Lifetime of oil in the engine: on motorcycles or on routine. Motochas - how it is correct and why you need this parameter mileage in motoes before replacing the oil

General instructions

At the same time with maintenance Periodicity necessary Perform all operations provided for daily maintenance.

The frequency of changing engine oil and oil filter

The logical scheme proposed on the next page will help you determine maximum oil change interval and oil filter In kilometers and mile mileage or in motochas or months of operation, it seems that it will come before.

* Depending due to the one that comes first. If your vehicle is gaining many hours with a small number of mileage kilometers, then the periodization of oil change is measured by hours.

Engine oil and oil filter

Replacement

Attention! In order to avoid skin and other diseases, do not allow long and frequent contacts with spent engine oil.

In case of contamination, rinse thoroughly.

Keep in places inaccessible to children.

Environmental Protection: The accessed motor oil treatment is governed by federal and republican legislation and decisions of local authorities. For issues of collecting and disposing of spent oil, contact organizations and enterprises that have permission and having special equipment and capacities. For consultations on these issues, contact the environmental protection committees with local authorities.

NOTE: If the engine is in operation, then the frequency of changing the oil should Make up 10,000 km of mileage or 250 hours or 3 months of operation (or frequency determined for your engine according to the scheme on page 4-3).

When changing the oil, the oil filter should also be replaced in order to avoid pollution of fresh oil.

NOTE: It is necessary to drain the oil when the pollutants of its substances are suspended.

Attention! Hot oil can cause burns.

Give the engine to work until the coolant temperature reaches 60 ° C.

90-95 mm key to remove filters

Clean the mud space of the oil filter dock and remove the filter. Wipe the flushing surface of the filter.

NOTE: The annular gasket can go to the filter head. Be sure to remove it before installing the new filter.

Check and make sure that the main oil filter is used.

The six-cylinder filter is longer than the filter for the four-cylinder engine.

B \u003d Filter Size for Six Cylindrian Engine

Attention! An oil filter for a 6-cylinder engine can be used on a 4-cypindar engine, but not vice versa: the use of an oil filter for a 4-cypindra motor on a 6-cylinder engine will drive the engine.

NOTE: Fill the filters with clean engine oil before installing the engine.

Before installing the filters, apply a thin layer of engine oil onto a private surface.

Attention! Too severe tightening can damage the thread or sealing gaskets.

Install the filter in accordance with the manufacturer's instructions.

Give the engine to work on idlingTo check the leakage of oil from the filters and through the plug hole.

Stop the engine. Washed 15 minutes so that the oil is glass down, check the oil level again. If necessary, we draw oil to the top mark "H" on the level index.

Air intake system

Inspection

Inspect the air intake system in order to identify damaged hoses, weakened clamps and other faults that cause superozed air.

Eliminate malfunctions when they are detected, ensuring the tightness of the system.

Advance air cooler

Inspection

In the event of interruptions in the operation of a turbocharger or other malfunctions associated with the ingress of polluted air, it is necessary to clean the air cooler.

Remove the cooler C. vehicle, in which he enters. Next, act in accordance with the instructions of the manufacturer of the vehicle.

Inspect the air cooler for cracks, breaks and other damage.

Check the tubes, ribs and welds on the absence of breaks, chips and other damage.

The procedure for checking for tightness is set out in the section A.

Cleaning

Solvent rinse the inner cavity of the cooler in the direction opposite to the normal stream of the upgrade air. Shake the cooler and slightly knock on it with a rubber hammer to facilitate the exit of accumulated pollution. Continue flushing until it is completely removed from the cooler of all contaminants.

Attention! To clean the air cooler, caustic cleaning agents cannot be used, since they can cause damage.

After a careful flushing of the cooler with a solvent, removal of oil and contaminants, rinse it from the inside of hot soap water to remove the solvent residues. Then rinse thoroughly with clean water.

For drying the air cooler, you need to direct the stream of compressed air inside the cooler in the direction opposite to the normal flow of air. Seecess to dryness.

The order of the installation of the air cooler is set forth in the manual of the manufacturer of the vehicle.

Air cleaner

Check

The maximum allowable resistance in the air intake system for turbocharged engines is 635 mm of water column, and for engines without boosting - 510 mm of water column.

