Regardless of whether the car is purchased or not, regular maintenance must not be lacking. Usually, maintenance refers to changing the engine oil filter or doing more oil triple filters, which is the most basic maintenance. As the mileage increases, basic maintenance cannot be done every time. Other fluids on the vehicle also have a change cycle and need to be replaced promptly after expiration. For example, some rubber parts may age due to time and mileage, and need to be replaced. There is also a common problem of carbon accumulation that every car will encounter. Today, let's talk about how many kilometers should a car undergo a major maintenance? What are the projects?

​

For the vast majority of cars, a major maintenance should be done every three years or 60000 kilometers. Strictly speaking, whichever comes first should prevail and cannot be delayed. However, in practice, it is not a big problem to tow the vehicle according to its condition. For example, after only running 20000 kilometers in three years, do you still need major maintenance? According to personal experience, due to the limited mileage, it is not a problem to delay for six months to a year, and there are also cases where the delay is longer. It is safest to control the specific time and do it on time. If the mileage has arrived, it cannot be delayed, as the mileage is the most important reference indicator.

What items are included in major maintenance? Major maintenance is a rough term, which means that there are quite a few things replaced this time, and it does not specifically refer to the specific items to be done. Generally speaking, the maintenance project of replacing the entire vehicle oil is called major maintenance, which includes engine oil, brake oil, booster oil, transmission oil, and antifreeze. Except for engine oil, all other fluids can be changed every three years or 60000 kilometers, and they can be changed together. There is no need to change them too early, especially transmission oil. Many repair shops or 4S stores offer replacements after 40000 kilometers, and even more so after 20000 kilometers, which is a waste of money.

Along with the replacement of the entire vehicle's oil, there are usually other projects to be done together, and together, it seems that there are many projects to be done. For example, cleaning carbon deposits, replacing spark plugs, replacing timing belts, and replacing batteries are also considered maintenance items for the car. The car that uses timing belts has reached 60000 kilometers in three years, and it just needs to be replaced. Many people will replace it together. It's time for a thorough cleaning of carbon deposits that I haven't done before. Through a comprehensive inspection of the vehicle, components that need to be replaced can be replaced together, with a focus on checking the battery. The lifespan of the battery is about three to five years. If the car is driven very little and the battery is not fully charged for a long time, the battery in a car that has been in use for three years is almost reaching its lifespan.

In short, major maintenance involves many tasks, and the entire vehicle's oil must be replaced because the oil has a shelf life. After expiration, not only will its performance decrease, but it may also affect the lifespan of the components that use the oil. Other projects can be selectively replaced or maintained according to the actual situation. For those with clear mileage and time requirements, it is recommended to do so simultaneously. Timely major maintenance can ensure that the performance of the car does not deteriorate and extend the lifespan of various components, which is crucial for maintenance.
