CONSUMER ANALYSIS

PROCESSING TECHNOLOGY: you will need to install the car on a horizontal platform (in this case, the cylinder axes will take a vertical position, provided that the engine is in-line and not opposed) and warm up the engine to operating temperature. Sequence of actions: turn off the power unit, unscrew the spark plugs (gasoline internal combustion engine), injectors and glow plugs (diesel internal combustion engine). Pour 45 ml of the drug into each cylinder, then immediately close the technological holes (you can screw in the previously removed spark plugs (nozzles)) to form a “steam bath” in the combustion chambers. Then you should turn off the ignition system (short-circuit the central wire, remove the connector from the Hall sensor, etc.) to avoid sparking and possible ignition of the decarbonizing agent LAVR (LAVR) ML-202.

Leave the engine for 1 hour. After the time has passed, release the technological holes. Turn the crankshaft with the starter 2-3 times for 5-10 seconds with the accelerator pedal fully depressed to remove excess liquid and vapor from the cylinders. Install the dismantled components and parts. After this, start the engine and let it run for 5-10 minutes in variable speed mode (idling with revving), but it is not recommended to “spin” the engine by more than 2/3 of the maximum speed. Replace used oil.

DOSAGE: standard packaging of LAVR (LAVR) ML-202 contains 185 ml of decarbonizing liquid (enough to treat an engine with a volume of up to 2 liters). If the volume is larger, you will have to use a 330 ml bottle.

SUMMARY

An inexpensive drug of high quality and, what’s nice, it’s made in Russia. LAVR (LAVR) ML-202 really has all the properties declared by the manufacturer. The results of the application can be found in the table.

Werwolf

LAVR is an excellent thing, I recommend it to everyone for uneven compression across the cylinders (as a result, vibration is possible) and simply for its (compression) reduction due to coking.

In crisis conditions, many people are put in a rather tough position, from ordinary citizens to representatives of big business. The automobile market turned out to be the most susceptible to various problems, and difficulties began to appear on it at the end of 2014, because it was from that time that experts noted an increase in the service life of various cars. Every person today tries to delay as much as possible the moment when his old, proven car needs to be replaced with a new car, using a wide variety of means, one of which is “Lavr” decarbonization. Reviews about this product can be found mostly positive, but in order to finally decide on a purchase, you need to understand the principle of action and the benefits of this product.

Today, a car service is a place where drivers prefer not so much to fix various malfunctions, but rather to prevent problems related to the age and mileage of the car. An intermediate means of such prevention is specialized auto chemical products.

Let's sum it up

The washing process is similar for all brands of cars; piston rings will be decarbonized with “Lavr” on a “Nissan X Trail T31” or a domestic “Lada”. The main thing is to follow the instructions established by the manufacturer. Even decarbonization of a heavily contaminated system with the removal of spark plugs is best done regularly. This will prevent the appearance of new carbon deposits in the combustion chamber.

Many drivers are sure that cheap flushing cannot have a positive effect. But if you look at the composition of the product, it is almost similar to that used in Hi-Gear or Liquid-Molly. Therefore, there is no particular point in overpaying for a brand. Today there are both supporters and opponents of flushing piston rings. Of course, everyone must decide for themselves. But the fact that there is a result is an obvious fact. In some cases, only a major overhaul can help, but this is a completely different topic for discussion.

How did she appear?

Immediately after various cars began to actively spread in the USSR, every owner knew that it was necessary to periodically clean the piston rings from various contaminants. At the same time, fuel in those days burned much worse compared to today, and sludge formed on the surface of parts quite quickly. Today, everyone can do decoking with “Lavr” to get rid of such faults, but back then they had to come up with something else.

The oil was also of much lower quality, so it oxidized quite quickly on the cylinder walls, forming a film and getting into the piston grooves. Among other things, during the combustion of fuel, soot gradually formed, mixing with this film, thus forming extremely persistent solid deposits that block the operation of the pistons.

