Do I need to clean the engine when replacing the oil?

Do I need to clean the engine when changing the oil? At many forums, it is possible to find heated discussions of this issue. Supporters of both points of view are confident in their rightness to one hundred percent, giving all sorts of arguments. But what about the usual car owner who wants to just decide the question, is it necessary to wash the engine before changing the oil or not? For example, in the dealer centers are sure that it can not be done in any case.

To wash or not to wash and what for it to do?

Unequivocal answer the car owner, unfortunately,can not find. The fact is that there are many factors that influence this process. In the car dealerships you can find such washes, which promise to clean the engine in a matter of minutes. But it is better to avoid such methods.

In general, flushing in some cases may benecessary, but not in others. For example, if the history of the maintenance of the machine is clean and all the necessary replacements are made in a timely manner, then there is no need to flush the engine.

But it happens when it is desirable or even necessary:

• if the viscosity of the oil during the change is changed to less, for example, from synthetics to mineral water;
• also you can even have no doubt whether you need to clean the engine before replacing the oil with another brand - the answer is obvious;
• Of course, after a motor repair, replacement is also needed;
• if the unit is clogged, for example, a liquid of antifreeze or fuel has got there.

Harm from washing

If the car was bought in the showroom, hethe procedure for flushing the motor is not required. Also if the motorist always used only high-quality oil, you can not even think about whether you need to flush the engine when changing the oil. The fact is that the composition of modern mixtures include various additives, which are designed just for cleaning the motor. Therefore, all contaminants are washed off with the used composition.

Moreover, if you still wash itunit, it can even be harmed, since it is known that up to ten percent of the mixture usually remains in the pan. But with the application of the quick miracle washing mentioned above, the creators of which promise a magical result in a few minutes, it mixes with the used oil remaining in the engine and the latter qualitatively changes its structure. This is especially true of the viscosity characteristics.

As a result, this mixture remains in the engine, andpouring fresh deteriorates and its quality. It will not be noticeable immediately, so the car owner can then not even compare the breakdown with the engine washing. But, unfortunately, this can happen.

Therefore, it should be borne in mind that in some cases, in addition to the useless waste of money, time can also worsen the state of the "heart" of your car.

When flushing may be required

But there are situations when the question is, do you needrinse the engine when replacing the oil, there is no doubt. So, if a car is bought not a new one, but a used one (of course, there can be cases of buying from good acquaintances and relatives whose use of cars you know for sure), then washing will not be superfluous. However, in this case it is worth to think about how to produce it. After all, an incorrect or frivolous approach can ruin a motor.

Disassembly of motor

So, you can flush the engine several timesways. The mechanical part of the unit is dismantled and hand washed all parts with kerosene, gasoline or solar oil. This is the best way when all the engine elements are visible. But it will take a lot of time and it will not be worth it. In addition, not all motorists will want their motor dismantled.

15-minute

The famous so-called"Fifteen minutes", which is simply poured into the unit and turned on for this time. Then the entire spent mixture is drained. However, if you need to flush the engine when replacing the oil in this way, most car owners raise justifiable doubts.

Two-day

Another way that is no longerpopular, is in the same washing as in the previous way, only it lasts not fifteen minutes, but one or two days. The washing oil is poured into the car, and the car owner drives it for a while, then comes to replace it. The method is inconvenient, since the driver has to limit himself while driving and spend a lot of time visiting a car dealership.

Dangers of 15-minute

Previously, the method of "double-day" used was, as already described, extremely inconvenient. This inspired the manufacturers for the very fifteen minutes, which today are filled with auto shops.

Conducted many tests provedeffectiveness of the method. The engine was really cleared! So what's the point and what's the catch? The question is whether to clean the engine before changing the oil, can be removed once and for all!

But, unfortunately, not everything is so unambiguous. What is the result of such intensive purification? The fact is that active detergents have a very high concentration. Therefore, the process of destroying the oil seals accompanies the excellent cleaning of the contaminated oil. Manufacturers have foreseen this, and in the composition of 15 minutes, a chemical additive was added, which, when in contact with rubber, creates a protective protective layer from the alkaline effect. At the same time, to the metal deposits, as the developers claim, the tool is categorical. And this is a proven fact.

But, unfortunately, there is a more unpleasant moment. Operation with a low-quality oil often leads to the formation of large deposits on the pallet. They themselves do not carry any danger. However, fifteen minutes can play with this bad joke. To process a large number of deposits at once is beyond their power. As a result, what was accumulated on the bottom remains in the engine in a dissolved form with rinsing residues, which are then mixed with the new oil. It remains only with bitterness to imagine what will happen to the engine, when such contaminated oil will work out its resource. Unfortunately, there have been cases when, after three washes with fifteen minutes, the engine of the machine, which was previously operated on cheap raw materials, came into disrepair and was no longer subject to repair.

Now you can take a fresh look at the question whether you need to clean the engine when changing the oil.

If your situation is close to that, then rinseIt is necessary to manually clean the engine by completely cleaning the pan. This approach will be correct and safe for the motor. If, because of the high cost or for any other reason, this is not possible, that is, another good way to flush the power unit. And it does not consist in the chemical method, but in the use of ordinary high-quality oil.

Washing with conventional oil

If the question is whether to flush the enginebefore replacing the oil, the opinion of experts converge and the answer is positive, then you can use the following method. The motor is turned on and heated to a certain temperature. Then they muffle, drain the oil, fill a new high-quality and change the oil filter. The next two or four days to go is necessary in run-in mode, so as not to let the unit be overloaded.

After that, the procedure is repeated and twice more is used for the newly filled oil than for the normal mode.

If you come to the conclusion that the motor flushingit is necessary, then seriously approach the question of what can be flushed before replacing the oil, so as not to spoil it in the end. Agreeing to high-speed facilities, do not forget about the pitfalls that can expect your car in the future.
