How often should I change my oil? How often does it take to change the oil?

This should be determined according to the frequency of use of the engine, the general private car can be replaced in accordance with the provisions of the maintenance manual, ordinary mineral oil is generally 5000 kilometers or half a year, fully synthetic engine oil can be changed 10000 kilometers, in addition to according to your road conditions, you can change in advance, frequent oil changes are good for the engine, but do not need to be too frequent, otherwise it will cause waste.

How to determine the oil replacement time depends on what type of engine oil is used.

How often to change the car oil.

Engine oil is an important part of the engine Runhua, and the engine can work and burn normally under the normal state of engine oil.

Therefore, during normal use, you should ensure that the viscosity of the engine oil is normal, and it cannot enter water, fuel, and mechanical debris.

For general engines, naturally aspirated engines are generally about 7,000 to 10,000 kilometers. The supercharged engine is generally about 5000 km.

For specific situations, you can refer to the vehicle maintenance manual, and the suggestions in the manual are generally the most reasonable recommended values made by the main engine factory according to the technical level of its own engine.

Pay attention to the three major elements of oil change, and there are some detailed precautions, which are detailed as follows:

1. When should I change the oil?

In the general driving situation of a new car, if synthetic engine oil is used, the oil can basically be changed every 10,000 kilometers, and some can even be dragged up to 20,000 kilometers. According to auto repair professionals, "general driving" refers to driving on the highway a lot and rarely stopping and walking. However, if you often drive in the city, there are traffic lights when you go to **, you will be stuck in traffic at every turn, and most of the distances of each trip are not more than ten kilometers, this kind of driving method belongs to "attritional driving".

In the case of "weary driving", the engine wears a lot and the oil demands are high. Therefore, it is advisable to shorten the interval between oil changes in order to effectively protect the engine.

Tips: It is usually difficult to decide whether the engine oil should be changed by the naked eye or touch, but after long-term use, the oil will accumulate a large number of impurities, if you do not replace the new oil in time, these impurities will wear out the engine for a long time and shorten the life of the car.

Second, how to choose engine oil.

Choosing a good engine oil can make your car more durable and powerful. A good engine oil, especially a fully synthetic one, can not only protect the engine and reduce the number of oil changes, but also save on gasoline costs. Therefore, it** is twice as expensive as regular oil, making it the best choice for many car owners.

In general, the following four elements should be paid attention to when choosing engine oil:

1. The selection of engine oil should be selected according to the requirements of the engine, and it is not necessary to use too high-grade engine oil on the engine with lower requirements, nor can the lower-grade engine oil be used on the engine with higher requirements.

2. Multi-grade oil should be selected as much as possible, because multi-grade oil has a good protective effect on the engine due to its saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

3. The quality of some domestic brand-name engine oil is quite good, and it is much lower than that of similar imported products, so it can be used with confidence, and there is no need to blindly pursue "foreign oil".

4. If the engine is in good condition and the temperature is low in season, the oil with low viscosity should be used as much as possible to make the oil circuit smooth. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear.

3. The amount of oil should be slightly lower than the scale on the oil dipstick, and it should not be overfilled.

Engine oil is extremely important for the movement of the engine, as it is responsible for lubrication and heat dissipation. Therefore, at any time, there should never be a shortage of oil for the engine. But adding too much (exceeding the upper limit of the ruler) has bad consequences.

Too much oil will increase the rotational resistance of the crankshaft, reduce the output power of the engine, and the excess oil will enter the combustion chamber to participate in combustion, causing the vehicle to burn oil, blue smoke, and increase fuel consumption.

Different types of engine oil, the frequency of change is different. It is recommended to change mineral oil every 5,000 km or half a year, semi-synthetic oil every 7,500 km or 8 months, and fully synthetic oil every 10,000 km or a year. Like Wells, it uses a fully synthetic engine oil, which has a low frequency of oil changes, which is particularly worry-free.

