What oil purifier is better for the engine. Washing engine when replacing the oil: when to do how to rinse the engine

Disputes about whether it is necessary or not to rinse the oil system of the engine during the procedure for changing the engine oil, do not subside. The idea of \u200b\u200bthe need for washing there is both supporters and opponents, and not only in the car owners, but also among professionals. Let's not list the arguments and parties. The test of the "Avtodel" magazine, conducted jointly with the specialists of Liqui Moly, washed from the walls of the engine 180 grams of oil sediments, which already makes it possible to optimally look at the need for the procedure itself.

Also on the need to rinse the engine during oil replacement indicate other studies. In winter, 2012-2013 in the Moscow region there was a large number (about 400) of the engines in the form of the impossibility of their launch in the frost. Moreover, the "epidemic" touched quite new cars that are still on warranty repairs. To sin all steel on the quality of engine oil and began to exhibit claims manufacturers of engine oils. Shell conducted research and found out that paraffin deposits in the engine were made of hydrocarbons that were not kept in the outcome composition of the oil. This made it possible to assume that the cause of deposits was fuel. This fact caused a large discussion in the professional community. This fact allows you to look at the question of the need for washing the oil system during the procedure for replacing the oil in the engine.

So if you feel about the skeptics that believe that it is not necessary to fluff in the oil during the replacement of oil, you can not read further. We did the experiment, convinced the need for such a procedure. The case remained for small: you need to get a wash of the oil system of the engine and use it. That's just a question - what?

The search on the site of one of the auto shops found 160 items of washing the oil system, the price of which ranged from 55 to 745 rubles. The difference is 13 times, so the choice between cheap or expensive products is. To understand what is actually poured into a bottle with a beautiful label, we tried to compare the productive features of the product and its chemical composition, whose assessment was made in the Laboratory of MIC GSM and published in a blog of one of the LJ users. Take the work to explain what is written in the laboratory protocols and how it relates to what the manufacturer itself declares about the product.

Why do you know?

Before you take any tablet or medicine, a reasonable person goes to the doctor and clarifies what kind of medicine it. In extreme cases, in each package of tablets is a liner describing the chemical composition of the drug and the mechanism of its action. In the automotive store no one bothers to write the chemical composition of the additive or cleaner in the instructions. Everyone is limited to the laudatory words that the buyer acquires superserving, which makes the engine perfectly clean. But the cleaning mechanism, composition and possible complications with incorrect use no one is going to explain.

What could be in the bank?

Options for which cleansing additives are made, three.

The first option is "five minutes."

This additives are based on an organic solvent, its task is to wash off accumulated deposits. As a rule, many "five minutes" consist precisely from the solvent. Achilles fifth of such compositions is dissolution together with the deposits of oil film from rubbing steam. That is why they can be used only when the engine works at idle. If you load it at the moment when a solvent is introduced into the oil, there may be jackets on the unwashed items.

The second option is soft flushing.

These are flushing, which are added to the oil for 100-300 km to the replacement procedure. Their composition includes washing-dispersing additives based on calcium sulfonates.

The third option is symbiosis.

Accordingly, the "compote" can be made of washing of various types, adding solvent and washing-dispersing formulations to the contamination additives.

Thus, knowing what is contained in the oil system washing the tool, you can draw conclusions about the efficiency and safety of its application.

Probably, everyone heard about the old Dedovsky engine cleaning method: add solvent to oil. Acetone is a good tool, everything cleans. But only the time of this procedure needs to be counted with the stopwatch, so as not to reap and turn the engine. Therefore, the use of washing based on solvents (though not acetone) is very limited in time. That's just a question: what sediments will they wash off in 5 minutes of use? The answer suggests itself: only superficial. And God forbid during the procedure to gazalize - you can kill the engine ...

Manufacturers are looking for more complex compounds to wash off, and the engine does not damage. Liqui Moly is available as the most interesting in the composition of the five-minute flushing agent. In addition to the solvent, the manufacturer adds an anti-infamous additive based on phosphorus and zinc (it reduces the likelihood of damaging the engine during the procedure), plus there is also a washing-dispersing additive based on calcium sulfonate. This package of additives will not only complement the actions of the solvent and compensates for the shortcomings, but also minimizes the poisoning of fresh oil by the remnants of the spent.