Motorists tried to combat such pollution by any available means, for example, leaving kerosene in the engine overnight, and over time they began to use special solvents more often. Desperate car owners did not stop at the risk of being left without any means of transportation. In addition, the effectiveness of such compositions was practically absent, and even today many car enthusiasts are not afraid to experiment to their own detriment. Some have completely forgotten that such a procedure needs to be carried out, relying entirely on additives that are added to modern oils, as well as relatively high fuel standards.

Origin story

Since the widespread use of cars in the USSR, every driver knows that in order for his iron friend to serve as long as possible, he needs to regularly clean the piston rings from various contaminants. It is worth considering that in the old days, fuel burned much worse than it does now, and a very large amount of slag accumulated on the surface of the working mechanisms.

Today, “Lavrom” decarbonization, reviews of which can be read in this article, will help you quickly cope with such troubles. In the old days, humanity was forced to come up with other cleaning methods.

The engine oil was also not of such quality. It oxidized very quickly, getting into the piston grooves. In addition, during fuel combustion, a huge amount of soot was formed, resulting in very persistent solid deposits that caused pistons to malfunction.

Noticing such problems, motorists began to think about methods for conservative solutions. First, they poured kerosene into the engine and left it there all night. And only later did specialists develop special solvents. However, most often such compounds were absolutely ineffective, and sometimes also caused significant damage to the car. But science does not stand still. Decarbonizing “Lavrom”, reviews of which you can read in this article, is in great demand, as it copes well with the task assigned to it. But still, it is not as omnipotent as many drivers believe.

How does LAVR help delay major repairs?

It is quite natural that engine overhaul is the most terrible event for most car enthusiasts, since this is a colossal expense, and the need for such a procedure indicates that the car is currently completely unsuitable for use. That is why, in order to avoid such situations, a special decarbonization “Lavrom” is used. Reviews say that the savings with the help of such a product are quite noticeable, because today the cost of overhauling most middle and budget class cars fluctuates around 50,000 rubles, while the drug costs only 400. But this remedy is not a panacea that gets rid of the need for repairs, but only prevention, so it will be useful to understand whether serious savings are actually being achieved.

Is decoking necessary?

Before using Lavra, it is advisable to understand the problem in more detail. For example, on many car models, oil scraper and compression rings last about 150-200 thousand kilometers, although there are examples that last 500 thousand. Much depends on the design features of the power unit and its operating modes. There are several ways to test rings, although they are more indirect than explicit. High consumption of engine oil in the absence of leaks indicates that the oil scraper rings are stuck and the lubricant is burning in the chamber. If, when starting the engine, and in particularly advanced cases, while driving, bluish smoke is noticeable, then this also indicates problems with the rings.

It also makes sense to check the spark plugs. If they turn black from the oil, then again this indicates a problem with the rings. In this case, you need to buy a product for decarbonizing piston rings “Lavr” and try cleaning the system. If everything works out, consider yourself lucky.

New trend of car services

It is worth noting the fact that today even many car services have gradually begun to include in their price list such a service as Lavr decarbonization. Feedback from experts on this matter suggests that this is quite a profitable activity, since not all car enthusiasts can carry out this procedure on their own, despite the fact that they have this opportunity. For professionals, this is not a labor-intensive procedure, and it can easily be carried out on the street, since it does not involve the need to place the car in a service center. Thus, many companies ensure genuine gratitude from customers and a more active flow of them, and, consequently, profit. All this is ensured by Lavr decarbonization. Reviews from experts indicate that the flow of cars for this procedure is almost continuous. The reason is that it needs to be carried out every year or every 30,000 km, which means that a person who has already carried it out is guaranteed to become a regular customer of this service.

Popular car service

In many car services you can see a new one. “Lavr”, reviews of which are mostly positive, has proven itself well among auto mechanics. That is why this service is in great demand. In addition, providing such a service is very profitable, because not all car owners can do it themselves. However, for experienced professionals, this procedure is very simple and quick. This can be done even on the street. Take a look at any car service center and you will see that the flow of cars eager to carry out this procedure is endless. All this is easily achieved by decoking the rings. “Laurel” - reviews from specialists are quite good, it helps to keep the mechanism in satisfactory condition longer. Clients are satisfied and return for a repeat procedure every thirty thousand kilometers or once a year.