When checking the resistance in the air intake system, the engine must work with full load on the nominal values \u200b\u200bof the crankshaft.

If the resistance reaches the maximum limit, then it is necessary to replace the air purifier filter element or clean it in accordance with the manufacturer's instructions.

NOTE: Cleaning or replacing the air purifier filter element in accordance with the manufacturer's instructions.

In the presence of a dusting indicator of the air cleaner, follow its testimony.

Replace the filter element if the red indicator (2) closes the window (1).

After replacing the air purifier filter element, return indicator in the original position by pressing the button (3).

NOTE: It is impossible to work the engine "Kamminz" without a filter element of the air purifier to avoid entering the dust engine causing premature wear.

We tried to tell about why the quality of engine oil is so important, which happens to him in the depths of the engine and what factors affect its aging. It remains to tell about how these factors are associated with oil replacement intervals and how often it is necessary to change oils during the real operation.

City and highway

It must be said that the replacement of oil "in running" will almost always be non-optimal. The same mileage on the highway and in urban mode is more than a fourfold difference in the weather and a huge difference in the oil degradation. For example, with a standard replacement range of 15 thousand kilometers in traffic jams, the oil will work all 700 hours, and on the highway - even less than 200.

For the quality of oil, this more than a three-time difference is colossal, because even when working on a low load, thermal effect on the oil is very large. IN modern motors The situation is exacerbated by the high temperature of the thermostatting, poor ventilation of the crankcase and the lack of its cooling on the machine standing in the plugs, which causes a sharp decline in its resource.

On the track, the load can also be very different. At speeds up to 100-130 kilometers per hour in most machines, the load on the motor is lower than the average, the temperatures are small, and the ventilation of the crankcase works well. Powerful motors load and is minimal, which means that the load on the oil is very weak.

At speeds more, as the load on the engine increases, the load on the oil is growing. On small engagement motors with a "short" transmission, the motor and oil can already have completely disadvantaged. On more powerful motors The load will increase smaller.

Together with an increase in the load on the engine, the conditions of oil are deteriorating: the temperature of the piston increases, the flow of destructive crankcase gases is increasing. Thus, the optimal mode of operation and for oil, and for the motor are the average rate of half from the maximum and low hours of operation at idle after warming up.

When you count the hours, it turns out that the typical oil replacement interval of 15 thousand kilometers in the motochas is from 200 to 700, depending on the motion mode. Judging by the work of the regulatory mileage meters on BMW and oil replacement intervals on a technique, which is indicated in motorcycles, when typical exploitation It can be held from 200 to 400 hours for different modes exploitation permanent work In the maximum power mode.

Cases of explicit exceeding when using standard semi-synthetic oils and synthetics on a hydrocracking basis are fraught with "complications" for the engine in the form of a clocking and reducing the mobility of the piston rings.

Oddly enough, but 400 hours on typical urban speeds at 20-25 km / h are just the most 8-10 thousand mileage mileage on one serving of oil. And 400 hours at a speed of 80 km / h - this is already apparent 32 thousand kilometers unreal, although it is unlikely to strive for such an indicator.

Well, few of us boasts that they exploit cars in a country cycle with a constant speed. So what should I run mostly urban, and the engine is also forced? For example, some 1.2 TSI? Obviously, the oil needs to be changed more often.

However, not only the replacement interval depends on the ride mode. More important importance is what kind of oil is flooded in the engine.

Types of motor oils

The choice of oils in stores is very wide, if not to say huge. Some of them are not far away from Soviet mineral oils, some look in comparison with them as a spacecraft next to the cart.

First of all, you need to assimilate one important thesis: any oil consists of the basis and package of additives. The base is mineral, semi-synthetic and completely synthetic, in a variety of variations.

Semi-synthetic

Examples: ESSO ULTRON 2000.

Purely mineral oils Already almost no found, they were replaced by "semi-synthetic", which has much higher than the content of additives. Among such oils there are no long-lived, the decay products are quite strongly polluted by the motor, and the additives are kept shortly, and the viscosity changes strongly with time. But the intervals of the replacement of about 10-15 thousand kilometers them are quite forces. But a little more complicated the conditions and above the number of hours, and it would be better to cut this interval.

