How much to change the oil in the engine? Additives in engine oil

It is difficult to overestimate the importance of oil in the engine. It is thanks to him that the motor is able to work properly for a long time. It is known that the lubricating fluid must regularly change. Produce this procedure through a certain mileage. Why change the oil in the engine and how many kilometers to do it, we will consider in this article.

What happens to the oil when working?

In operation, the lubricant in the engine is contaminated with waste from fuel combustion, dust and other debris, including combustion products of the liquid. In addition, as a result of the chemical reaction, oxidation takes place, and condensation can form in the oil. As a result, it becomes more aggressive for the elements of the motor.

Over time, the lubricant becomes much thicker, loses its useful detergent properties, because during constant operation, the incoming additives in the engine oil dissolve the waste from the combustion of the fuel, and therefore it is washed off like soap. The engine can not be washed from the inside, and there is a build-up on it. The question arises: how much to change the oil in the engine? Five thousand kilometers, ten, twenty or thirty?

An exact universal kilometer does not exist, since many factors influence this value. First of all, of course, they are guided by those recommendations, which are specified in the vehicle's operating manual by the manufacturer. But besides them there are other indicators. Having studied them, you can more accurately guess the necessary intervals, after how much to change the oil in the engine.

Operation and design of the motor

Different engines have their own modes of operation. Budget options will not take a tough ride. Therefore, if such a car is constantly squeezed everything possible, then the lubricant will be consumed much faster, so that wear will increase, and the burnout will be many times greater. More powerful diesel cars drive at higher loads. Wear of details is high. Therefore, the oil for diesel engines should have more additives. But no matter how many of them are, the burnt liquid will be washed with its own additives and quickly deteriorate. It is necessary to understand and consider, thinking about when to change engine engine oil.

The replacement will normally be once every ten thousand kilometers. And if the ride is still active, then two and three thousand less.

City - highway

It is interesting that with the primary use of the car in the city, the oil needs to be changed more often than with constant driving on the road.

This is because on the road you can go quietly, without stops and at a certain speed. At the same time, traffic lights are constantly lighting in the city, traffic jams are formed where it is necessary to stand with the engine running. Therefore, in such conditions it would be more correct to consider not the mileage, but the engine hours. After all it is quite possible to read off hundred kilometers on a line for an hour, while twenty kilometers around the city - for all eight hours.

It turns out that in the countryside, the mileage for the engine runs in a more gentle mode, so oil for diesel engines or gasoline will be suitable for longer. But when you constantly have to accelerate, then slow down, this greatly affects the consumption of gasoline, and the working life of the lubricant. At the same time, many hours of idle speed in traffic jams and traffic lights are not accounted for in the run by the manufacturer.

Loads

In the car you can drive in a quiet mode, and in a bootable state, for example with a trailer. Additional load is also acquired when driving uphill. All this, of course, affects the engine and oil. With a larger load, you need to change the oil more often.

The load level also affects the fuel consumption. Therefore, many experts believe that the replacement of the lubricating fluid must be carried out when binding to the used gasoline. Ideally, you get ten liters of fuel per hundred kilometers. Therefore, with the required mileage to replace the oil in ten thousand kilometers will require a thousand liters of gasoline. Proceeding from this, it is possible to count, how many to change oil in the engine. That is, with a thousand liters of gasoline consumed, a replacement can be made. After all, the mileage will be the same only when the car goes and consumes gasoline. And the last one always leaves more because of idle time in traffic jams, traffic lights and other stops when the engine is running.

Working temperature

Ideal for lubrication is ninety degrees. An example can serve as engines "Porsche" and "BMW." At the first, the operating temperature was and still remains ninety degrees. In this case, the car is considered one of the most reliable at the moment. On the other hand, "BMW" was once also considered one of the most reliable. However, these days the engine began to wear out much earlier. Many of them do not even have time to run the first hundred thousand kilometers.

And it happened for a simple reason: in cars "Porsche" continue to keep the same operating temperature as it was before. At the same time in "BMW" with each new model of the engine it rises. Achieved in the company as a result of the opposite results. It is clear that the old "BMW" resource will be more than new.

Motor warm-up

Regarding the temperature is also interesting and such an indicator as warming up the engine. If the car rides more at short distances and does not have time to warm up to the required temperature, then certainly this will have a bad effect on the engine. While it is standing, condensate forms in it. This is especially true for the cold season. To ensure that all moisture has evaporated before mixing with oil, the engine must be constantly warmed up and pass a considerable distance. But with a simple winter condensate formed a large number. Therefore, in such cases it is better to immediately go to the technical center and change the oil, without even thinking about how much to change the oil in the engine.

Quality

Trends in the world are such that in all produced processes try to minimize the damage to the environment. Including it touched and the exploitation of oil. Timing is also increased by the manufacturers themselves, adjusting to these norms. Therefore, synthetic oils continue to develop, inventing all new solutions, in order to increase the mileage, adding all kinds of additives to the engine oil. And such lubricants are really capable of working even thirty thousand kilometers.

At the same time, all the above factors must be taken into account. For example, this applies to hard driving or, conversely, frequent hours of idle time in traffic jams. Therefore, the replacement should be made before the specified mileage.

At the same time, we should not forget that it is advantageous to the manufacturer that the car should become unusable soon after the end of its useful life. Because such technology is a large run and are being developed.

Transparency

Suppose that the time is approaching when it is possible and necessary to change the oil. How to test this in fact? One way is visual assessment. This comparison is made with fresh, untreated oil.

This oil should not be cold. Because its viscosity is different from hot. The car is turned on for a few minutes, and then turned off and checked with a feeler gauge. At the sight of a shade of Coca-Cola, replacement is required immediately.

However, if a new oil has quickly darkened, this does not yet clearly indicate its poor quality. It simply can include special detergent additives. Therefore, for a more accurate diagnosis, one visual assessment is not enough.

Draining

If there is only one output for the set of parameters - a replacement is required, then it is produced as follows. The machine is lifted in the technical center or driven to the overpass and the waste oil is drained. For this:

• The oil stopper plug is loosened;
• Under the place of drain is put a large capacity of five liters and a pallet;
• The drain is carried out as the oil cools;
• The sealant should be changed.

Grease change

Its required quantity is determined in different ways. Oil in the engine is changed, primarily based on the recommendations of the manufacturer. And if the operating manuals, where this information is indicated, are not on hand, you can find it on a specific model on the manufacturer's website. On average, a car is required from three and a half to five and a half liters. For example, oil in the engine "Volkswagen Jetta" is filled in volume of 3,6 liters, and in "Tiguan" - four liters.

In order to replace the oil, special knowledge is not needed. You just have to be extremely careful not to get burned and not get dirty. The oil can catch fire when heated, so it's best to use a funnel specifically. Cold lubrication moves slower, so it is worth waiting for it to reach the tray, and then check the level of the probe.

Unsuitable or poured oil does not bode well for the motor. For example, there may be an engine in oil. The reason for what happened, of course, is hidden in an overabundance of the composition. In this case, the consequences for the motor will in time be very sad. Therefore, it is impossible to leave such a situation unchanged, and you should immediately get rid of surpluses. There are several ways for this, and at least one of them can be easily carried out by itself using a medical syringe and a blood transfusion tube.

Lack of lubricating fluid is even more destructive for the engine, since rubbing the side parts without oil very quickly become unusable, thereby the resource of the entire motor will be significantly reduced.

Observe the level and condition of the engine oil. With a careful attitude, it will work properly and for a long time.
