorting to the acquisition of special additives only if the engine is very dirty. Due to the presence in the "five-minute" of strong chemically active substances, the car owner can damage the gaskets and seals, all non-metallic elements of the engine can be at risk. Choosing this method of cleaning the power unit, it should be remembered that it will not completely drain the used oil out of the engine, this rule applies to additives - some of the solution will get into the new engine oil, thereby deteriorating its properties.
