要了解，不同環(huán)境不同駕駛習(xí)慣和需求，甚至不同的機(jī)油品牌和種類都讓這個(gè)數(shù)據(jù)具有很多的不確定性。在這里教大家兩個(gè)方法，讓你自己就可以準(zhǔn)確判斷機(jī)油是否要更換。下面濟(jì)南寶馬汽車專修人員為您分析：

It is important to understand that different driving habits and needs in different environments, as well as different oil brands and types, all contribute to many uncertainties in this data. Here are two methods to teach you, so that you can accurately determine whether the oil needs to be replaced. The following is an analysis by Jinan BMW auto repair personnel:

1、通過機(jī)油試紙來觀察

1. Observe with oil test paper

通過機(jī)油尺中取出少量機(jī)油滴在機(jī)油試紙上，然后靜止放置一個(gè)晚上，等待上面的機(jī)油在試紙上完全擴(kuò)散。如果擴(kuò)散的機(jī)油油環(huán)、沉淀環(huán)、擴(kuò)散環(huán)之間的邊緣越硬，則機(jī)油性能衰減就越厲害。

Take a small amount of oil from the oil dipstick and drop it onto the oil test paper, then stand still for one night, waiting for the oil on the test paper to completely diffuse. If the edges between the diffused oil ring, precipitation ring, and diffusion ring become harder, the performance of the oil will deteriorate more severely.

2、根據(jù)換機(jī)油后的駕駛感覺來判斷

2. Judging by the driving feeling after changing the oil

機(jī)油的性能都有“保質(zhì)期”，在某一時(shí)期當(dāng)你覺得動(dòng)力“很肉”，加速緩慢時(shí)，這就說明機(jī)油的“保質(zhì)期”到了，要去更換機(jī)油了。

The performance of engine oil has a "shelf life". At some point, when you feel that the power is "meaty" and the acceleration is slow, this indicates that the "shelf life" of the engine oil has expired and you need to change the engine oil.

另外當(dāng)你更換了機(jī)油后，感覺到有明顯的動(dòng)力提升，那說明上次更換機(jī)油的里程有點(diǎn)太長了。下次可以適當(dāng)提前500公里，這樣1-2次你就可以找到一個(gè)比較準(zhǔn)確的更換機(jī)油的里程。

In addition, when you change the oil, you feel a significant power increase, which indicates that the mileage for the last oil change was a bit too long. Next time, you can appropriately advance the mileage by 500 kilometers, so that you can find a more accurate mileage for changing the oil 1-2 times.

一般情況下，只需按照機(jī)油或者保養(yǎng)手冊上建議的保養(yǎng)里程進(jìn)行更換就已足夠。在惡劣駕駛環(huán)境下，則養(yǎng)成定期觀察機(jī)油情況的習(xí)慣，發(fā)現(xiàn)有變質(zhì)傾向則及時(shí)更換之。

Generally, it is sufficient to replace the oil or the recommended maintenance mileage in the maintenance manual. In harsh driving environments, develop the habit of regularly observing the condition of the oil, and promptly replace it if there is a tendency to deteriorate.

還要提醒一下大家的是，更換機(jī)油的同時(shí)好把機(jī)油濾也一并換掉。機(jī)油濾的作用是攔截下機(jī)油中的雜質(zhì)，如果不及時(shí)更換，上面累積的雜質(zhì)就會造成堵塞。輕則會造成機(jī)油壓力不足，機(jī)械部件潤滑不好，嚴(yán)重的還會造成發(fā)動(dòng)機(jī)過度磨損。還有什么問題就來我們網(wǎng)站http://www.cnjqf.com咨詢！

Also, I would like to remind everyone that when you change the engine oil, you should also replace the engine oil filter. The function of the engine oil filter is to intercept impurities in the lower engine oil. If it is not replaced in a timely manner, the accumulated impurities on it will cause blockage. If it is light, it will cause insufficient oil pressure, poor lubrication of mechanical components, and even excessive engine wear.
