How many minutes to flush the engine with flushing oil. What is the best way to flush the engine before changing the oil. Features of flushing the engine with various means

During the operation of the car, carbon compounds are formed on the internal surfaces of the engine and in the channels of the lubrication system. Their appearance is inevitable, and this problem cannot be solved simply by using engine oil High Quality. Also, do not forget that when draining old, used oil, some of it remains inside the engine. What does this mean for the car?

When you pour new oil into the engine, the additives contained in it will immediately begin to interact with deposits and contaminants. This can lead to various negative impacts, including:

• partial clogging of the oil filter;
• premature production of an additive package, loss of performance properties of recently filled oil.

How to be in this situation? It is necessary to use special flushing agents, thanks to which the engine will run efficiently and smoothly after changing the engine oil.

How often should flushing be done? This should be done every time you change the oil or oil filter.

How to choose an engine flush? The obvious option is to use fresh engine oil. In this case, everything is simple: you need to drain the old oil and fill in new. After the engine has been running for a while, the oil used as a flush is drained and fresh again. This approach provides good result, but it has a serious drawback - high price. Using oil as an engine flush means you pay twice for it.

The next option is to use a special flushing oil. This flush is poured into car engine after draining the old oil, after which it needs to work for about 15-20 minutes for Idling. Usually this product is created on a mineral basis, which makes it affordable. Then you change the filter and drain the used engine flush, replacing it with fresh oil. Unfortunately, such products cannot be drained completely, some part inevitably remains in the internal cavities, mixes with fresh oil, worsens its viscosity and other performance properties.

The best option is flushing, which is called the "five-minute", as well as other similar products. This tool is a set of additives that is poured into old oil, mixed with it and effectively removes contaminants and deposits formed in the engine. This wash has many advantages. She:

• restores the mobility of compression and oil scraper piston rings;
• improves heat dissipation;
• minimizes engine wear, increases its resource;
• makes it easier to drain old oil.

Separately, it is worth noting the safety of such flushes for rubber seals, oil seals, valve stem seals.

In some cases, it is necessary to use the so-called professional flushes that can cope with the most difficult tasks of cleaning engines from contamination. How are they different from regular products? In professional washing, the content of active ingredients is increased. They are recommended for use in the following cases:

• the constant use of mineral oils of insufficient quality (flushing should be used at least once every three oil changes);
• severe overheating of the engine and the resulting formation of soot;
• frequent use of fuel of dubious quality;
• obvious engine malfunctions - poor start-up, loss of compression, smoke, and so on;
• significant excess of the oil change interval;
• constant strong knock of hydraulic lifters caused by clogging of the oil supply line.

For washing heavily worn engines, special products are used that are designed for effective and at the same time gentle cleaning. The fact is that during cleaning, large fragments of deposits can form that can harm interacting parts. The use of special flushes allows deposits and contaminants to be transferred into low-dispersion phases that cannot damage the engine.

High quality washes from Liqui Moly

Liqui Moly manufactures high quality products, allowing to cope with deposits and pollution formed in the engine. They make oil changes easier and more efficient.

The following washes are examples:

• Engine Flush - a fast-acting substance, "five-minute", with which you can flush the engine during a regular oil change;
• Oilsystem Spulung Light - soft cleaner oil system, easy to use and extremely effective;
• Oil-Schlamm-Spulung - a product of enhanced action, which makes it possible to flush the engine with strong contamination and get rid of the sludge formed in the system after prolonged overheating;
• Oilsystem Spulung High Performance Diesel is a powerful cleaner designed to remove contaminants from a diesel engine.

Every Liqui Moly rinse is carefully formulated, tested and proven to work. A wide range allows you to find a solution for each specific case.

The engine oil needs to be changed, everyone knows that. Over time, even the best lubricant loses quality and is not able to protect rubbing parts. This leads to accelerated wear of parts. Oil loses its properties according to natural principles:

1. Under influence high temperatures the chemicals in the composition are oxidized.
2. Manufacturers include useful additives in modern lubricants. Additives prevent the combustion products and friction from settling on the parts. Particles of coke and metal, soot are mixed with the lubricant, and remain in suspension.

After changing the oil in the engine gradually turns from light to black. This happens because the grease accumulates contaminants. When their number exceeds the limit, the oil can no longer lubricate engine parts.