Similar tools are most safe and effective, but, unfortunately, the rinsing composition for the engine is not written on the packaging, and find out what is worn there, you can only after laboratory tests. Our readers, based on the knowledge gained from the article on the chemical composition of one or another flushing, will be able to choose for their car a decent drug.

CONCLUSIONS

The diagram presented explicitly shows from which a means for flushing the oil system of the engine.

But evaluation of their effectiveness is not such a simple task. Let's deal with.

Let's start with the biggest "stick" with the adaptive washing of the engine Resurs.. In it, we observe the greatest concentration of the anti-wear additive, but it is not entirely clear why the manufacturer did not add a detergent-dispersing package? At the same time, the manufacturer itself declares that the solvents in the composition are not used. Due to which then the agent achieves a special cleansing effect remains a mystery. Yes, and the large concentration of phosphorus can negatively affect the operation of the catalyst.

Necession flushing Comma Petrol Engine.. Unusual flushing, which, according to the manufacturer's application, can be used as a five minutes and as a long-term washing of the engine. From which it can be concluded that the organic solvents are not used in it, and the effect is achieved by applying the drum dose of detergent-dispersing additives. The use of such a package in long-term mode is dangerous in contaminated engines, as the oil system may not cope with exhausting sediments and score.

Next goes LIQUI MOLY OIL-SCHLAMM-SPULUNG - The manufacturer it is declared as a flushing of long-term action, which is confirmed by laboratory studies. In it, the washing and anti-wear package does not greatly exceed the concentration of new oil and adding it to the engine for 100-200 km really can lead to a good result with minimal risks.

In the compositions LIQUI MOLY ENGINE FLUSH and LIQUI MOLY PRO-LINE MOTOR SPULUNG Detergent and antisaded additives are also present, but with an emphasis in the direction of the engine protection during washing. This is explained by the fact that an organic solvent was introduced. As a result, we have a balanced composition with a solvent, a protective and detergent component.

Preparations Hi-Gear Motor Flush HG2214, ER Professional Motor Flush P023RU, Hi-Gear Motor Flush HG2204 and El Trans Cleaner Oil System The test showed the presence of only washing-dispersing additive. Such a composition is difficult to call balanced. The manufacturer is clearly not concerned about the protection of engine parts during the washing procedure.

In the compositions in which neither detergents nor the anti-mailing additives consist of one solvent. Their use can lead to increased wear of the engine in friction pairs due to the dissolution of the oil film to detergent the engine.

Comments Technical Specialist of the company Liqui Moly, Dmitry Rudakova

"The main part of any additive for the washing of the engine is a solvent. The task of the solvent is to skitting the engine oil for better circulation and penetration into thin gaps. Also, the solvent removes some part of the deposits in the engine. Most manufacturers believe that this is enough, forgetting that the washing must be both effective and safe. The effectiveness of alone solvents is not enough to fully remove deposits, so famous auto-chemical producers add a clean-dispersing complex of additives that is used in modern motor oils. This complex or manufacturer "saved" can be defined on the basis of laboratory analysis, which was done in this test. The presence in washing alkaline and alkaline earth metals (pr .: sodium or calcium) unambiguously indicates additional detergent additives and displays the studied product in the category of highly efficient.

ABOUT SECURITY: It is clear that the solvent as part of the washing dilutes the oil, this leads to the thinning of the oil film and the risk of damage to modern high-known engines (scope and grabs). Responsible manufacturers solve this problem with the addition of antisaded additives, again the slowdest complex used in standard packages of additives of modern engine oils. The same laboratory analysis, on the increased content of zinc and phosphorus, makes it possible to conclude that antisaded components are added and washing safe.

It is clear that the cheapers consisting of a pure solvent are the most cheapers. The full range of clean-dispersing and antisaded additives lends the product, but gives the consumer confidence in the safety of the engine washing procedure, and sometimes without flushing the oil system and can not do. "

As a postscriptum

We added this paragraph for those who believe that the engine is not needed, but still read the entry. Most recently, the magazine "Driving" conducted a demonstrative test in which he estimated such an effect as the poisoning of fresh oil remains of the old after the replacement procedure.

The engine test showed that the use of the engine washing tools allows not only to reduce deposits in the engine, but also reduce the change in the physicochemical parameters of fresh engine oil due to mixing with a non-insulating engine through the engine.

