How much common sense do car owners know about car maintenance?

For the majority of car owners, starting a car is tantamount to declaring it as their own private goods, and it goes without saying that they will cherish it. However, there has always been a question, that is, how much do car owners know about the common sense of car maintenance?

After good maintenance, just two or three years, the car is still the same as a new car, with high value preservation, good condition control and no lower resale price.

Therefore, it is really important to learn to master the knowledge of car maintenance, so as to avoid being stuck and know more about cars. Then, let's talk about the common sense of car maintenance at eight o'clock.

Oil change frequency

There are three kinds of engine oils.

Mineral oil: it is the worst engine oil, and there are many magazines. It is the remaining oil after gasoline and heavy oil in petroleum are extracted. (Car owners are advised to choose and distinguish carefully)

Semi-synthetic oil: There are a lot of additives in oil, including antioxidants and preservatives.

All synthetic engine oil: It is the best engine oil with many raw materials, which can effectively improve the lubricity and stability of the engine.

Four important filter elements

Oil filter element: the replacement cycle can keep the frequency with the oil.

Air-conditioning filter element: if it is not replaced for a long time, it will breed bacteria, scale and smell bad. Although it is no problem to change it once a year, it is still recommended to change it before winter and summer.

Gasoline filter: according to the mileage, 10000-20000 km, it will be fine.

Air filter: This can last longer. In general, it should be replaced every 20,000 kilometers or 1-2 years.

Service life of tire

Generally, after 50-80 thousand kilometers, the tread depth of the tire will wear a lot. When it is lower than 1.6mm, it can be replaced for safety reasons. Although many tire tracks around us are badly worn and have not been replaced, there are still hidden dangers. You can't be sure that you will have a flat tire on a very hot road!

Brake oil circulation

Some car owners who have been driving for 78 years have despised brake oil. If you think so, it's all wet. Brake oil is related to braking, which determines the safety factor when driving. For the sake of prudence, it still needs to be replaced.

Generally, the replacement period is about 3 years or 60,000 kilometers, whichever comes first. Affected by high humidity, it needs to be replaced every two years.

Naturally, according to different models, the replacement cycle will be different, so you can check the maintenance manual accurately.

Importance of brake pads

Brake pads determine the safety factor of the owner when driving. It is suggested to replace it after 30,000-40,000 kilometers. Some people say that 40,000-60,000 kilometers is also ok.

According to the actual situation, the thickness of the new brake pad is about 1.5cm, and the old brake pad whose thickness is less than 0.5cm needs to be replaced. Moreover, in the process of use, whether the brakes have abnormal sound, the owner can feel it, and the technologically innovative on-board system will also give early warning tips.

Life of timing belt:

As an important part of the engine valve system, the timing belt is connected with the crankshaft, and it also cooperates with a certain transmission ratio to ensure the time accuracy of intake and exhaust.

The life of timing belt is shorter than that of metal gear, and the belt is exposed outside the engine. After a long time, the surface of the belt will begin to age and even crack. Problems such as belt slippage will lead to the consequences of belt aging and fracture: the engine will top the valve, and then the valve, piston and crankshaft will be scrapped.

Antifreeze coolant

The antifreeze coolant contains special additives, which are very important and used in the cooling system of liquid-cooled engines.

It can prevent freezing in winter and boiling in summer, and can well prevent the radiator from bursting and freezing the engine cylinder block or cylinder head. It also has excellent performance of anti-scaling and anti-corrosion all year round.

The replacement cycle is usually one to two years, and the car is in good condition. It is also possible to postpone it for a year or two, depending on the condition of the car.

Spark plug

It can be said that engine oil is the blood of the car, the engine is the heart of the car, and the spark plug is the heart of the engine. The starting of the engine requires the ignition of the spark plug and ignition.

The great function of the spark plug is to introduce the high voltage electricity generated by the ignition coil into the engine cylinder and generate sparks between the spark plug electrodes to ignite the mixture.

Spark plugs are divided into two types: resistance type and platinum type. The service life of resistors is generally about 20,000 kilometers, and that of platinum is about 40,000 kilometers. Selectively look at the owner himself.