1. If the machine is operated infrequently, the oil still loses its key properties. Grease is always in contact with air. And the oxygen contained in it actively oxidizes oil products.
2. In addition, there are engine oils for different temperature conditions. Unlike all-weather, they need to be changed in spring and autumn. If the lubricant is designed for summer temperatures, then it will make it difficult to start the engine in cold weather. On the contrary, a lubricant that allows you to start in the winter may lose viscosity in the summer.

How often to change the oil

As a rule, car manufacturers recommend a replacement interval of 10,000 km. This mileage is indicated in the technical documents of the vehicle. These regulations should be observed if you rarely stand in traffic jams, use quality fuel prefer a calm driving style. Most cars are recommended to change the engine oil more frequently, at least once every 7500 km.

Here is a list of circumstances that shorten the service life and require more frequent replacement oils:

• The power plant often runs at high speeds.
• The car is stuck in traffic every day. This item is relevant for all major cities.
• Low quality fuel is used.
• The car travels short distances. From starting the engine to stopping it takes less than 30 minutes.
• The car often drives on a dirt or dusty road.

If at least one of the circumstances is familiar to you, you need to change the oil more often than the car's service book requires.

How much lube is needed

For each engine, the volume of the lubrication system is individual. The exact figure is indicated in the instruction manual. The design of some motors does not allow to completely merge mining. Therefore, we recommend that you monitor the level. Note that the lubrication level will be higher when operating temperature motor.

Even on a new car, regularly check the amount of grease in the carriage. Make it simple. Warm up the engine and turn it off. Remove the dipstick after 5 minutes. The mark should be between the upper and lower limits on the dipstick. This is the norm. However, it is not necessary to always maintain the highest level of lubrication. In striving for this, there is a danger of overflow.

It is a common misconception that excess lubricant does not lead to consequences. What can happen if you exceed the permissible level:

• Excess oil will burn out while the engine is running. In this case, the amount of burning in the exhaust gases will instantly rise. In such conditions, lambda probes are the first to suffer, and the catalyst resource is reduced.
• The high pressure generated in the motor will damage the rubber parts of the motor. Leakage will begin through the cracks in the seals and gaskets.

To fix the damage will have to spend a round sum. Therefore, always keep an eye on the volume that you add to the engine.

Need to flush the engine when changing the oil or not

• Flushing the engine will not only wash off the dirt, but will also remove the important additives contained in the lubricant.
• After washing, the dirt from the filter will settle on the engine parts.
• The compatibility of modern oils allows you not to flush the engine even when switching from one class of lubricant to another.

In order not to fall victim to erroneous statements, let's take a closer look at each of them:

1. Engine washes do not affect the coating formed by anti-wear additives. Only those elements that are dangerous for the motor are displayed.
2. Oil recipes are unique. Each brand has its own approach and its own secrets of composition. A number of manufacturers rely on the high quality of the basis of the recipe. Other brands improve the properties of the lubricant through additives. Supplement recipes are kept secret. Therefore, the compatibility of different brands is just a myth.

It is difficult to predict how the additives of different oils will interact.

Foaming, the appearance of a resinous precipitate, and a decrease in lubricating properties are possible. To avoid such problems, when changing the manufacturer, class, viscosity of the lubricating fluid, flush before changing the engine oil.

The filter captures only insoluble particles. If the element has accumulated soluble contaminants, then the engine uses low-quality engine oil. Stay away from this kind of lubricant.

To remove soluble contaminants is the primary task of washings. Considering what kind of fuel and what lubricants we have to use, this procedure is recommended to be carried out together with each oil change.

How to flush the engine?

There is no consensus on this issue either. Supporters of flushing before changing the engine oil are divided into fans of flushing oils, express flushes and adepts of solvent and witnesses of acetone. The latter believed in the miraculous power of solvents so much that they are used for any, even the most inopportune occasion.

If we talk about the choice of flushing oils, then their use has a number of disadvantages:

• up to 20% of the oil volume remains in the engine, which cannot be drained;
• today there are only a few high-quality flushing lubricants on the market. Manufacturers save on ingredients. Therefore, they do not provide required level protection;
• rinsing with oil takes longer than using express rinsings.