The correct time to change the car oil.

Engine oil can be divided into mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil, if the mineral engine oil is used, it is generally replaced once every half a year or about 5000 kilometers; If you use semi-synthetic engine oil, change it once every 7-8 months or about 7500 kilometers; If you use a fully synthetic engine oil, you can change it after driving for 1 year or about 10,000 kilometers. The owner can judge whether it is time to change the engine oil from the following methods: 1. Check the oil ruler:

The easiest way to do this is to look directly at the oil gauge, and if the oil level is below the minimum limit, you should change the oil to a new one. 2. Oil emulsification: When the oil is emulsified, foaming, blackening, impurities or viscosity is reduced, the oil should be replaced in time.

3. Engine noise: The noise in the cylinder can be heard, which may be the debris of mechanical friction entering the oil pan, and being continuously brought to the cylinder with the oil transmission to the piston, making a collision sound. At this time, there are many impurities in the oil, so the oil should be replaced, and the oil pan should be cleaned if necessary.

4. High fuel consumption: serious engine shake and other phenomena should attract the attention of car owners. 5. Abnormal engine temperature

It could also be a lack of oil causing the cooling system to malfunction. 6. There is a harsh sound when the engine is running: at this time, it may be because the viscosity of the oil is not enough, which leads to the decline of the lubrication effect, and the sealing ring of the piston directly scrapes against the cylinder wall, which is the so-called "pulling cylinder", which will lead to the scrapping of the engine when it is serious.

Mineral engine oil generally begins to oxidize after about 3 months of exposure to the air, and the function declines, if you don't drive after 3 months after changing the oil, you should change the engine oil again, and the synthetic engine oil is about half a year or 9 months. If you drive, domestic road conditions, mineral oil leakage generally begins to decay after 5000 kilometers.

Semi-synthetic generally starts at 7,500 km; The engine runs in different environments, the running time and the strength of the running straps are different, in fact, the car itself does not have a bad grip to judge the state of the oil, all car companies will use mileage estimation when setting the oil change interval.

The oil change interval is determined according to the type of oilThe recommended replacement interval for fully synthetic engine oil is one year or 10,000 kilometers. Because the performance of fully synthetic engine oil is relatively good and the antioxidant capacity is strong, the use cycle can be longer.

Semi-synthetic motor oil has a change interval of 8 months or 7,500 km, while mineral oil has a service life of only six months or 5,000 km. It should be noted that this cycle is to take into account both time and kilometers, as long as one of the two meets the deadline, it needs to be replaced, and it cannot wait until it is reached at the same time.

Common sense about motor oil.

The performance of motor oil is not only about oxidation resistance, but also in many other aspects. For example, cooling ability, smoothness, anti-freeze performance, cleaning ability, etc., these properties of synthetic engine oil is also much better than modified oak mineral oil. It is because of these good characteristics that synthetic motor oil can have a longer replacement interval and protection.

As for semi-synthetic engine oil, because there is a certain proportion of mineral oil in it, the performance is weaker than that of fully synthetic engine oil, so the replacement cycle will be shorter, but it is also cheaper and economical.

The above nuclear content refers to Phoenix.com - how often is the fully synthetic engine oil replaced? Why?

There is no fixed cycle for the oil replacement cycle, which is related to many factors such as the car environment, habits, oil types, etc., without considering the influence of factors such as environment and habits, if you want to change the cycle for a long time, you can use fully synthetic engine oil.

Normally, mineral engine oil needs to be replaced for about 5,000 kilometers, semi-synthetic engine oil about 8,000 kilometers, and fully synthetic engine oil about 10,000 kilometers. It is important to note that motor oil also has a shelf life, and it is generally not recommended to change the cycle for more than 18 months. So you can't run thousands of kilometers a year, and you don't necessarily have to use synthetic motor oil.

He won't increase the power of the engine, because no matter what the oil, it only cools and lubricates, and cannot change the engine power.
