Which oils are the five oils in the five oils and four filters for automobiles? How often to change them respectively? Do not understand to see

Many car owners and friends have no concept of the replacement cycle of various fluids on the car, such as engine oil and transmission oil. Most car owners think that it is enough to add it when it is used up. In fact, these oils will deteriorate. If the replacement is not timely enough, it will have a certain impact on the car and even cause irreparable damage. Today I will talk to you about the car "five oil" replacement cycle.

1. Motor oil

The first thing that comes to mind is engine oil. The engine is the heart of the car. There are many metal surfaces in the engine that rub against each other. These parts move fast, poor environment, working temperature up to 400 ° C to 600 ° C, in such poor working conditions, only qualified lubricants can reduce the wear and tear of engine parts.

Different types of oils have different replacement intervals:

Mineral oil: 5000 kilometers or 6 months

Semi-synthetic oil: 7500 kilometers or 6 months

Full synthetic oil: 10,000 kilometers or 12 months

2. Brake fluid

Brake fluid, also known as brake fluid, is a functional fluid that transmits pressure in the vehicle braking system to enable the braking system on the wheels to realize the braking effect. It has four functions: energy transfer, heat dissipation, anti-corrosion and lubrication. No matter what brand of car, brake fluid after a long time of use, will be because of the total pump inside the bowl and piston wear caused by brake fluid turbidity, which in turn affects the braking effect. In addition, the brake fluid will also absorb moisture in the air, brake fluid water more boiling point reduction, long time braking is easy to produce air resistance, resulting in brake failure. Therefore, you need to replace the brake fluid in a timely manner, generally recommended replacement cycle for 2 years or 40,000 kilometers.

3. Antifreeze

Antifreeze is an important heat conductor for vehicles. It prevents the cooling system from rising in winter due to freezing, while in summer it prevents the water tank from boiling, so it is as important as engine oil. Antifreeze has a service life of 3-5 years or 100,000 kilometers. Check the level every time you do maintenance during the validity period and add as appropriate, and replace the antifreeze when the validity period is almost over.

4. Transmission Fluid

Transmission fluid is a clean fluid to keep the gear system clean, it can ensure the normal work of the transmission and prolong the service life of the transmission device. According to the different structure of transmission, transmission fluid can be divided into automatic transmission fluid and manual transmission fluid. Too much or too little transmission fluid will damage the transmission. Excessive oil may cause excessive resistance to the operation of parts, or cause the transmission fluid to blister and deteriorate, resulting in abnormal wear of parts. For manual transmission, it is generally checked almost every 10,000 kilometers, and its replacement cycle is generally 60,000 kilometers; for automatic transmission fluid, its replacement cycle is longer, and it is generally replaced every 80,000 kilometers.

5. Power steering fluid

The replacement cycle of power steering fluid is generally longer, and it is recommended to replace it once every 2 years or 40,000 kilometers. Generally speaking, it is enough to check it every six months. Power steering fluid inspection also includes oil loss and contamination. It is a bit difficult to judge whether the power steering fluid is good or bad because there is no reference standard, but in general, new power steering fluid is usually red with some transparency, while power steering fluid used for a long period of time will turn black and its transparency will be greatly reduced.

The above is the introduction of the five oil and maintenance cycle, the novice may feel so many kinds of oil, maintenance is very troublesome, in fact, it is not, a little bit of understanding, and then use a small notebook to record it will be much clearer, and finally, there are any questions about the car, welcome to private letter or message comments, I will reply to you as soon as possible.