The optimal washing method is the use of express washes. These are compounds, for example, 5-minutes, which speed up the process of changing the lubricant, and flush the engine. Before draining the waste, a 5-minute flush is poured into the engine so that the engine runs on the old lubricant with the addition of the drug. The composition will remove contaminants, dissolve them in the volume of oil and reduce the amount of non-drainable residue (viscosity will decrease within the acceptable range, but it will be better to merge).

There is also a soft wash LAVR engine. This is filled 200 km before an oil change. And just before replacing, you can use a five-minute flush. By the way, these engine flushes can be bought at.

Oil change steps

Watch the video on how to change the engine oil with your own hands.

1. First, we specify how much oil is poured into the engine. We look for information in the manual or on the Internet. Be careful, one brand of car may have several options power plant with different volume of oil system.
2. We start the engine and warm up to a temperature of 80-90C. We muffle.
3. Open the oil filler cap, pour a 5-minute LAVR engine flush into the engine.
4. We start the engine, let it idle for 5 minutes.
5. We roll the car into a pit, overpass or lift, turn off the engine, unscrew the oil filler cap.
6. We install a container with a volume of more than 4 liters under the drain hole. a suitable container, unscrew the plug and drain the used oil. Caution, dripping oil is hot.
7. Carefully remove the oil filter.
8. Pour a small amount of fresh oil into the new filter. We put the filter in place.
9. Change the drain plug gasket and screw it back on.
10. Pour fresh oil into the engine in parts. We monitor the level so as not to overfill. Fresh oil flows down for a long time, it takes more time for the dipstick to show the exact level. As soon as we have reached the desired level (between the upper and lower marks on the dipstick), we twist the filler neck.
11. We start the engine. We wait a few seconds until the oil pressure lamp goes out. Then let the motor run for a few minutes.
12. We turn off the engine. After 5-10 minutes, we check the amount of oil in the engine. Top up if needed.

Permissible oil consumption

If for some engines oil consumption is a common occurrence, and automakers know about it. That is the normal state of other units, when between replacements the level does not drop even a millimeter. As a rule, the technical documentation contains information on the permissible oil consumption for a particular engine. Before making a diagnosis yourself, read more about the motor, perhaps your fears about the condition of the engine will be in vain.

However, if the motor began to show exorbitant appetite, and from replacement to replacement you add more than 1 liter of lubricant, there is reason to think about the condition of the cylinder-piston group and conduct professional engine diagnostics.

A funny transformation in the minds of drivers has undergone such a simple procedure as flushing the engine when changing the oil. The historical experience of the fathers unequivocally said that it was necessary to flush. In the era of mineral oils of dubious quality (when there was no other besides them, at least in the USSR), it was simply impossible to do otherwise. However, the chemical industry does not stand still, and here we are using cool synthetics, which, according to the promises of manufacturers, will do everything in the motor itself. The engine flush was obstructed and was about to be thrown into a landfill automotive history but it's still too early to do so. Flushing the engine is, of course, an outdated procedure, but in some situations it may come in handy.

Filling flushing agent into the engine

When not to wash

Proponents of technological progress, in general, are right, if you use a quality synthetic oil(in extreme cases, semi-synthetics) and change it at the time set by the manufacturer, or more often, then you don't need a flush. Certainly, worse for the engine won't, but it's better too. But you will pay for flushing and for a double replacement (or waste your time if you service the car yourself). If you want to pamper the engine and prolong its service life - slightly shorten the oil change interval - the benefits of this will be more than flushing.

Many people are concerned about the question - should you flush if you change the brand of oil? If it is the same level as what was filled earlier, for example, synthetics are changed to synthetics, then it is not necessary.

Therefore, in normal situations, flushing is not necessary. It's like with drugs - no one will take potent drugs just because they want to, for such a step, reasons are needed.

When to wash

However, there are situations when flushing the engine is highly desirable.

1. You bought a car from your hands and do not know its history. A used car is always a pig in a poke, but if the body, interior and chassis can at least be assessed visually, technical fluids are a big mystery. Did the owner observe the replacement interval, did he buy good oil- you can't know that. There are cars with service books or receipts from stores, but this is rare and still does not give a guarantee (such things are very easy to fake). So for your own peace of mind, it is better to do the first oil change after purchase with flushing. If everything goes well, then you can no longer rinse.