Signed peculiarities

On the Hi-Gear Motor Flush HG2204 flushing manufacturer's web page not only describes whether the washing consists, and there is also a leakage on the topic, why it is necessary: \u200b\u200b"It has been established by specialists that the use of even high-quality oils does not prevent the formation of harmful carbon deposits On the inner surfaces of the engine and in the channels of the lubrication system. When the oil is replaced without the use of flushing, most of the contaminants remain in the engine. This is especially characteristic of engines with a large mileage, where the operation of detergent additives of fresh oil occurs significantly faster due to the existing strong contaminants. As a result, an active formation of oxidation and wear products occurs, which clog oil channels, are deposited on the inner surfaces, which reduces the heat sink, worsens the lubricant of the parts, causes the piston rings. All this leads to an increase in the wear of parts, reducing the power and deterioration of the fuel engineering engine.

It is stated that the highly efficient formula used in the washing of Hi-Gear HG2204 is designed specifically for engines with high mileage having strong contaminants, and allows you to remove most of them, including the engine crankcase. This contributes to the preservation of the working properties of the oil for a longer time and the extension of the engine life as a whole. The use of this washing when changing the oil removes most of the contaminants, oil decomposition products and carbon sediments (including engine crankcase pallet). Due to the use of this additive fresh oil and a new oil filter work more efficiently. The oil retains its properties longer, which leads to the extension of the engine life as a whole.

Thus, this flushing contains a powerful anti-wear package and the question immediately arises, and where is the detergent components? Why did the manufacturer not add to the recipe for washing-dispersing additives, whose task is to wash the engine and remove all the sludge out of it? At the same time, their presence is declared in the composition, but not in fact. In addition, experts immediately wondered, and what will happen to the catalyst when phosphorus get into it in concentrations on a lot more than the requirements of European standards. For this drug, the test revealed more questions than answers.

The package concentration is almost twice as high as motor oil. Underwater stones are in the other and open with attentive reading instructions. It turns out that the same means can be applied both as a standard five-minute and as a long-term additive. There is a reasonable question as a manufacturer managed to combine the effectiveness of cleaning with a quick flushing in the service and the possibility of long-term engine work? Indeed, for the first, it is necessary to introduce into solvents to increase efficiency, and for the second method of use, the solvents cannot be used, since it elapses oil films and when the load occurs, it leads to jams in friction pairs.

Judging by the results of a chemical analysis in order to achieve the stated features in Comma Petrol Engine, organic solvents are not used, and cleaning is performed due to a powerful package of detergent-dispersing additive. The peculiarity of his work is not dissolution, but peeling oil sediments that begin to drift through the system and should be captured by the filter. In systems with a small amount of deposits, this is acceptable, but for highly contaminated engines is fraught with a clogging of oil canals. Therefore, in the case of using additives on a polluted engine, we would recommend limited by a 10-minute washing cycle.

To get the maximum effect of changing the car, after draining the exhaust lubricant, the motor must be cleaned from residues and precipitation. And in this case, the question arises about the better to wash the engine before replacing the oil.

But is it worthwheeling the engine when, after this procedure, the remnants of the cleaning agent, as previously spent oil, can remain inside? According to statistics, after flushing, the engine is in 5 to 20 percent of the fluid.

Thus, depending on the quality of the work performed, in the power plant with a volume of 1.8 liters, for example, up to 400 ml of washing liquid can remain. Therefore, questions about what kind of engine flushing is better and what is worthwheeling the motor after the cut button is not harmful to the car, very relevant.

Than to wash the engine from oil

When choosing a means for cleaning the engine from oil, it is necessary to proceed from the fact that this substance should have a minimal negative effect on the fresh engine oil.

The active ingredients and additives of the latter are able to react with various flushing ingredients, causing a decrease in viscosity and foaming of lubricant.

All this affects the operational characteristics of oils, which can significantly "seek", which, ultimately, will negatively affect the performance and resource of the power unit.

Disputes about the feasibility of cleaning the engine sharpened against the background of increasing sales of used cars, as well as a general slowdown in the fleet of the fleet in the Russian Federation.

Often the acquisition of a vehicle with mileage is a cat in a bag, and the cleaning of DVS seems reasonable, because it is almost impossible to determine the state of the engine oil.

When you should clean

If you bought a car with a dubious history of the maintenance of maintenance, then think about the washing of the power unit. There are no cases when, after purchasing the desired transport, new owners discover unpleasant surprises, as impressive deposits in the upper part of the engine.

