What do you mean by "five oils and three liquids"? What are their functions?

There are many people who can drive now, but for these drivers, even if they can drive, they are still novices, because they don't know the oil to be added in the engine, and they don't know how long the replacement cycle is.

There are eight kinds of liquids used in automobiles, which are called five oils and three liquids. These five oils are steering power oil, gearbox oil, brake oil, fuel oil and engine oil. These three liquids are electrolyte, antifreeze coolant and glass water. Today, we will introduce five oils and three liquids and their replacement frequency.

1 steering power oil

It is a special liquid for automobile power steering pump, which can make the steering wheel lighter. Steering power oil is not needed by all cars, but only for cars with electric power steering system. For its replacement cycle, the automobile manufacturer has no clear regulations, but in order to prevent the steering power oil from getting dirty and deteriorating, it is recommended to replace it every three years.

2. Lubricating oil

Transmission oil is the abbreviation of automatic transmission oil. It is used for automatic transmission oil, which can keep the transmission gear system lubricated and clean. Due to the different structure of gearbox, gearbox can be divided into manual gearbox and automatic gearbox. For automatic gearboxes, gearbox oil is usually changed every 654.38+0.2 million kilometers, and for manual gearboxes, it is usually changed every two years or 60,000 kilometers.

3 fuel oil

Fuel is the most familiar diesel in cars. Needless to say, everyone knows that it is enough to fill it up when it is used up.

4. Brake oil

Brake oil, also known as brake fluid, has the functions of energy transfer, heat dissipation, corrosion prevention, rust prevention and lubrication. The brake system will wear out, and the brake oil will absorb the moisture in the air. The effect will get worse after a long time. It is recommended to change the brake oil every two years or 40,000 kilometers.

5. Engine oil

Engine oil is engine lubricating oil, which can lubricate the engine and protect it in all directions. It is also called the blood of a car. It can absorb shock, prevent rust, seal and cool. Engine oil can be divided into mineral oil and synthetic oil. Generally speaking, if mineral engine oil is used, it can be replaced every 5,000 kilometers, while in synthetic engine oil, it can be extended to 8,000 to 1 1,000 kilometers. However, in terms of time, it can also be replaced once every six months.

6. Glass water

Glass water, also known as washing liquid, is the clean water of wiper. Many car owners will make their own glass water, but it is recommended that car owners buy special glass water for cars.

7, antifreeze coolant

In summer, antifreeze coolant will reduce the temperature of the water tank. It is recommended to change it once every two years or once every three years.

8. Electrolyte

Electrolyte is the electrolyte of the battery, so it will not be replenished, and the battery will be replaced directly. The battery replacement cycle depends on the usual habits of the owner. Generally speaking, the service life of a car battery is two years. If it is well maintained, it will take about three to four years.