What are the advantages?

“Lavr” liquid for engine decarbonization is absolutely safe for various equipment, so its use completely eliminates the possibility of any conflict situations or complaints from customers.

The procedure is extremely easy to use, so the owner of such a business does not have to allocate additional funds to train specialists - just read the instructions for the drug and follow it correctly. If the “Lavr” liquid for engine decarbonization is dosed correctly, the consumption of the drug in a car service can even be recorded.

It is worth noting that this procedure was carried out by Soviet car enthusiasts, but LAVR is the first company to release the drug to the mass market, and at the moment there are no products that would surpass ML 202 in their technical characteristics. A separate advantage of this product is that that the car service does not need to allocate additional costs for equipment, since all the tools necessary for the procedure are included in the packaging of the drug itself, which is another significant advantage.

Advantages of this tool

“Lavr” - decarbonization, the instructions for use of which are described in this article, is considered completely safe for equipment of any kind, therefore, during its use, cases of negative reactions in the equipment are excluded.

It is worth considering that this procedure is very easy to carry out, so car dealership owners do not need to look for specially trained technicians for it. It will be enough just to carefully study the instructions for use and use it without question. In addition, the product, with the correct dosage, is very economical.

Similar products were used back in the Soviet Union, but Lavr is the first company to make its product for mass use.

Another advantage of this drug is that the owner of a car dealership does not have to allocate money to purchase special equipment and tools. All necessary accessories will come in the package.

Modern engines do not require decoking

Of course, over the past few years the situation with oil and fuel has improved significantly, because in Soviet times, few could even start without using a blowtorch, but despite this, the problem of coking not only did not disappear, but also seriously worsened. Technologies have become more advanced, the gaps between the grooves and piston rings have decreased, but this ultimately led to greater vulnerability of modern systems. Also, a small layer of deposits ultimately leads to engine malfunctions; over time, deposits accumulate more and more, and the problems only become more serious - compression drops, detonation occurs, wear accelerates, and then serious breakdowns appear. If you are not going to spend money on major repairs, then proper decarbonization with “Lavr” can help.

Do-it-yourself “soft” washing

In this case, there is no need to remove the injectors, since “Laurel” is added directly to the fuel. A half-liter bottle is poured into the tank before refueling. Next, it is advisable to fill in from 40 to 60 liters of gasoline and use it completely, again, without refueling. It is advisable to repeat the procedure every 2-3 thousand kilometers.

Again, “Lavr” for decoking piston rings will not help if the system is dirty. But if you use such a product on a new car, and do it regularly, then you can keep the fuel system clean for a very long time. This product has a number of advantages. Firstly, even a beginner can cope with such washing. Secondly, after use, a protective film is created on the walls of the parts, which prevents the formation of new carbon deposits for a certain time.

Additives and flushing liquids

Many believe that these procedures save you from any problems, so decarbonization is not at all necessary. In fact, the most effective way to remove various deposits is through “immersion,” when the decarbonizing composition is poured directly into the cylinders. At the same time, getting to the technological holes is not so easy, and you have to use special tools, as well as create comfortable conditions for yourself (it is better not to carry out such work outside in bad weather). That is why it is recommended to decoke the engine during a scheduled replacement of spark plugs or oil.

Why should you choose Lavr piston ring decoking liquid?

The first thing most motorists pay attention to is the cost of the cleaning product. "Laurel" is not the cheapest option, but one of the most popular. The fact is that almost all rinses are the same in composition, the only difference is good advertising. You must also understand that all flushing agents are harmful to rubber gaskets and seals, which is why they cannot be used constantly or on a car where the condition of the rubber gaskets is not the best. This can lead to oil leaks, which will be difficult to eliminate.

However, “Lavr” is considered the most neutral to car tires. This is why many people prefer it. What is also important is efficiency and clear instructions. Decarbonization of piston rings “Lavr” is a completely domestic product. How to use it, as well as the dosage, is written on the label in Russian. In general, along with Winx, this is a clear leader among washes on the domestic market.