Therefore, looking after the car on the secondary market, do not be lazy to check the oil refining neck. And it is better for this to use a flashlight, in order to consider those parts that the seller could not quickly clean the earliest seller.

The question of which means to choose and how to use the engine washing, relevant and in case of changing the old oil on lubrication with another type of base. It is primarily about the transition from mineral oils on synthetic analogues.

Owners Cleaning Options

Today, the power units of the car is purified from old lubricant in various ways.

Five-minute flushing

This remedy is poured into the motor immediately before changing the engine oil, mixing with "working out". After that, the engine is running, functioning at idle for 5-10 minutes. Next follows a traditional drainage drainage, filter change and infusion of a new lubricant.

Wash oil

It uses a specialized engine lubricant, which is poured after removing the exhaust composition. Motor for some time works with this butter at idle, after which the substance is changed in the freshly car, and the filter is cleaned.

Flushing with which

This option allows you to drive a certain distance with a cleansing agent. The special substance is added to the old lubricant for about a hundred kilometers until another oil replacement, and up to this point, the car operates correctly and neatly. When the time comes, the engine oil changes according to the standard procedure.

Excessive portion of lubricant

This option is recommended to use when changing lubrication to the composition with a different basis, or for washing very dirty motors. To begin with, it is necessary to drain the spent lubricant, and pour the composition that will be used in the subsequent operation of the car.

The amount of fresh oil can only reach a liter pair. The engine runs at idle. After that, all lubricants change again to fresh, and the new filter is set.

This is the answer to the question of what washing the engine is better laundered.

Best Flushing for Motor Cooling System

For the cooling system, the engine is well fastened with water. This method allows to solve the problem quickly and with minimal cost.

The use of acids is more effective. This option provides for the use of lemon or orthophosphoric acid, which are divorced in distilled water in a proportion of 100 g per 1 liter.

The liquid, filled into the cooling system, remains there at least three-quarters of an hour. This procedure should be preceded by washing with conventional water, which is repeated after the acid discharge from the system. The final flushing with water implies 4-5 complete cycles to completely neutralize the acid medium.

Often car enthusiasts resort to flushing bite. In this case, an aqueous solution is formed in proportion 1 to 10. In order for the cleaning agent to function well, after pouring the solution to its system, it is heated to about 100 degrees Celsius.

After that, it is left in the system for about 10 hours. If during draining the solution there is no dirt and / or scale, it means it was not enough, and the procedure should be repeated.

Flushing soda also finds its use, but solely for cleaning the elements of the engine from copper and / or brass. For these purposes, 50 grams of soda are bred in a liter of ordinary water. This composition is low, but perfectly copes with the task.

In each case, the washing of the motor, which are described above, it is necessary to control the oil pressure. First of all, it concerns the "engines" with a superior and diesel engines for which the lack of lubricant is critical and unacceptable.

In the company motorists, they say that the flushing of DVS diesel fuel is very effective and economical. For these purposes, people use clean dt, and a mixture with engine oil in proportion 1 to 1.

Specialists, answering the question, the better to wash the diesel engine, are offered one of the ways described above. In addition, it should be understood that the solarium is capable of destroying various rubber seals and structural elements.

A fun transformation in the consciousness of drivers has been attracted to such a simple procedure as the engine washing when the oil is replaced. The historical experience of fathers unequivocally said that it was necessary to wash. In the era of mineral oils of dubious quality (when, besides them, in any case, there was no other in the USSR) otherwise it was simply impossible. However, the chemical industry on the spot is not worth it, and here we use a steep synthetics, which, according to the promises of the manufacturers, everything will do everything in the engine. The washing of the engine was subjected to obstruction and was already going to throw in the dump of automotive history, but while it was too early to do. Washing engine procedure, of course, outdated, but in some situations it may be by the way.

Filling of washing tools in the engine

When you do not need to wash

Supporters of technical progress, in general, right if you use high-quality synthetic oil (in extreme cases, semi-synthetic) and change it on time installed by the manufacturer, or more often, then wash you do not need. Of course, it will not be worse than the engine, but also better too. But you pay for flushing and dual replacement (or spend your time if you serve your auto yourself). Want to pamper the motor and extend its services - slightly reduce the oil replacement interval - the use of it will be more than from washing.

Many are concerned about the question - whether to rinse if you change the brand oil? If it is one level with what was flooded earlier, for example, synthetic changes to the synthetics, then it is not necessary.