2. When switching to a lower quality oil. If you pampered your engine with expensive oil, but then decided that it was redundant (for old engines designed and manufactured in the last century, expensive synthetics are not at all necessary), then when you lower the oil class, you need to flush the engine. The reason is that the old oil from the engine is not completely drained - if the plug is unscrewed, then 15% of waste remains in the system, if it is “sucked off” with a vacuum pump - 5-7%, but it is still there. And diluting mineral water with synthetics is not a good idea.

3. Antifreeze got into the oil. This is an emergency situation and here there is nowhere without flushing. It is necessary to completely wash out the remnants of antifreeze from the oil system, not forgetting to deal with the cause of the mixing of liquids. It may be necessary to flush twice to completely clean the sump and oil channels.

What and how to wash

There are several options for flushing the engine.

1. Compositions of the "five-minute" type. These are special bottles (similar ones are produced by Liqui Moly, ER, Hi-Gear, Comma, Lavr and others, costing from 200 to 500 rubles), which contain organic solvents. They need to be poured into the engine before changing the oil and let it idle for 5-10 minutes. The compositions are quite aggressive, they wash off the oil film, therefore, firstly, you should not fill them for a long time, and secondly, give the motor a heavy load. There is a washing effect, although if the motor has a lot of deposits, it is likely that part of the “bodyagi” will remain in the sump and not merge with the oil. In advanced cases, after using such compounds, it is better to change the oil twice, with a reduced interval. The compounds work, although in case of serious contamination of the motor, it is rather necessary to think not about flushing, but about.

2. flushing oil. Almost every oil manufacturer has a range of so-called flushing oils. In fact, this is a banal mineral water with a set of detergent additives. It must be poured into the engine and allowed to run at idle. The method is less aggressive, does not harm the motor, but it can wash out small old deposits. In addition, flushing oil is relatively inexpensive, so the price / quality ratio is a reasonable option.

3. New oil. You can rinse with the same oil that you are going to pour. This is very a good option, because a new portion of oil will not be mixed with an incomprehensible substance that did not merge after cleaning, and not with flushing oil, but with exactly the same composition, way and a little worked. Oil is usually washed in two passes, first the first batch is poured (it is possible to the minimum level) with a replacement, they drive for 2-3 days, then they make the final oil change and filter again. The method perfectly allows you to switch from a dubious "bodyagi" to high-quality oil without harm to the motor, but it is expensive, it turns out to change the oil and the filter needs to be changed twice in a row.

Despite all the controversy and controversy, the situation with flushing seems quite obvious. Owners of new cars who regularly undergo MOT don’t need it, it’s a waste of money, but when buying a used car, it makes sense to flush the oil at the first oil change, who knows what was poured into the engine before you. But then, switching to obviously good oil, you can forget about flushing again. If everything is already bad with the motor, then no flushing will help.

Such a topic as flushing the engine when changing the oil is of interest to many motorists. Experts conducted a detailed analysis of this issue and drew conclusions.

If you look under the valve cover where the oil filter is located, you can see that a large amount of dirt accumulates in the engine.

The answer to the question: "Do I need to flush the engine when changing the oil?" can only be given by a highly qualified specialist.

When is flushing necessary?

1. When switching from one brand of motor mixture to another. This includes such varieties of oil as semi-synthetic, mineral and synthetic. Particular attention is drawn to such an indicator as viscosity. Oil different manufacturers should not be mixed in an engine because each individual brand has its own unique set of additives. Under no circumstances should they be mixed with each other.
2. After buying a car that has already been in use. Many drivers don't know what kind of oil the previous driver used for their car. It is best to flush the motor to avoid serious problems in its operation.
3. The engine flush oil must be changed during intensive use of the vehicle. This applies to those cases when drivers drive fast and drive a long distance. All parts need more intensive and regular lubrication. This means that all wear products need to be permanently removed.
4. Owners of cars that are equipped with a turbocharged engine must buy oil highest quality. It is necessary to pay attention to its crystal clearness. Dirt and other impurities can damage car parts.
5. After the dismantling of the motor, with its subsequent complete disassembly. In this case, qualified mechanics recommend washing all components manually with kerosene, diesel fuel or gasoline. Flushing the engine is a rather laborious process that requires certain knowledge and little experience. This stage is considered the most effective. To find out how to flush the engine, it is best to contact a qualified technician. Diesel fuel is a product of oil distillation, which is used not only as a fuel, but also for lubricating engine parts.

When is it not necessary to clean the engine?

