How often should car oil be changed? How often do you need to change your car s oil?

In general, mineral oil.

The replacement cycle is half a year or 5000 kilometers to replace, semi-synthetic.

The oil is changed every six months or 7,500 kilometers, and it is fully synthetic.

The oil is changed every six months or 10,000 kilometers.

After the new car is bought, the front is maintained in the 4S shop, and the engine oil used for maintenance is also the so-called original engine oil. In this case, just follow along.

Car maintenance. The manual on the instructions for the interval to change the oil is sufficient.

Resemble. Japanese cars.

Most of them are 5,000 kilometers or every six months, while most cars in Europe and the United States are 7,500 kilometers or every six months. However, it is recommended that you can maintain the engine for the first time in advance, because the engine is in the first run-in period before the first maintenance, and there will be more mechanical debris in the engine. Doing maintenance early to "release" them is definitely beneficial to the engine.

If the maintenance is to replace the oil purchased by yourself, then it is necessary to distinguish the replacement interval according to the different types of oil. It is best to change the oil filter at the same time as changing the oil. The function of the oil filter is to intercept the impurities in the lower oil, and if not replaced in time, the accumulated impurities on it will cause clogging.

At worst, it will cause insufficient oil pressure, poor lubrication of mechanical parts, and in severe cases, excessive wear and tear on the engine.

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.

Many new cars can basically change the oil every 10,000 kilometers if they use synthetic engine oil in general driving conditions, and some can even drag it for 20,000 kilometers. "Ordinary driving" refers to driving on the highway a lot and rarely stopping and walking.

But 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 distance of each trip is not more than ten kilometers, this kind of driving silver burial 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 best to shorten the interval between oil changes to effectively protect the engine.

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.

If the oil is not changed for a long time, the lubrication effect of the engine oil will be reduced, and the internal parts of the engine cannot be lubricated when the engine is working, which will lead to the wear of the internal parts of the engine and shorten the service life of the engine.

It mainly depends on what type of engine oil you choose, which is generally about 5000 kilometers to change.

Different brands have different requirements, and the replacement cycle with different engine oil is not the same, there is no fixed time, it is best to ask the 4S store of the corresponding brand.

If the mileage of the car in a year is more than 10,000,000,It is recommended to change the oil twice a year, so that the car will feel more comfortable when using the accelerator, and the power of the car will be more sufficient at high speeds. The most important thing is to protect the engine and save a lot of later maintenance costs.

If the owner's car is not driven for a long time, it is recommended to choose fully synthetic engine oil, although the overall cost will be more expensive than the general special oil and semi-synthetic engine oil, but the manufacturing and refining technology of fully synthetic engine oil is high, and the cleanliness, lubrication, viscosity, and sealing performance inside the oil can meet the requirements of long-term non-open parking.

The type of engine oil and the corresponding replacement interval:

1. Mineral engine oil: 5000 kilometers or replace once every 3 months;

2. Semi-synthetic engine oil: 7500 kilometers or 6 months to replace;

3. Fully synthetic engine oil: 10,000 kilometers or once a year to replace.

General mineral engine oil: 5000 km or change every 3 months; Semi-synthetic engine oil: 7500 km or change every 6 months; Fully synthetic engine oil: change every 10,000 km or every 1 year.