Therefore, in ordinary situations, flushing is not needed. It's like medicines - no one will take potent drugs only because I want to have reasons for such a step.

When you need to wash

However, there are situations when the engine washing is very desirable.

1. You bought a car with hands and do not know her story. Used car This is always a cat in a bag, but if the body, the cabin and chassis, at least you can estimate visually, then technical fluids are a big mystery. Does the owner observed the interval of the replacement, whether good oil bought - you can not know this. There are cars with service books or checks from shops, but it is rare and still does not give warranty (such things are faked very simple). So for your own tranquility, the first replacement of oil after purchase is better to do with flushing. If everything goes fine, then you can no longer wash.

2. When moving to less high-quality oil. If you pissed your engine expensive butter, but then we decided that it is redundant (for old engines developed and produced in the last century, the expensive synthetics is not at all necessary), then when the engine is lowered in the class, the engine must be rinsed. The reason is that the old engine oil does not merge completely - if you unscrew the plug, the system remains in the system percentage of 15% of the development, if the vacuum pump is "sucking" - 5-7%, but it still eats. And dilute mineralo synthetics is not a very good idea.

3. Antifreeze got into the oil. This is an abnormal situation and here without washing anywhere. It is necessary to fully wash the remnants of antifreeze from the oil system, without forgetting to figure out the cause of mixing liquids. Perhaps rinse will need to be twice to completely clean the pallet and oil channels.

What and how to wash

There are several engine washing options.

1. Compositions like "five minutes". These are special bottles (similar issues Liqui Moly, Er, Hi-Gear, Comma, Laurel and others, cost from 200 to 500 rubles), which contain organic solvents. They need to pour into the motor before changing the oil and give to work at idle for 5-10 minutes. The compositions are rather aggressive, wash off the oil film, therefore, firstly, you should not flood them for a long time, secondly, to give a motor a larger load. There is a cleaning effect, although if the motor has a lot of deposits, there is a chance that the part of the "Bodhaya" will remain in the pallet, and does not merge along with oil. In advanced cases, after using such compositions, it is better to change the oil twice, with a reduced interval. The compositions work, although with serious motor pollution, it is rather necessary to think more about flushing, but about.

2. Wash oil. Almost every manufacturer oils have so-called washing oils in the assortment. In fact, it is a banal mineral water with a set of washing additives. It needs to be pouring into the engine and give to work at idle. The method of less aggressive, harm the motor does not bring, but can wash small old deposits. In addition, flushing oil is relatively inexpensive, so according to the price / quality ratio option is reasonable.

3. New oil. You can rinse and the same butter that you are going to fill. This is a very good option, because the new serving of oil will be mixed not with an incomprehensible substance that did not spine after cleaning, and not with washing butter, but with exactly the same composition, the path and slightly worked. Oil is usually washed into two navigations, first pour the first batch (you can at the minimum level) with a replacement, drive 2-3 days, then produce a final oil change and filter again. The method excellent allows you to move with dubious "bodiagas" to high-quality oil without harm to the motor, but expensive, it turns out to change the oil and the filter you need two times in a row.

Despite all disputes and contradictions, the situation with flushing seems quite obvious. The owners of the new cars that regularly pass, it is not needed, it is money for the wind, but when buying a used car, it makes sense when the oil is first replaced by rinse who knows what he was poured into the motor to you. But then, by going to knowingly good oil, you can forget about flushing again. If everything is bad with the motor, then no flushing will help.

For the last years, thirty car owners argue, wash the engine when replacing the oil? Let's try to deepen in the history of the question. For the first time, the washing of the oil system of the engine was introduced in the USSR to clean the lubrication system of large diesel engines. Developed a special washing liquid - low-viscous mineral oil enriched with detergent components. Approximately half an hour of operation on such washing oil was allowed to derive a certain amount of slurry and particle contaminants from the engine. As a result, the performance of the lubrication system and oil pressure was restored, several fuel consumption dropped and the engine resource increased. Adventurous (already) people decided to transfer such a flossing technology to passenger car engines and suffered. In the time of the USSR, the engine oil was a deficit, infrequently sold in stores and in spill on the gas station. The quality of the then oils was such that the Lights of 50-60 thousand km, Zhigulevsky engines were already clogged with carbon nagar. Oil filters were deficient, even got the spread of collapsible Zhigule filters with a replaceable filtering element. The deficit and low quality filters also provoked increased pollution of engines.