Synthetic hydrocracking oils

Examples: Mobil 1 New Life 0W40.

They are often considered almost as "semi-synthetic", but they are noticeably better in real exploitation. A little more expensive "base" allows you to make a jump in viscosity stability and the ability to hold the additive package. Most of "regular" oils from automakers belongs to this family. They allow in greenhouse conditions to get a mileage from replacement to replacement and 30 thousand kilometers, but in practice it is better to remember that the oils of this series are almost all small and highly dependent on the motor and gasoline.

But when runs, even 15 thousand kilometers before replacement, they turn out to be noticeably better than "mineral water": they usually have less harmful destruction products and better detergents.

But often it is not only in the hydrocracking. There are also PJSC, and Estherians, which are slightly lower. An essential feature is that the so-called Low-SAPS minor oils on this basis have a significantly reduced package of additives to minimize the amount of sulfate ash, phosphorus and sulfur, which may prolong the resource of the catalysts, but explicitly reduces the life of the motor.

Synthetic oil based on polyalphaolefins

Examples: Ravenol VPD / VDL 5W40, Liqui Moly. SYNTHOIL HIGH TECH 5W-40.

These are hits of past years and the basis of many pure racing oils. Their base is even more expensive, but they have better fluidity, and freezing temperatures are able to cope with Siberian frosts - without any additives, they can be lower than minus 60 degrees! They are almost not litto, and the products of their collapse are maximum clean and do not form climbing piston rings.

Unfortunately, these are not products of mass application, and the price of their significantly higher prices of hydrocracking synthetics, and also they have less resistant oil film and worse friction coefficient.

It is more difficult to talk about the interval of replacement, but the basis of such an oil ages very slowly. However, additive packages remain complex and still have their own service life, and mechanical pollution does not disappear. But such oils are really able to implement the Longlife replacement program without reducing the motor resource, maybe even exceed the standard interval of 400 hours.

It should be noted that low viscosity hydrocracking synthetics often contains a significant amount of PJSC, and in real exploitation, the difference between different types "Synthetics" is much less than the difference between pure bases. Malozol oils with this basis can also have a weak additive package.

Esters oils

Examples: Motul V300, Henum WRX, GPX.

Oils based on dieters and polyesters - the next step of evolution. They are even better than PJSC oils. Their dumping is lower, below and the friction coefficient. They have a very resistant oil film and excellent detergent properties of the most base. But such a basis is even more expensive, and many oils, in the title of which the word "Esttersa" is present, are not really purely oxtere, and consist of a mixture of hydrocracking products, estrices and a PJSC.

The resource before replacement in such oils is theoretically noticeably above, but by virtue of the features of the operation and the presence of a set of oils with a small package of additives, many consider such "sports" oils and not capable of working with a standard replacement interval.

In fact, the ester oils require less contamination and stabilizing additives, and test results successfully refute the theory of small resource. So do not change the estricular oil every 6 thousand kilometers, unless you want to be reinforced when they are operating on very forced tuning motors.

Butters of this type are able to "rinse" even very polluted motors, so after operation with large replacement intervals on oils with a mineral or hydrocracking basis is what the engine needs.

Now the average oil replacement interval is about 10 - 15,000 kilometers. And in other European countries, often this interval can be increased already up to 20 - 25,000! And we all accustomed to change it precisely in these frameworks, that is, through a certain kilometer. But is it right? And why on some modern machines Power units do not go long? Let's say - we produce your warranty period and continue bend. The main reason here lies in the oil, mileage and traffic jams of large cities. Let's deal with ...

Of course, if you are accustomed to buying new cars, kill the warranty 150,000 (passing through 15,000), and then take the car to the trad-in, then this material is not for you. Yet this article for someone who wants his engine to work long enough, sometimes even more stated by the manufacturer.

Marketing component

For new cars, the manufacturer dictates us to replace the oil, and this process is miraculously coincided with the next one. That is, we already get used to give a lot of money to the dealer after 15,000, something will see something will see something, here's 6000 - 10,000 rubles! Expensive, of course, expensive! Therefore, now drivers look at the interservice interval and what it is more, it is considered better. I have already said about Europe - that there is no rarely there are at 20 - 25,000 kilometers, because they have prices for work even higher.