A large number of motorists are wondering: is it necessary to flush the engine when changing the oil.

Experts have identified several cases when flushing the engine is not needed:

1. After acquisition new car in a car showroom.
2. With timely and proper maintenance of the vehicle at specialized stations Maintenance with an excellent reputation.
3. If high quality engine flush oil was used.
4. The engine was flushed and the oil changed on time. Today, engine flush oils include a complete set of necessary additives in their composition. Their main purpose is to thoroughly clean the engine. Absolutely all dirt particles will be washed out with the engine fluid.

If you entrust the flushing of the motor to an unqualified specialist, then you can cause serious damage to your own car. After draining the engine, a certain part of it may remain directly in the pan. After that, it will be mixed with lubricating mixtures, resulting in a slight change in basic characteristics and viscosity.

What methods and means are effective?

Today there is a wide range and choice of lubricants on the market. automotive market. During the purchase, the main thing is not to make a mistake with the choice and not to harm your car.

To decide how to flush the engine, you need to read the tips below:

• Special oil for cleaning the engine from impurities. This method is the most ineffective. After performing such work, the concentration of dirt in the existing liquid decreases. Deposits and other impurities will not be completely washed away or dissolved.
• Flushing the engine with a vacuum pump. This is also an ineffective method that has been tested for more than a dozen years. The vacuum pump is used at service stations only in cases where it is necessary to change the oil in the shortest possible time. Some experts are convinced that pumps are capable of completely pumping out all the impurities and dirty residues present. But this statement is erroneous and does not bring the expected results. Today, such pumps have not yet been invented that are able to wash even hidden cavities. This also applies to the dissolution of dirt on the walls of the engine.
• Fast flushing of the engine with special solvents. Their main principle of operation is speed. The liquid must be poured into the motor for ten minutes and then turn on the motor. It should work a little, after which you can drain this liquid. After lengthy research and careful analysis, it became clear that they are ineffective and can cause irreparable damage to the internal parts of the engine. Special quick flushes cannot deal with dirt or dissolve it in a short period of time. After such exposure, the oil channels become clogged with deposits, and the required amount does not enter the motor. lubricant. This leads to its further failure. The most concentrated engine flush oils in some situations can cope with their main task and rid the engine of deposits. But there is a huge risk that they will violate the integrity of the rubber seals. After such an engine flush, you will have to repair the car and buy spare parts, which are not cheap today.
• The most efficient and effective method engine cleaning is the use of a long-acting flush. Before changing the oil in the engine, you need to fill in such a liquid. Next, you need to drive from 50-500 kilometers, after which the old oil is drained and a new one is poured in its place. Over this entire period of time, absolutely all deposits will have time not only to wash off the engine, but even to dissolve. At the same time, all parts and components are not harmed.

How to properly flush?

In order to flush the engine when changing the oil and at the same time not harm your own car, you must first consult with a highly qualified specialist.

He must have a lot of experience in order to correctly and accurately determine the condition of the vehicle.

Before performing such work, it is imperative to make a complete diagnosis of the machine and its engine. Experts will assess its degree of contamination and the timing of the oil change. The final decision depends on the intensity of operation and the condition of the lubricant used.

Some motorists believe that engine flushing can be done as a preventive measure. But this opinion is absolutely wrong. These actions cause maximum damage to the car engine, after which it will be required partial replacement its details.

Flushing to maintain cleanliness in the motor is only possible in certain cases. Before this, the specialist must necessarily assess the condition of the system and its purity.

Of the large number of methods and methods used, it was possible to determine the most effective cleaning of the motor from various deposits.

To do this, you need to follow a number of simple steps:

• the old lubricating mixture is drained;
• a high-quality engine cleaner is poured. Next, you need to turn on the engine in which the product is located for twenty minutes. The motor must be idling;
• then the waste liquid must be drained;
• a low-quality product is taken and the engine is turned on again to idle. At this stage of flushing, the engine should run for one hour;
• low-quality liquid is drained;
• then motorists must fill the engine with good and proven oil.

Existing types of flushing oils

Today, the automotive market offers a wide and varied selection of engine oils. Each manufacturer tries to make a beautiful and eye-catching advertisement for their product, while not forgetting to list all the benefits.

But after the acquisition, drivers and craftsmen at service stations note that there is simply nothing new in such a proposal.