Approximately in the mid-80s, first washing oils began to go on sale, at the same time the automotive press, the journal "driving," began the educational work on the use of the engine washing with special washing oil (fully filtered washing).

In Europe, also faced the pollution of the engines, but went somewhat different ways. Oil oils that were washed with the engine when replacing oil in the USSR, they were expensive for Europe. Yes, and utilize the double amount of hydrocarbons (washing + old engine oil) was expensive. Therefore, special cleansing additives were developed, components that reinforce the expired operation, the detergent properties of old engine oil. Such washes are added to the old oil before it is replaced, the engine runs on a "cocktail" of a tens of minutes, then the old oil together with contaminants is drained and disposed. The capitalists considered everything, the efficiency of the washing-additive was higher than that of washing oil, and the cost of the washing procedure is lower. The safety of the washing procedure also turned out to be at height, since in washing-additives, except for detergent components, include protective, antisaded additives that protect the engine during the flushing process. In addition, after using flushing-additives in the engine, there is practically no mineral oil, which is the basis of the basis of the full-volume washing, and the residues of the solvent, on which the additive washing are based, are injected when driving the engine.

Gradually, by the beginning of the 21st century, the problem of pollution of engines in Europe has lost relevance, at the same time, in Russia, on the contrary, aggravated. The causes of steel and the quality of gasoline, and the inability of modern car owners competently handles with the technique, and sometimes the use of counterfeit oils. It was at this time that the European approach to the washing of engines when replacing the oil was widespread in Russia. Consumers understood the benefits from a clean engine: first, the washing of the engine when replacing the oil saves the resource and reduces the amount of sudden failures associated with the disruption of the lubricant. Secondly, washing, with its low cost and speed of the procedure, saves fuel, as the clean engine is easier to spin and work more efficiently. According to some engine pollution companies, it is capable of worsening its effectiveness by 20-30%.

Currently, in the automotive industry there is an irreversible trend of the transition to low-viscosity and ultra-glossy motor oils. This is done for additional fuel economy to meet the latest environmental standards not just in harmful substances, but also on greenhouse gas emissions (CO 2 and water as a pair). To use liquid oils, the engine is being finalized, especially pay attention to the finalization of the piston. Under the oil dialing rings on the piston there are drainage holes that have excess oil during the engine operation. To use low-grade oils, these holes are made very thin, and they become extremely sensitive even to small pollution. Pollution of drainage holes leads to a very fast rings, so characteristic of modern engines. The only countermeasure against this phenomenon, becomes regular, with each oil change, washing the oil system. So the engine washing technology, invented for diesel locomotives and a little modified, is now very sought-after.

What to wash?

In the engine can be two types of pollution. The first and most common species - lacquered pollution. The varnishes are formed on the heated parts of the engine, on the pistons, rings, rods of the valves, can cover the engine parts of the engine, color from light straw, to dark brown. Varnish pollution is not always possible to determine visually. Their indirect signs are elevated oil consumption, smoking, reduction of working pressure in the oil system, valve jamming, etc. Causes: Chronic engine overheating, low-grade fuel, features of the motor oil used, structural disadvantages, malfunction of operation, etc. Link pollution in two stages are laundered.

The first stage is the use of 5 or 10 minute intensive flushing added to the old oil. The second stage, fill fresh oil with good detergent properties, for the final removal of contaminants, softened after the impact of washing. The oil replacement interval should be reduced by about twice. A simple consumer will need to consult a specialist. A good choice for removing lacquer pollution will be 10-minute flushing production of Liqui Moly GmbH, for example, OilSystem Spulung High Performance Benzin (Flashing for a gasoline engine) and OilSystem Spulung High Performance Benzin Diesel (Washing for a diesel engine), as well as a professional washing agent Engine Pro-Line Motorspulung. Pro-Line Motorspulung is so strong that it is capable of removing carbon nagar on the pistons due to the effective effects of flushing vapor, and is used both in gasoline and diesel engines.

