What is five oils and three waters?

I believe that many car owners have only learned about the maintenance knowledge of their cars during their short study in driving schools, but the fur they have mastered may not be able to effectively maintain their cars, so as to keep them in good condition. When it comes to maintenance knowledge, a very basic question may be unavoidable, that is, what are the five oils and three waters of a car? Many drivers with long driving experience may not know it, but they need to understand the basic knowledge of these cars.

let's talk about the five oils in the car, which refer to gasoline, engine oil, gearbox oil, brake oil and steering power-assisted oil. Among them, gasoline is the most commonly contacted by everyone. Even many people who don't drive know that it is a kind of fuel. The gasoline engine has to rely on its combustion to generate power and drive the vehicle forward.

in addition to the gasoline that you have to go to the gas station to add almost, engine oil is the most common automobile oil that car owners come into contact with. The role of engine oil is to lubricate the engine parts, and at the same time, it has auxiliary functions such as preventing the engine from rising too high and resisting corrosion! The oil needs to be changed in different time or mileage according to different models. It is recommended to change it regularly according to the relevant contents indicated by the manufacturer in the vehicle manual.

the function of the gearbox oil is to keep the internal components of the gearbox clean, and at the same time, it can also play the role of lubrication, making the shift smoother. The service life of gearbox oil is very long, and it usually needs to be replaced after two years or more than 5 thousand kilometers.

however, this work has to be carried out in a 4S shop or a garage, and special equipment is needed. Next, let's talk about brake oil, that is, brake fluid, which plays a key role in transmitting braking force in the brake system, so maintaining its performance is very important for driving safety. The replacement cycle of brake oil is generally two years. Whenever the time is approaching, many auto repair shops or 4S shops will remind the owners to replace it, which is related to life safety. Don't be careless.

the last of the five oils is the power steering oil. This only appears in power steering systems that use mechanical or electro-hydraulic power. Nowadays, most vehicles adopt electric power steering system without steering power oil, so there is basically no problem of replacement.

After the five oils are finished, let's briefly talk about what Sanshui is. In fact, it is antifreeze coolant, glass water and battery electrolyte. Now most automobile batteries are maintenance-free, and the electrolyte basically does not need to be added by the owner himself. However, antifreeze coolant and glass water can basically be determined by observation whether they need to be added. Generally speaking, glass water is added after use.
