Auto Repair Knowledge | Do you know about car oil?

1. Anti-rust and anti-corrosion: The oil will form an oil film on the surface of the part through the movement of the part. This oil film can be adsorbed on the surface of the part to prevent water, air, etc. from contacting the surface of the part and causing the part to corrode and rust.

2. First, determine the appropriate quality level according to the structural characteristics of the engine. Generally speaking, high-grade oil can replace low-grade oil. If conditions permit, try to choose a higher level of engine oil, because it can provide better protection for the engine.

3. The maintenance cycle of different vehicles and the use of different specifications of oil is different. The oil replacement cycle of general household vehicles is 8,000km and 10000km or one year. If any of the two indicators reach one, they need to be replaced. The other is the amount of oil and whether the oil deteriorates. When the oil deteriorates and emulsifies or burns the oil, the oil should be replenished or replaced in time.

What kind of oil does the car add

1. There are the following types of oil added to the car: Engine oil: Engine oil is the heart and blood of the engine.There are many metal parts that rub against each other in the engine. The friction speed is fast, the surface is rough, and the working temperature is as high as 400°C-600°C. Only qualified lubricating oil can reduce the loss of the engine.

2. Gasoline engine vehicles need to add gasoline, and diesel engine vehicles need to add diesel. The fuel mark used can be seen directly on the fuel tank cap of the vehicle. It is necessary to refuel the motor vehicle according to the fuel mark specified on the fuel tank cover in order to drive stably.

3. So what number of gasoline is usually added to ordinary cars? Just add No. 92 gasoline to ordinary cars. If you don't know what size of oil is appropriate for your vehicle, you can check the instructions of the position of the fuel tank. The fuel label will be marked on the inside of the gasoline cover, and you can refuel according to the requirements.If the car adds the wrong high-label oil, it will have no effect on the car.

4. If the compression ratio is 5 to 5, choose No. 92 gasoline. If the compression ratio is 5 to 5, choose No. 95 gasoline. If the compression ratio is more than 5, choose No. 98 gasoline. The specific choice of gasoline is determined by the compression ratio of the engine.

5. Cars can use No. 92, No. 95, No. 98 gasoline and diesel, No. 92 gasoline and No. 95 gasoline. Add No. 92 gasoline to the naturally aspirated engine, and add No. 95 gasoline to the turbocharged engine. Diesel is more powerful than ordinary gasoline, has lower emissions, and is more energy-saving and environmentally friendly.

6. Gasoline vehicles need to be filled with gasoline, and diesel vehicles need to be filled with diesel. The fuel label used can be seen directly on the fuel tank cover of the vehicle. You need to refuel the motor vehicle according to the fuel label indicated on the fuel tank cap in order to drive stably.

What are the oils used in cars

Five kinds. Oil, brake fluid, fuel oil, transmission fluid and steering assistance fluid. Among them, brake fluid achieves braking by uniformly transmitting pressure, which has four functions: energy transfer, heat dissipation, anti-corrosion and anti-rust and lubrication.

Transmission oil:Transmission oil is an oil supply that keeps the gear system clean, which can ensure the normal operation of the gearbox and help extend the life of the transmission installation.

Car lubricants include engine oil, transmission oil, brake fluid and car grease. Among them, the transmission oil includes automatic transmission oil and gear oil, and the automatic transmission oil can be used in direction assistance.

Engine oil, power steering oil, transmission oil, brake fluid, fuel (gasoline and diesel). Cars should generally be replaced or added with "five oils and three water". "Three waters" refers to engine antifreeze cooling water, glass water and battery water, and "five oils" refers to engine oil, fuel, transmission oil, brake fluid and power steering oil.

Cars can use No. 92, No. 95, No. 98 gasoline and diesel, No. 92 gasoline and No. 95 gasoline.Add No. 92 gasoline to the naturally aspirated engine, and add No. 95 gasoline to the turbocharged engine. Diesel is more powerful than ordinary gasoline, has lower emissions, and is more energy-saving and environmentally friendly.
