Automobile lubricating oil is also called oil, assuming that the engine is compared to the heart of the car, the oil is the blood of the car, although we all know the importance of automobile lubricating oil, but most owners are still a "oil blind", let others pit. Oil as a lubricant for cars, not only lubrication, anti-wear, shock buffering, as well as cooling, cleaning, rust, corrosion, oxidation. Of course, the quality of lubricating oil can also directly affect the normal operation of the initiator, and it also plays a key role in our driving safety. The following are all dry goods engine oil, we all know that every maintenance shop will remind us how many kilometers to come and change it, you can imagine its importance! The starter is the source of all the power of the car, and the friction surface bears a lot of load. The temperature of the friction surface is high, and the viscosity of the lubricating oil is easy to decrease, forming the oil film. Then, the high temperature and high pressure quenching gas will leak into the crankcase through the gap, contaminating the lubricating oil and accelerating oxidation. Assuming that the working temperature difference is large, the parts will also be thermal expansion and thermal deformation, and the oil film is difficult to adhere in the changing gap. Finally, the engine has a lot of moving parts, and one lubricating oil can do everything. Isn't it expensive for a reason?

Transmission gear oil

Whether manual transmission, or automatic transmission, lubricating oil is also an essential partner of their health work. Different from oil, different automatic transmissions have different technical requirements, even if the same model of transmission configuration in different models, its torque, weight, speed, structure will be different, among which, automatic transmission oil is not only the transmission oil of the hydraulic torque converter, but also the lubricating oil of the planetary gear structure and the hydraulic oil of the shifting device. That is to say, it is used to transmit the power of the engine, but also to lubricate and hydraulic.

Brake oil

Brake oil is called "automobile brake fluid", is used for hydraulic brake system to transfer pressure to stop the wheel rotation of the liquid, its quality is directly related to our driving safety. If you do not change it for a long time, you can clearly feel the lack of braking force when you run at high speed, which will be a big safety hazard. If you do not change it for a long time, you can affect the braking function of the car.

Transmission oil

There are a lot of high-precision gears working inside the gearbox, and the operation of the entire internal system will occur due to the friction of parts and components. At this time, the transmission oil plays a role of lubrication and heat dissipation. In addition, the automatic transmission can flexibly transfer power between the initiator flywheel and transmission gear through the torque converter, and the liquid in the torque converter is transmission oil. Therefore, another role of transmission oil is to transfer power. Cars are like our legs, replacing us to walk and carry the load.
