How often should the car change the oil and how often should the car change the oil

Generally speaking, the first oil of the new car is changed within 2000 kilometers, and then every 5000 kilometers to do ordinary maintenance, maintenance of the oil and oil filter must be changed, the air filter is recommended to be replaced once in 5000 10000 kilometers, I change every 5000 kilometers, many people do not pay attention to the air filter, do not change for a long time, just take it out and beat it, in fact, this is to save a small amount of money and spend a lot of money, the air filter element is not often changed on the engine life and fuel consumption has a great impact. As for the gasoline filter, it can be changed infrequently, generally every 50,000 kilometers or when the winter is almost over every year (it is recommended to replace it at 120,000 kilometers for high-end cars). As for the gearbox oil, the manufacturer's standard is generally 20,000 kilometers to change, even if it is recommended to change it once a year, about 50,000 kilometers.

The other is about 50,000 kilometers to replace the spark plug, 680,000 kilometers to change the timing belt, and about 100,000 kilometers to do a major maintenance.

Supplement: 1 20,000 kilometers of tires reversed, front and rear wheel replacement, 50,000 kilometers of four-wheel alignment. The life of a tire is generally 8.1 million kilometers.

No matter which brand of engine oil, there are specifications and models. The specifications of the engine oil are mainly: SF type: suitable for economy cars and minivans; SJ type: about 100,000 mid-range cars; SL type: Audi, BMW, Mercedes-Benz and other high-end cars.

The correct time to change the car oil.

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

Engine oil, that is, engine lubricating oil, can lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the "blood" of automobiles. Engine oil is made up of two parts: base oil and additives.

Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil.

How often to change the car oil.

It depends on the type of oil to be used in the vehicle.

Generally, there are 3 types of engine oils, fully synthetic, semi-synthetic, and mineral engine oils.

Generally, fully synthetic engine oil is changed every 10,000 km or 1 year.

Generally, semi-synthetic engine oil is changed every 7500 km or 7-8 months.

The general mineral oil is changed every 5000 km or 6 months.

It is recommended to change once every 5,000 kilometers for bad driving habits, and once for 8,000 kilometers for good driving habits.

Generally, the oil should be changed every six months. 1. The quality of the engine oil is not the same, the road conditions are different, and the replacement time is changed; 2. The service life of fully synthetic engine oil is the longest, and it can generally be replaced between 10,000 kilometers if fully synthetic is used; 3. Semi-synthetic engine oil can be replaced at 8000 kilometers. Ordinary mineral oil is better in advance.

According to the quality of China's oil products, it is more appropriate to change the oil at an interval of 8,000 kilometers. If you drive on congested roads for a long time, the engine will work in a harsh and chaotic environment, and the oil cleaning will be intensified, which may shorten the oil change interval. Remember to change the machine filter as well as changing the oil.

Poor quality machine filters can affect the quality of your oil. In the case of a high-temperature environment, the internal combustion engine is constantly high-fiber, and the repetitive mechanical friction movement oil plays a role in cooling, lubricating and cleaning in this project. After a long time, there will be more impurities in the oil, and the performance will also decrease.

Engine oil can lubricate the engine, reduce wear, prevent rust and corrosion, and is known as the "blood" of the car. Oil change is an important part of car maintenance and is crucial to the operation and longevity of the car. The timing of the oil change is also important.

Changing the oil too soon is a waste of money. It's too late to change it, it's not good for the car. So how often should you change the oil?

Is "5000 km oil change" the standard answer?

When it comes to oil change intervals, many car owners will "once every 5000 kilometers". Is this true?

In fact, the oil change interval is affected by many factors, not only the mileage, but also the type and quality of the oil, driving habits, road conditions, season, vehicle age, etc. Generally speaking, the oil change interval specified in the car manual is the longest, and different situations should be considered in the actual use process.

Look at the driving situation.

If you don't use your car as often, you can decide whether to change it based on the mileage and the shelf life of the oil.

It's not the same if you commute by car and are often stuck in traffic.

In the congested road conditions of the city, the car frequently stops and starts, which puts a lot of pressure on the engine oil. When the performance of the engine oil exceeds the critical value, the engine cannot be effectively protected. In this case, the replacement cycle should be shortened.

If the owner has bad driving habits such as long-term acceleration and frequent sudden braking, it will accelerate the wear and tear of various parts in the car, so the replacement cycle should be shortened on the premise of oil mileage.

If you drive in dusty areas or low-temperature areas for a long time, the oil change interval should also be shortened. On the contrary, if the environment is clean and the air is clean, the oil change interval can be appropriately extended. In areas with poor road conditions, oil change intervals should also be shortened.

Take a look at the old and new cars.

If you just bought a new car, its parts need to be run in, resulting in increased friction, and the new engine can only reach the lowest fuel consumption after running for a while. At this time, the oil is used quickly, and the frequency of replacement is naturally high.

If it is an old car that has been driven for three or four years, the friction between the parts is not large, and the lubrication effect of the oil is higher at this time. As long as the engine is working properly and the environment is good, an oil change interval of 5000 km is completely feasible.

Look at the type of oil.

From the perspective of time, mineral oil generally comes into contact with air for about 3 months before it begins to oxidize and its function declines. Half of the synthetic oil is six months, and the whole of the synthetic oil can be one year.

In terms of mileage, mineral oil generally begins to decline at 5000 km. Half of the synthetic engine oil is generally 7,500 kilometers, and all synthetic engine oil is about 10,000 kilometers.

Therefore, specific problems cannot be generalized for specific analysis. If you still have doubts about when to change the oil, you can buy the oil test strip, which is not expensive, so that you can more clearly and conveniently judge whether you need to change the oil!

How often Lu Yubi changes the oil depends on what road you usually drive and what kind of oil you use. If you drive on ordinary city roads and use all the synthetic oil, you need to change the oil every 8,000 to 10,000 km.

Motorists are advised to choose a fully synthetic motor oil when buying a motor oil. Although this oil is more expensive, it has better lubricating properties and a longer service life.

There are three types of engine oils, fully synthetic engine oil, semi-synthetic engine oil, and mineral engine oil.

Synthetic motor oil base oils are synthetic, and the molecular size and shape of this oil are almost the same, so this oil has better lubricating properties and a longer service life.

The base oil of mineral oil is extracted from petroleum. The molecular size and shape of this oil are irregular. The lubricating properties of this oil are average, and the service life is not very long.

The oil needs to be changed regularly. If it is not changed for a long time, the oil will become thinner, affecting the lubricating performance of the oil. If the oil is left in the engine pan for a long time, the oil will deteriorate with oxygen depletion, which will also reduce the lubricating performance of the oil.

Replace the oil filter element with each oil change. The oil filter destroys the oil and keeps it clean.

When buying an oil filter, you also need to choose a big brand**.