Second type of pollution - oil sludge. Usually, the black slurry is very clearly visible, if you remove the plug of the oil-tapping neck and look inside the engine. If the metal is covered with black tap, then it is sludge. The sludge is formed from poor-quality oil, exceeding the oil replacement intervals, when using poor-quality fuels and, in the oil of water condensate or antifreeze. The presence of a sludge is a signal to action, you need to clean the engine until the sludges have fallen into the friction pairs, on the grid of the oil worker and did not blocked the supply of fresh oil. Washed sludge will not work quickly, as they are formed not instantly, but gradually. To remove sludge, it is necessary to use a soft flushing of a long-term action so that the pieces of contaminants did not leave the parts and did not cause thrombosis, but gently and safely dissolved. Flushing translates pollution into a liquid state, allowing them to leave the engine along with the old butter.

We can recommend a special flushing of Liqui Moly Oil-Schlamm-Spulung. The additive must be pouring approximately 200 km to the planned oil change and roll out this mileage in calm mode. For this mileage, flushing will get to the most secluded corners of the engine, dissolving pollution, translating them into a weighted state for easy removal from the engine.

Pollution in the engine is not a sentence to overhaul, and the argument for the use of flushing before the oil change. Regular flushing for each oil replacement guarantees from the occurrence of critical pollution, especially on modern engines designed to use low-viscosity varieties of oil. Depending on the application situation, you can choose the washing of the oil system.

;

Such a concept like washing oil for the engine, is familiar, perhaps, every more or less experienced car owner. However, far to each driver faced personally with the fact of using this category of lubricants. Moreover, few have used flushing formulations for their cars.

The use of the engine washing in some cases is not just desirable, but necessary. If, of course, the car owner is interested in long-term and trouble-free operation of the motor.

But there is also the reverse side of the question when the use of lubricants or additives into flushing oil can cause negative consequences.

In the article of the article, consider flushing oils, validity of application and possible negative consequences.

Purpose of washing oil

Washing oil is intended for cleaning the engine from wear products, slags, soot, nagar and other contaminants, which are in the engine as in the free state (circulated on the lubrication system) and in the associated (deposit on the walls of the crankcase and other parts).

The most important feature of the engine cleaning is washing. No matter what form they are supplied. There are many reasons for the appearance of sediments of solid fractions in the engine.

Naar and Circles Oil In Engine

Washing oil, both for diesel and gasoline engine, should effectively wash off the deposits in the lubrication system of any origin.

In addition to the detergent function, which is paramount, flushing lubricants perform a function of lowering the acidity of the engine of the engine.

note

The fact is that any lubricant has its pH, which allows you to function in the manufacturer laid. In the process of operation, the oil is inevitably subjected to oxidation to the formation of solid algae inclusions. These oxides are settled on all available surfaces.

When replacing lubricating fluid, a part of working with oxides remains in the engine. After the fill of the new lubricant, these oxides are partially washed off from the walls and mixed with the main mass of oil, shifting the PH balance. In parallel, the ballast is clogged from hydrogen compounds.

Engine after washing oil

Another oil purpose is the urgent cleaning of the system at critical violations of the lubrication system. This can be attributed to the erroneous fill of the inappropriate lubricant, for example, cheap mineral instead of good.

Penetration into the lubrication system of a large amount of fuel or antifreeze hit to form an emulsion. In all these cases, just drain through and fill the new oil is not safe for the engine.

note

The composition of the washing oil for the engine from different manufacturers can be very different. This applies not only to the quantitative composition of detergents, dispersing and other functional additives, but also a qualitative set of package of additives. Therefore, different compositions can give a different effect depending on the specific task.

How and when to use flushing oil

Consider five common cases when the use of oil for washing the engine is reasonable, but not mandatory.

Acquisition of used car

This question is relevant if the car was purchased in a car chiel or from the reaclligence. Ask questions about the last replacement and the oil used in this case is useless. The famous fact that some additives in lubricants belonging to different classes can conflict among themselves.

Sometimes the formation of solid inclusions occurs, in some cases there is an increased foaming and accelerated oxidation, and sometimes the working quality of lubricant is simply changed without reflecting this fact on the oil structure.

Therefore, if there is no possibility to contact the owner of the car, it is better to perform a new lubricant before the fill.

Using low-quality or fake oil

There are no cases when car owners pour counterfeit products implemented under a dear brand. Well, if it's just a cheap mineral water.

Sometimes in the canes with stickers from well-known manufacturers, clarified testing or substance, which has little in common with motor lubricants is sold. This will quickly affect the operational properties of the car. Often the fact of refueling bad lubricant is obvious.

