First of all, it's very clear that there are two standards for car maintenance: time and mileage. It's generally accepted that the first one to do the maintenance is no doubt. However, there are still some problems that need our attention. For example, what problems should we pay attention to when we are car riders? Let's first clarify a few problems.

一般來說，我們車友都普遍覺得按照車子行駛的里程數(shù)來做保養(yǎng)是沒什么問題的，畢竟你車子跑了這么多了，不論是汽車的零部件啊，還是一些機(jī)油冷卻液之類的，都有一定的磨損和消耗，所以理所當(dāng)然到了規(guī)定里程數(shù)要保養(yǎng)，但是，如果我車子都沒怎么開，那為什么我還要花錢去做這個保養(yǎng)呢?

Generally speaking, we riders generally think that it's no problem to do maintenance according to the mileage of the car. After all, your car has been running so many kilometers, whether it's the parts of the car, or some oil and coolant, they all have certain wear and consumption, so it's natural to have maintenance at the specified mileage. However, if I don't drive my car much, Then why do I have to pay for this maintenance?

多車上的用品以及車子的部件都是有保質(zhì)期的。咱們就說機(jī)油吧，我們使用機(jī)油一旦開封，加入到發(fā)動機(jī)中，這期間必定是要跟空氣等接觸的，即便你車子不運轉(zhuǎn)，機(jī)油也只能在它的保質(zhì)期中才能發(fā)揮更好的潤滑作用，一旦過了保質(zhì)期，可能這個機(jī)油的很多性能就大不如前了，那帶來的必然是發(fā)動機(jī)的一些磨損等問題。

Many of the car's supplies and car parts have a shelf life. Let's talk about engine oil. Once the engine oil is opened and added to the engine, it must be in contact with the air during this period. Even if your car doesn't run, the engine oil can only play a better lubricating role in its shelf life. Once the shelf life is over, many properties of the engine oil may not be as good as before, which inevitably leads to some wear of the engine And so on.

這個道理很簡單，就像你買了一瓶飲料，打開喝了一口，那你再放著肯定保質(zhì)期就要縮短了，可能第二天還能喝，但你心里也不舒服，覺得過保質(zhì)期了，因為人家提醒了，開蓋即飲。

The reason is very simple. If you buy a bottle of drink and open it for a sip, you will surely shorten the shelf life if you put it again. You may be able to drink it the next day, but you are also uncomfortable. You feel that the shelf life has passed, because people remind you to drink immediately after opening the lid.

而這些汽車相關(guān)的東西的保養(yǎng)周期都是廠家經(jīng)過各種不同的形式路況和用車條件去做試驗，然后根據(jù)這些試驗結(jié)果調(diào)整做出的適合的保養(yǎng)時間間隔。

The maintenance cycle of these car related things is that the manufacturer carries out tests under various road conditions and vehicle conditions, and then adjusts the appropriate maintenance interval according to the test results.