There are two main types of motor oil:

1. Prolonged exposure. This special liquid must be poured directly into the engine after the person has previously drained the old one. After that, it is important to drive the car for about two days, for a thorough cleaning of all parts and components.
2. Fast acting oil. On average, it lasts for ten minutes. It is necessary to fill in such a liquid after a thorough drain of mining. Such oils are able to clean the engine during idling.

The greatest demand and popularity are additives in their pure form. They are produced worldwide famous company LiquiMoly, which has won the trust of many motorists. The presented additives for a certain amount of time before further replacement must be added to the oil.

They will gradually do their job and thoroughly clean the motor from blockages. As noted above, this is a fairly effective and efficient method. Additives do not harm the car, and also have a beneficial effect on the entire system.

The composition of the flushing oil includes such components as:

• High quality base. Manufacturers use mineral industrial oil. The most common types are I-40 or I-20.
• A certain part of the aggressive additives. These ingredients are able to effectively dissolve all the dirt that has accumulated in the engine over a certain amount of time.
• Additional supplements. These components are capable of minimizing negative impact flushing on various engine components.

Long-term washings have a gentle effect on the motor, as well as on all rubber products. When industrial oil is poured into the engine, the driver must take several precautions. Experts recommend using vehicle exclusively in gentle mode.

Among drivers, another common way to clean a car engine is in special demand - this is varietal oil. It is this one. The presented method of flushing the engine uses a huge number of official service stations and dealerships.

From time to time, car engines need to change the oil. This operation is not difficult. However, often car owners are interested in the question, is it necessary to flush the engine? We will figure out how, when and why it is necessary to flush the engine. Now most people turn to car services for these purposes, but this does not guarantee that the procedure will be performed correctly.

Does the engine need a flush?

Deciding whether to flush the car engine should be based on each specific case. If you fill in high-quality engine oil in a timely manner, then no more cleaning will be needed.

This is achieved due to the fact that any good car oil contains several additives and at least one of them constantly cleans all internal parts.

But if the car was recently purchased and the history of its maintenance is unknown, or a decision was made to replace the lubricating fluid and the question arose whether it was necessary to flush the engine when changing the oil, then the answer is unequivocal - yes.

However, it must be remembered that each engine requires a lubricant with certain qualities and a special composition. This is the only way to achieve normal and long-term operation of the motor.

So, flushing the engine must be carried out if:

• The vehicle was purchased recently and there is a possibility that regular oil changes have not been carried out in the past.
• Produced repair work for implementation, which required opening the cylinder head.
• The brand or manufacturer changes.
• There is reason to suspect that fuel, antifreeze got into the engine, or poor quality lubricant was poured into it.
• It was decided to change the oil viscosity or composition (for example, from synthetic to semi-synthetic or vice versa)

The flushing process helps to get rid of deposits that have accumulated in the crankcase, in oil channels and on parts.

Self-flushing engine

Flushing, like the oil change operation, is quite simple. Any person who can hold a wrench in his hand can cope with it. But still, in order not to harm the car, you should know how to properly flush the engine without damaging its insides.

Engine flush process:

• It is necessary to drain all the old oil from the warmed-up internal combustion engine. Then flushing oil is poured into the upper neck.
• It should be about as much as it is supposed to fill in the working composition. Then the top cover is screwed on and the engine starts.
• On flushing, the motor should run for 5-10 minutes, this is enough. Then the plug in the pan is again turned off, then the flushing oil is poured out.
• If possible, it is advisable to "tilt" the car in different directions - so that there is more glass.
• The used filter is removed.
• Fresh oil is filled and a new filter is installed.

If flushing is carried out with a specialized agent poured into the car oil (gentle), then after filling it:

• Within a few days, the machine is operated in a "break-in" mode;
• The maximum draining of the oil and the removal of the filter element are carried out;
• New oil is poured and a filter is installed.

It should be remembered that in order for the car to work perfectly, it is necessary to flush the engine especially well from oil, if it does not inspire confidence, and from all contaminants.

All procedures should be performed with high-quality oil, which will subsequently be used as the main one for the operation of the motor.

Self oil change

The car is parked on a level surface. There is a pan at the bottom of the engine. It's just a container that is attached to the motor.

There is a plug at the bottom of the pallet. To drain the old oil, you need to put a container under the pan and unscrew this plug. When all the mining runs out of the hole, the cork is wrapped back.