The nature of the engine and traction characteristics changes. Or, for example, on the dipstick or tube of the oil-coaling neck instead of a light oil, a black fuel oil mass is splashing after several hundred kilometers.

Naturally, draining a dirty substance and refueling good oil will not solve the problem completely. After draining in the engine will remain from 5 to 10% of the old lubricant. And here it can help the use of washing oil. The oil that was flooded earlier will almost completely remove from the system.

Transition from one type of lubricant to another

There is a commodity opinion that, as the engine wear, it is better to use fluid with less viscosity. This thesis is often reflected in the transition from on semi-synthetic or from semi-synthetic on mineral water.

A similar solution today is criticized and questioned. However, the car owners still use this method in practice. And when using a new lubricant with fundamentally other properties, it is advisable to flush the engine.

Antifreeze penetration

This malfunction is primarily manifested in the active formation of the emulsion. That is, lubricants mixed with antifreeze at the molecular level, which is no longer able to decompose on the fraction, despite the difference in the density of these liquids.

Usually, if the degree of contamination of the emulsion system has reached a critical level, the engine disassembly and mechanical cleaning is performed, and only then flushing.

But if the problem was detected in a timely manner, then after elimination of the source, it is necessary to use the flushing composition, after which the regular oil is pouring.

How to use washing oil - instruction

This is usually written in the containers in which it comes. We describe the highlights you need to know.

All means for washing engines are conventionally divided by the method of application into three categories:

• high-speed oil additives;
• oils designed for express flushing;
• washing oils that work for several tens or hundreds of kilometers mileage.

Five-minute compounds, which are added to the old oil before replacement, are the most simple in use. As a result, they received the greatest distribution today.

Motor washing sequence and some tips in this video

Their use is reduced to the fill into the engine immediately before replacing. The engine operates at idling 5-10 minutes, after which the drainage is made.

The effectiveness of this method is average. Washing-five minutes only partially removed from the surfaces of parts not very fat deposits and washed parts from light precipitation.

Full flushing oils designed for express washing are used differently. Before replacing, washing composition is purchased in the amount required to completely replace oil.

Before replacing, the development is completely merged from the engine, and the washing is poured instead. The engine starts and runs at idle the time specified in the instruction, after which the exhaust lubricant merges and refueling with regular oil. The effect of such washing is higher than from five-minute compounds.

Long-playing flushing substances are practically not applied. Present a full oil with a small resource and an abundance of detergent additives. After draining the development, such a lubricant is poured into the engine.

However, restrictions associated with the use of such funds, as well as potentially elevated engine wear during the operation of the car, when using such a washing oil, led to almost complete disappearance from the shelves.

TNK Promo (Express or Standard)

Not bad domestic washing on a mineral base from the Tyumen Oil Company. Low price and efficiency allowed this product to take their niche in the market. The compositions of TNK promo uses high-quality import additive packages.

Agip Flushing.

Inexpensive flushing oil of the largest Italian refineries. Acceptable efficiency at a small price.

Also today on the market is a huge number of additives that are applied immediately before replacement. The most effective of them, judging by the reviews, Hi-Gear and Liqui Moly.

However, these funds are negative reviews. Some car owners noticed that the additives only soften the dirt, but do not completely remove it along with working out.

What to pay attention to when choosing

To properly select the washing oil for the engine, it is necessary to be guided by at least two instructions:

• on the region and the method of applying a specific composition (indicated on the tank);
• recommendations of the car manufacturer (sometimes flushing can be limited or contraindicated).

The choice of high-quality washing oil today is not particularly acute. Domestic options confidently hold the quality bar, and the results obtained from their use are quite satisfying car owners.

Additives for washing

If you need the greatest effect, it is recommended to use expensive flushing from well-known brands. A similar choice will be fully justified. In the world of automotive lubricants for some reason, it is not customary to fake washing compositions, even from well-known and expensive manufacturers.

To say which flushing oil is better, difficult. All formulations will have some effect. And it is impossible to reliably to estimate this effect due to the large number of variables (the degrees of engine contamination, the chemical composition of pollutants, the singularities of the motor, etc.)

Conclusion

The use of washing oil for the engine makes sense in some cases. A good composition soluble qualitatively and displays solid formations on the walls of the crankcase and the parts of the motor.

It will not be superfluous to sometimes carry out the prophylactic cleaning of the engine without any reason. This is especially true in cases where low-quality engine lubricant systematically applies.
