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

It is Difficult to overestimate the importance of oil in the engine. Thanks to him, the motor can work properly for a long time. It is known that the lubricating fluid should be changed regularly. Perform this procedure after a certain mileage. Why change the oil in the engine and how many kilometres to do so, we consider in this article.

What happens to oil when working

If you are working the grease in the motor is polluted with wastes from fuel combustion, dust and other debris, among which includes the products of combustion of the liquid. In addition, the chemical reaction is oxidation and oil condensation can form. As a result, it becomes aggressive for the elements of the motor.

Over time the lubrication greatly thickens, loses its beneficial cleaning properties, as with continued work incoming additives in the engine oil was dissolved waste from the combustion of fuel, but because it washes off like soap. The inside engine is nothing to be flushed, and it arises Nagar. The question arises: how to change the oil in the engine? Five thousand kilometers, ten, twenty or thirty?

Accurate universal mileage just isn't there, since this value is affected by many factors. First and foremost, of course, focus on those recommendations that is specified in the user manual of the vehicle manufacturer. But besides these there are other indicators. After reviewing them, you can precisely predict the right intervals how to change oil in the engine.

Operation and motor design

Engines have a Different characteristic modes of operation. The budget could not bear the hard drive. Therefore, if a car constantly squeeze all possible, the grease is consumed much faster, and therefore the wear will increase, and waste will be much more. More powerful diesel cars go at high loads. Wear have high. Therefore, the oil for diesel engines should have a large number of additives. But whatever the number, the burnt fluid will be washed with their own additives and to quickly come into disrepair. It is necessary to understand and take into account, thinking about when to change the engine oil in the engine.

City — track

Interestingly, if the predominant operation of the vehicle in oil should be changed more often than with constant driving on the highway.

This Happens because on the highway you can drive safely, without interruption and with a certain speed. At the same time, the city is constantly lit traffic lights, traffic jams, where you stand with the engine. Therefore, in such circumstances it would be better to not count mileage and engine hours. It is quite possible to read a hundred kilometers on the highway for an hour, while twenty miles away in the city — after a full eight hours.

It Turns out that the city mileage for the motor is at partial load, therefore, the oil for diesel engines or petrol will fit longer. But when you constantly have to accelerate, then slow down, it affects the gasoline consumption, and lifetime lubrication. At the same time for hours idle in traffic jams and at traffic lights are not included in the mileage by the manufacturer.

Loading

The car can be driven in a relaxed mode and in the boot, e.g. with a trailer. The additional load is acquired also when riding uphill. All this, naturally, affects the motor and oil. At larger strain the oil need to be changed more often.

The Level of load affects the fuel consumption. Therefore, many experts believe that the replacement of the lubricating fluid should be carried out when binding of consumed gasoline. Ideally will also have ten liters of fuel per hundred kilometers. Therefore, the required mileage for oil change ten thousand kilometers, will take one thousand liters of gasoline. Based on this, you can calculate how many change the oil in the engine. That is, if you spent one thousand liters of gasoline can be replaced. Because the mileage will be only when the car is going and consumes gasoline. And the latter always takes longer because of delays in traffic jams, at traffic lights and other stops with the engine running.

Operating temperature

Ideal for lubrication is considered to be ninety degrees. Examples include engines «Porsche» and «BMW». On the first working temperature was and continues to be of ninety degrees. If this car is considered one of the most reliable at present. On the other hand, “BMW” once attributed to one of the most reliable. Nowadays, however, the engine began to wear out much earlier. Many of them don't even have time to run the first hundred thousand kilometers.

And it happened for a simple reason: in the car «Porsche» continue to hold the same operating temperature that it was before. At the same time, “BMW” with each new engine model, it increased. Made in the company as a result of the reverse results.It is clear that on the old “BMW” the resource will be more than new.

Warm up motor

Regarding temperature is interesting and an indicator such as warming up the engine. If the vehicle travels more on short distances and no time to warm up to the required temperature, then surely it would reflect badly on the engine. While he stood, it formed the condensate. This is especially characteristic for the cold time of year. To all the moisture has time to evaporate prior to mixing with the oil, the motor must warm up and pass great distances. But simple winter condensation is a large number. Therefore, in such cases it is better to go to the mechanic and change the oil, not even thinking through how to change the oil in the engine.

Quality

Trends in the world such that in all of the processes trying to minimize the damage to the environment. That is true exploitation of oil. The timing of the increase and the producers themselves, adapting to these standards. Therefore, synthetic oils continue to develop, inventing new solutions in order to extend the mileage by adding all kinds of additives in the engine oil. Such lubricants are really able to work out even thirty thousand kilometers.

At the same time must take into account all the above factors. For example, this applies to hard drive or, on the contrary, frequent many hours idling in traffic jams. Therefore, replacement should be done before the specified date, mileage.

At the same time, we must not forget that the manufacturer is beneficial to the car fell into disrepair shortly after the end-of-life. Because such technology has a great run and developed.

Transparency

Suppose that we are approaching the time when it is possible and necessary to replace oil. How to test this actually? One way is through visual assessment. This comparison is made with fresh, not used oil.

This oil should not be cold. Because its viscosity is different from hot. The car slid for a few minutes and then turn off and check the dipstick. At the sight of shade, Coca Cola replacement is required immediately.

However, if you quickly darkened with new oil, it has not said clearly about his poor quality. It just may enter the special detergent additives. So for a more accurate diagnosis one visual assessment is not enough.

Drain

If the set of parameters is still one conclusion - to be replaced, then make it as follows. Raise the car in the bodyshop or driven on a rack and drained the used oil. To do this:

• Is tube maslowska and relax;
• Under the location of the drain is enclosed by the large capacity of five liters and the pan;
• Drain is carried out as soon as the butter cools;
• Gasket has to be changed.

Replacement grease

Differently is determined by the amount you need. The engine oil change, primarily focusing on the recommendations of the manufacturer. And if manual, where this information is listed on his hands, you can find the specific model on the manufacturer's website. The average passenger car requires from three and a half to five and a half liters. For example, engine oil "Jetta" poured into a volume of 3.6 liters, and “Tiguan” four liters.

To replace the oil, special knowledge is not necessary. Just be very careful not to burn yourself, and not get dirty. Oil can ignite when heated, so better to use a funnel. Cold grease moving slower, so you should wait until it would to the pan, and then check your dipstick.

Transfused or Underfilled oil no good for the motor does not promise. For example, it may be the engine oil. The cause of the incident, of course, lies in the overabundance composition. However, the consequences for motor will eventually be very sad. Therefore this situation to rest is impossible, and you should immediately get rid of excess. There are a couple of ways, and at least one of them can easily be made yourself using medical syringes and tubes for blood transfusions.

The Lack of lubricating fluid even more disastrous for the engine, since the rubbing side by side parts without oil will quickly become worthless, thus the service life of the whole motor will be significantly reduced.

Check the level and condition of oil in the engine. When caring for it will work properly for a long time.