But is it right? Of course not. Moreover, many car owners live in large cities with a bunch of plugs and thumping engines in them, it is also worth adding autoruns in the morning or put on the timer (included in time or by ambient temperature).

And here it is necessary to understand that the replacement should not take place by kilometer, but on the weather! And believe me - this is much reduces the replacement interval by kilometers, about twice (but about it a little later).

What is motorcycles?

This is a certain time interval, in this case, one hour during which your power unit worked (Motor) - from here "Moto" - "Hour". It seems everything is very simple, you can easily calculate crankshaft over this time.

So for example, at idle turnover, we have 900 - 1000 per minute, we multiply on 60 we get - 54000 - 60000 per hour rotates the crankshaft.

At higher speeds, say the track and 4000 rpm, 60 x 4000 - 240000 and so on.

The exact information on the reason how many revolutions did not count the shaft, this is especially not entirely necessary, just there is an average component, it is called Motochas, it includes both city trips with traffic jams and long standing, as well as trail accelerations.

It is clear that the shaft rotates the wear of the walls, liners, bearings, etc. But if soaked good lubricant, Let's say advanced synthetics, it can level for some time this wear, making it minimal.

Oil and its resource

But now the most interesting thing - no one will tell you at the dealer that certain lubricants You need to change through a certain number of hours, even if you have a small mileage, even very small.

WHY? Yes, because protective properties are lost, that is, there will be quite large engine wear

Now there are only three types:

• This is mineral water. By the way, now in our country almost disappeared, it should be replaced by a maximum through 150 hours (MCH). It also begins to burn your power unit through such a mileage.
• Semi-synthetic. It is worth changing it after 250mch
• Synthetics. Here is the biggest running, there are cheap options (API SJ / SL, MB 229.3, VW 502, BMW LL98) - replacement 250mch. There are more advanced (improved cracking) compositions (API SM / SN, MB 229.5, VW 502.00 / 505.00, BMW LL-01) - here is a replacement 300mch. The best purified compositions (PAO tolerances, MB 229.5 VW 502/505 / 503.01 BMW LL-01) - 350mm. Thus, in this class, lubricants ran away from 250 to 350 hours. There are still some, but they are very expensive, this is Esther, the price tag is higher than the usual synthetics at 3 - 4 times, it is simply not profitable to pour.

How to calculate motorcycles?

By the way on many expensive German foreign cars (for example, Mercedes, BMW and others), there is a special counter that believes them. And then he just shines - what you need to go to the replacement of oil, after it is resetting and you ride until the next thing. That is, here, as if there is no accurate interval, as I think it is very correct.

ON THE german cars Often there are turbines, butter flashes even faster because it goes through some nodes of the turbocharger, having gone from it warm and lubricating it, it is because of this, here the motochaes will be reduced! Even the "top" synthetic is often recommended to change after 300mch

Fashion first

However, on others modern cars There are no such meters! But there is a calculation of medium speed. And here, including logic, you can withdraw the interval.

It is done very easily and simply, you can even make a small formula.

P \u003d s * m (where p - mileage, s is the average vehicle speed with on-board computer, M - Motockats).

Ideally, after replacing the oil, we need to reset the middle speed counter and drive at least 2000 km., On small runs it will simply be not relevant. Then you have enough data to calculate everything.

On my car it is 29.5km / h, I am a synthetic composition designed for 350mch. Thus, 350 * 29.5 \u003d 10325km. Here you have a real change period, but not 15000km.

Of course, if you have a basic work outside the city, you wash on the intercity, then the average speed you will have higher. For example, my friend has 50 km / h, also pours synthetics. Here you have 300 * 50km / h \u003d 15000km.

However, residents of large megacities, such as Moscow or Peter, where in traffic jams you can stand for several hours, this indicator can be only 18 - 20 km / h, then 300 * 18 \u003d 5400km.

Method of the second

Another replacement option is fuel consumption. In the ideal case, in the mixed cycle, my car will consume 8l per 100km. If you calculate how much it will spend 15,000 - 1200 liters, it is then that I have to replace the oil! 1200 - I remember this figure.