Next stage. The cover located at the top of the engine opens. A funnel is inserted into the hole. The amount of oil that needs to be poured into the engine can be found in the instructions attached to the machine. Sometimes it is 2 liters, sometimes 3 or 3.5 liters.

When the required volume is filled, you should wait a bit, usually 5-10 minutes is enough. During this time, most of the mining will run into the pan.

Then you should pull out the probe. Finding it is easy. Often its upper extremity has the form of a ring. The probe must be wiped with a rag, re-inserted into the hole, lowering down to the limit. Then it pulls out again.

There are notches on the lower end of the probe. One of them is the minimum oil level, the second is the maximum. If the oil is filled in as much as necessary, it can be seen on the dipstick. Its upper boundary will be located near the upper notch.

How often should you flush your engine

Now about how often you should flush the engine. Through the hole in the sump, neither the flushing fluid nor the engine oil completely flows out. From 5 to 20 percent remains due to irregularities in the motor. It remains in the channels, and everything else that is present in the engine.

As a result, if 1.6 liters of oil is poured into the engine, then when it is poured out, up to 400 milliliters remains inside. If the engine is flushed, then the flush composition will become this volume. At the same time, it will simply be dirty, since it will contain old, worn-out grease.

There are various additives in engine oil. Due to their presence and combination, its quality improves. Additives provide - viscosity, prevent the formation of foam, have anti-corrosion properties, etc.

What happens when new engine oil is mixed with a quarter of the flush fluid saturated with impurities? First, good oil becomes diluted with flushing fluid.

The second - in a unit volume of the resulting mixture contains additives less than a quarter than it should be. This means that the quality of the lubricant is reduced, and engine failure becomes more likely.

From the above, it becomes clear that every time you change the oil better engine do not rinse. It is better to do this when a transition is made from summer to winter oil and vice versa, or when synthetics are changed to semi-synthetics.

In this case, it is desirable that the viscosity indicators either coincide or have a close value.

It is advisable to flush the engine after buying the car from your hands. After all, it is not known what the previous owner actually used. It should also be washed when the car is operated in difficult conditions.

Of particular note are internal combustion engines with turbines. Such units require good, clean oil. Otherwise, a breakdown may occur, and the turbine is an expensive device.

So it is better to flush engines with turbines more often. This is usually done once every two or three replacement processes.

Features of flushing the engine with various means

There are several ways to flush engines. One of them, the oldest, is the use of diesel fuel. True, it is undesirable to use it for washing imported vehicles.

If there are no other options, then the engine does not need to be started in such cases. You can simply unscrew the spark plugs and crank the crankshaft several times using the starter. Then, after a pause of 15 minutes, crank the crankshaft again, after which the diesel fuel must be poured out.

As for flushing fluids offered at retail outlets, they are always based on the usual mineral oil with added additives that wash the engine systems.

There are two types of flushing oils:

1. long action,
2. short.

The former are now rarely used. Their use suggested that the car had to be operated on such an oil for a day or two. Then it was poured out, and the oil intended for operation was occupied in the motor.

The disadvantage was that the owner of the car had to call on the service station twice, or twice deal with the engine of his car. In addition, flushing oils always perform lower than those intended for continuous operation.

So when driving with such oil, you can’t accelerate quickly, you can’t let the engine high revs, since its parts will simply well be lubricated normally.

Another minus is that alkalis are present in the flushing oil, which can corrode oil seals. After prolonged contact with such substances, the seals lose their softness and become brittle.

The best option is to use modern detergent compositions. Although the concentration of detergent additives in them is higher than in those mentioned above, in 10-15 minutes of operation they do not have time to harm rubber parts.

In addition, in such flushing oils there is always an additive that protects the seals. At the same time, it does not come into contact with the metal, on the contrary, it contributes to their laundering from deposits.

The three most popular flushing oils

Lukoil flushing oil has good qualities. It contains additives that reduce wear of parts. Of course, the cleaning properties are also quite effective.

Flushing oil, which is manufactured by the Tyumen oil company TNK-OIL, has stabilizing and dispersing properties. True, it washes the engine not so effectively.

The qualities of "Verylub", due to the large number of additives, are quite high. It reduces engine wear and cleans it well. It should be noted that this tool prevents the formation of scoring.
