There is a saying called "three separates and seven points", but many car owners do not know what to pay attention to when maintaining the car, and often do not do it or spend more money.
Car maintenance is mainly divided into two types, "small maintenance" and "large maintenance". "Big maintenance" involves more content, what projects to do at what time, I believe many car owners have similar questions, today together for you to answer ~
1
The best time for big car maintenance
The optimal distance for major car maintenance is 60,000 to 80,000 kilometers. Because each car has many frequently used parts, they also have their own lifespan, which is easier to damage in long-term use, so it needs to be replaced in a certain period of time.

Car major maintenance project
Generally speaking, "small maintenance" is relatively simple and can be done by yourself, and "large maintenance" is more recommended to be done in the store, which is more professional and more secure.
One | Replace the oil
Engine oil can play a lubrication and wear reduction, auxiliary cooling and cooling, sealing and leak-proof, rust-proof, anti-corrosion, shock absorption buffering on the engine, which is essential to ensure the normal work of the engine, and is a must-do item for every maintenance, and must not be sloppy.
The interval mileage between oil changes varies slightly depending on the level of oil used. For example, ordinary mineral oil can be replaced once for 5000 kilometers, semi-synthetic oil can be replaced once for 7500 kilometers, and full synthetic oil can be replaced once for 10000 kilometers.
If the number of maintenance is small in one year, you can choose a fully synthetic engine oil, the quality is better, even if the mileage is particularly small, it should follow the principle of replacing it once a year.
|| Replace the "four filters"
"Four filters" refers to oil filters, air filters, air conditioning filters, and fuel filters. After a long time of use, these filter elements will either have the problem of blockage, or they will be polluted, affecting the health of the car, and need to be replaced in time.
Three ||| Replace the transmission oil
Although the transmission oil is usually recycled in a confined space, the external influence is small, and it can maintain a relatively stable working state for a long time, but when the vehicle is driven for a long time, the transmission oil will contain a large number of metal particles, and the continued use will not only make the lubrication effect worse, but also accelerate the wear of the parts in the gearbox, and even block the solenoid valve and oil circuit.
|||| Replace the spark plug
The spark plug plays a role in starting the engine, and its quality basically determines the quality of the car engine. Whether the spark plug needs to be replaced can be judged according to the material or through the gap of the spark plug. In general, if there is no damage, the normal value of the spark plug gap is between 0.7 and 1.5mm, and more than this value can be considered for replacement.
10w km is the watershed of spark plugs, even if there is no major problem with the car after this, it is recommended to replace it.
Wu ||||| Replace the brake oil
Brake oil is an important part of the braking system and is very important for the safety of both people and vehicles.
Because the brake oil is easily subjected to heat deterioration and blisters, when braking continuously, the water will first boil and cause the braking effect to become worse or invalid, so the principle of replacement is mainly whether the water content exceeds the standard. After the car reaches 80,000 kilometers, the water content of most cars will exceed the standard, and it is recommended to replace it.
The above five items are mandatory items for "great maintenance". If you find it difficult to remember, there is a simpler and more effective way, that is, regularly and carefully read the vehicle maintenance manual, which is the most tailor-made for your car itself to ensure safety during use.