However, with winter warm-up, in traffic jams, consumption is much more, he has 10,6 l. As a result, for 15,000, the flow is obtained - 1590l, which is 390l more !!! If you bring the formula and calculate how much mileage is needed before reaching 1200l, then approximately obtained by 11320km.

Again, away from 15000km!

As I think, change on Motocham correctly! And with an increase in the number of cars in cities, and accordingly traffic jams, we will come to this. If marketers are allowed.

Milometer Speedometer does not indicate a real state power aggregate. The degree of wear of the motor and the lubricant material is determined not by the mileage of the vehicle, but the duration of the engine operation, taking into account the operation mode of the car. Having learned to calculate how many hours passed before replacing the oil in the engine, you can change the engine fluid in time - extend the engine resource.

Car dealer indicates a period of planned, my car replacement motor fluid It must be carried out according to the regulations every 15 thousand km. Let's figure out how many hours the engine will pass when driving around the city and a motor of a similar car, the owner of which will ride mainly in the country track. Calculate, corresponds to the claimed mileage, the real period of the replacement of motor oil.

Motocats indicate the duration of the operation of the power unit at nominal turnover, the motochas is equal to one hour of normal drive operation. By performing calculations with the help of hours, you do not take into account the operating conditions of the power unit (with a loaded engine, the engine fluid is faster and requires replacement).

According to the onboard computer of my car, the average speed is 26 km / h. This is a real figure: getting to work, I have to stand in traffic jams 40 minutes, in the evening under similar conditions the car stands for 1.5 hours. With such a variable load, the mode of operation of the power unit approximates to extreme operating conditions, the drive is heated, the engine mixture is experiencing a colossal load - at high temperature changes its properties. Obviously: change the liquid will have to be remedied before the recommended run.

Relying on the facts, take for the calculation of 15 thousand km, we divide the specified mileage on the average vehicle movement speed, we get 15,000 / 26 \u003d 576 hours. Here you take into account the time of staying in traffic jams, plus the engine warming in the winter (the on-board componrate begins to count from the moment of starting the drive).

According to the calculations, we obtain the value, bring them in Table 1

Table 1. Dependence between motorcycles, speed and mileage

The average speed in the city is approached by 30 km / h, a similar car on the country track will drive a distance of 3 more, on the highway the car moves 70 km / h. Both motor will make the same amount of work. The speedometer of the first car will show the mileage much less than the second car. It is worth thinking how real is the digit specified by the dealer to replace the lubricant mixture.

Video about changing engine oil depending on the events passed

Operating conditions

Under the ideal conditions, the car in the city develops a speed of 40 km / h, we get 15,000 / 40 \u003d 375 hours. For the country track, we take - 80 km / h, we expect 15,000 / 80 \u003d 188 hours.

Compare the resulting experimental path 576 with the calculated 375, we conclude: the engine works in heavy conditions operation, to increase its resource you need to change the machine 2 times more often. Many people do not know: the replacement of the engine fluid is regulated, is:

• 250 hours for ACEA E2, API CF, CF-4, CG4;
• 400 - VDS, ACEA E3;
• 600 - for VDS-2.

In the service book it is indicated - under the difficult conditions of operation, the replacement of the car occurs every 8 thousand km of mileage. These conditions include:

• there is a significant amount of dust in the air;
• continuous ride at low speed;
• movement of the vehicle in mountain, hilly terrain;
• high temperatures overboard cars;
• use of fuel of dubious quality;
• frequent change of filling stations;
• when towing the trailer;
• fully loaded trunk.

If there is no possibility to conduct the specified calculation, the masters are recommended to rely on fuel consumption. For example, the car must spend 9 liters of gasoline or Dt per 100 km around the city, according to the regulations, for 15 thousand km of mileage will be 1,350 liters - (15000/100) * 9, real flow It is 11 liters per 100 km, at 15 thousand km it will be 1650 liters. Change fluids is necessary at a volume of 1350 liters. This is the relative method.