The liquid must perfectly clean the surface

“Lavr” is a preparation that cleans medium and high degrees of coking, but it often happens that in old engines the deposits have already become so “bored” to the parts that they hold on to them like cement mortar, and even cleaning such systems is white Not recommended. It is also worth noting the fact that solutions that are too caustic can cause engine damage.

But in any case, LAVR is considered a more effective product compared to analogues and standard solvents.

Is it possible to do without decoking?

Engine temperature does not rise: what should the driver do?
Many car owners think that carrying out procedures such as flushing with fluid and additives are considered excellent methods for solving engine problems. However, this is not the case. The most effective cleaning method is full immersion. In this case, a special decoking composition will be poured directly into the cylinders. However, doing this with bare hands is not so easy. There is no way to carry out this procedure without the use of special tools.

Please note that such work should not be carried out outdoors during the cold season. Try to create the most comfortable conditions for yourself

It is best to decarbonize the engine during a previously scheduled oil or spark plug change.

How is this procedure carried out?

Now let's talk about how Laurel liquid is used. Decarbonization (instructions below) does not take much time if you follow the instructions for this product correctly and choose the right dosage. The procedure itself is done as follows:

• The engine warms up to operating temperature, which should be more than 70 ⁰C.
• The ignition system is turned off. To do this, you can remove the connector from the ignition coil or Hall sensor. Thanks to this, you can get rid of possible ignition of the vapors of this drug, as well as damage to various elements of the system.
• The spark plugs are removed. If the procedure is carried out in a diesel engine, the glow plugs or injectors are removed.
• The pistons are set to a position close to the middle one, while the crankshaft must be rotated by the pulley nut or using the drive wheel when the gears are engaged. To determine the position of the piston, you can use a long feeler gauge inserted through the process hole.
• Using a syringe, pour an equal volume of Laurel decarbonizing liquid into each cylinder. After this, close the technological holes so that a “steam bath” is formed in the combustion chamber.
• Now we have to wait. For an express procedure, you need to wait at least one hour, but in case of serious coking, the exposure time of the drug should increase up to 12 hours. In order for the liquid to more efficiently seep into the lower part of the cylinders, the pistons can be periodically moved in different directions.
• Clear technological holes. The remaining liquid is removed with a syringe, after which the cylinders are purged with compressed air. Now you will need to fully depress the accelerator pedal, and then turn the engine shaft using the starter two or three times for five seconds. In this case, it is recommended to cover the technological holes with some thick cloth so that the decarbonizing agent for Laurel rings does not splash out.
• Install dismantled parts and assemblies. Be sure to additionally check for correct assembly.
• Start the engine and let it idle for 5-10 minutes to reach operating temperature. It’s worth noting right away that short-term smoke may appear, since the liquid for decarbonizing the “Lavr” rings remaining inside will burn out, and this smoke is not dangerous for the catalysts.
• Clean the engine with a product designed for flushing the lubrication system, or with a special product LAVR.
• To completely get rid of carbon deposits, it is recommended to drive the first few kilometers at slightly higher speeds.

This is the proposed decarbonization. The instructions are extremely simple, and the work can be carried out by experienced motorists in a garage, so if you are confident in your abilities, you do not necessarily need to turn to the services of car services.

What should you expect from a flush?

As noted above, if the system is heavily contaminated with carbon deposits, you should not completely rely on flushing. Often “Lavr” copes with the most difficult cases, but this does not always happen. If flushing helped, you can notice this from the first start of the engine, because it will run more smoothly. This also applies to idle speed, which usually stops floating. The dynamics of the car also increases noticeably. This is especially true for those systems that have been heavily contaminated. In this case, the engine begins to pull much better.

Approximately 80% of reviews indicate that there really is an effect. Of course, many experts note that the best effect is achieved with regular use of Lavra as a fuel additive. This helps keep the piston rings in perfect condition. In this case, the resource of the power unit increases, but its characteristics do not decrease. In general, with the right approach, you can expect smoother engine operation and improved dynamic performance. You can also expect a slight reduction in fuel consumption.