Responding to the question: "How many hours should the weather be passed before replacing the engine mixture in the engine?", Consider:

1. Type of power unit. Inside diesel engines The temperature is significantly higher than in gasoline drives. Lubricant material is exposed to large loads.
2. Motor loading, with an increase in load, the resource of the machine is reduced.
3. The car rides the country track or in the city. On the track, the motor wearhes slower: it works for a long time with the same load.

Change the mixture according to the mercasses passed, do not conduct a planned replacement of fluid on the mileage of the machine. Use certified products that responds. technical characteristics Motor, apply the machine to the recommendations of the vehicle manufacturer.

One of the main conditions that provide the normal operation of your engine is right choice and timely replacement Motor oil. This substance is responsible for the resource of the engine and its correct operation. Wrong choice of oil type or its processing can carry a potential threat to the operability of your vehicle.

Olov must be changed in a timely and systematically - it knows every motorist.

- How often? - you ask.

- You need to look at the regulations! - Every motorist will answer.

But in this answer there is a particle of inaccuracies. Have you ever wondered: why exactly such a regulation? Yes because car manufacturer Tried hundreds of such engines and exposed them to different loads. For the rules, only one indicator is indicated. Therefore, only one generalized statistical indicator takes for its formation. Traditionally, it is 10-15 thousand kilometers.

Will there be the same regulations for replacement of oil in the engine for fans of fast and calm ride, and for urban and country pace? The answer is unequivocal - of course not!

The operation mode significantly affects the state of the motor olive, and therefore on the regulation of its replacement.

Specificity of car operation

Logical conclusion is that the regulations for "urban" and "intercity" cars are different. We are talking about urban traffic jams when the oil and engine elements are exposed to high temperatures, Natural ventilation Carter is minimal and at the same time runs minimized. In this case, 100 km of the path in traffic and 100 km on the track are two different operational indicators for the engine and different loads.

The difference in operating conditions in traffic jams and when driving on the highway almost three times. Therefore, it is also necessary to take into account the time replacement regulations. Some manufacturers additionally indicate the approximate regulations in the weather.

Tubes - the main factor for reducing the oil change regulations

The most optimal operating conditions of the engine is to ride on the highway at a speed of 110-120 km an hour. In this case, the engine does not overheat, works for a third of its power (for the predominant most engines), and the ventilation of the crankcase is just excellent. However, not all 100% of engines are suitable for such a characteristic.

Lovers rapid driving (also increased engine loads) and those who are forced to stand in traffic jams it is important to remember that under such conditions of operation of the vehicle, the regulation is significantly reduced.

Optimal conditions for engineering in the engine: medium speed mode And the short engine warming (this does not mean that at the first motor factory you need to go right away).

If we translate the standard oil replacement regulation of 15 thousand to hours, and compare it with the features of urban and country ride, then the following indicators are obtained:

• For traffic jams and slow urban ride to 25 km / h (which meets very often) - the replacement regulations of 7-10 thousand km.
• For a country ride at a speed of more than 90 km / h, the development resource may increase to 20 or more than a thousand km. However, it is not recommended to "rewrite" the oil in the engine even in conditions of such a measured country ride.

That is why every motorist and the owner of the car must be remembered that the service regulation is just a weighted average indicator that does not include your individual component: the nature of the ride, the mileage of the car, the conditions of operation, the size of the city, and so on.

That is why it is necessary to fully monitor not only behind the level, but also for the condition (color, consistency) of the engine oil. If necessary, you can contact more experienced colleagues for professional summary. 10 or 15 thousand kilometers is not a final sentence to replace, everything is much individual.

It is smoothly as much as the manner and the nature of the ride, the runs and features of the city are, smoothly so and affects the right choice of engine oil. Natural, synthetic and semi-synthetic oils - All of them have their own features of operation and advantages. When choosing, you can be guided by the recommendations of the manufacturer, advice of professionals or personal experience. The choice must be conscious and fit the method of operation of your vehicle. Remember that the choice of oil is the key to the engine performance, its resource and technical and performance indicators.

Tomorrow we will look at features different species Motor Olives. After reading these articles, you will be able to select the appropriate type of engine oil and follow your own, more correct, replacement regulation.

In the comments, write how often you change motor oil And what operating conditions of your car.

Good Friday and smooth roads!
