機油變黑就必須換是嗎？

　　潤滑油變黑了，就該換油了?
　　The oil has darkened, and it's time to change the oil?
　　介個就是樓主遇到的問題了。有的盆友認為：潤滑油顏色變黑就是油品嚴重變質的變現，那就得換。其實這只是對于沒有加清靜分散劑的潤滑油來說，但現代汽車使用的潤滑油一般都加有清靜分解劑。這種清靜劑會將粘附在活塞上的膠膜和黑色積炭洗滌下來，并分散在油中，從而減少發動機高溫沉淀物的生成，所以潤滑油使用一段時間后顏色容易變黑，但這并不意味著油品已經變質。
　　The subject is the problem that the landlord has encountered. Some friends think: the color of the lubricating oil is black is the serious metamorphism of oil products, it must be changed. In fact, this is only for the lubricating oil without the dispersing agent, but the lubricating oil used in the modern car is usually added with the static decomposing agent. This kind of quiet agent will wash the adhesive film and black carbon on the piston and disperse it into the oil, so as to reduce the generation of high temperature sediment. Therefore, after a period of time, the color of the lubricant will darken, but this does not mean that the oil has deteriorated.
　　保養店的師傅經常攛掇樓主換潤滑油，要不是他不夠，沒有認識到這一點，要不就是坑樓主，想多賺點錢。這樣的“黑店”，樓主以后還敢去?
　　The master often recommend the maintenance shop landlord for lubricating oil, but he is not professional, not aware of this, or is the pit lord, want to make more money. This "black", the landlord later dare to go?
　　潤滑油經常添不用換?
　　Does the lubricating oil often be added?
　　剛才說了，有清凈分解劑的潤滑油變黑是正常的，不用換，可也不能總是只加不換啊!只補充不換只能彌補機油數量上的不足，卻無法完全補償潤滑油性能的損失。樓主應該知道，潤滑油在使用過程中，由于污染、氧化等原因質量是會變差的，同時還會有一些消耗，使數量減少。為了能使潤滑油充分發揮它的性能，使用一段時間后還是需要換的。
　　Just now, the black oil with detergent and decomposition agent is normal. It can't be changed without changing. It can't always add and replace. It only compensates for no replacement, which can only make up for the shortage of oil quantity, but it can't completely compensate for the loss of lubricating oil performance. The landlord should know that the quality of the lubricating oil will be worse due to pollution and oxidation during the use process, and at the same time, there will be some consumption and quantity reduction. In order to enable the lubricating oil to give full play to its performance, it needs to be replaced after a period of time.

                                         
　　有時候添加劑用處大
　　Sometimes the additives are very useful
　　有些盆友認為，在潤滑油里添加添加劑，能發揮好的作用。在這里，可以負責任的告訴樓主，這種理解是錯誤的!真正優異的潤滑油是具備多種發動機保護功能的成品，配方中已含有多種添加劑，其中包括抗磨劑，而且潤滑油講究配方的均衡以保障各種性能的充分發揮。
　　Some friends of the basin think that adding additives in the lubricating oil can play a better role. Here, you can responsibly tell you, this is a misunderstanding! Really good lubricants have a variety of engine protection products, a variety of additives containing formulations, including antiwear agent, lubricating oil and give full play to the most exquisite formula to ensure the balanced performance.
　　自行添加其他添加劑不僅不能給車輛帶來額外保護，反而易與機油中的化學物質發生反應，造成機油綜合性能變差。這不是畫蛇添足么?
　　Adding other additives can not only bring additional protection to vehicle, but also react with chemical substances in oil, resulting in poor comprehensive performance of oil. This is not superfluous?
　　機油能多加就多加?
　　How much will the oil add?
　　還有些盆友認為，潤滑油能多加就多加，好像加少了就會吃虧一樣，每次都要加滿。唉~怎么就那么看不開呢!告訴樓主，潤滑油量應該控制在機油尺的上、下刻度線之間為好。因為潤滑油過多就會從氣缸與活塞的間隙中竄入燃燒室燃燒形成積炭。
　　Also some friends believe that the oil can be added more, as if the loss of the loss will be the same, every time to fill. Alas, how can not see so! Tell the landlord that the quantity of lubricating oil should be controlled between the upper and lower scale of the oil scale. Because the lubricating oil is too much, it will burn from the gap between the cylinder and the piston and burn into the combustion chamber to form the coke.
　　積碳可不是啥好東西!這些積炭會提高發動機壓縮比，增加產生爆震的傾向;積炭在汽缸內呈紅熱狀態還容易引起早燃，要是落入汽缸會加劇汽缸和活塞的磨損，還會加速污染潤滑油。
　　Carbon is not what good stuff! These deposits will increase the compression ratio of the engine, increase the tendency to produce knock; coke in the cylinder are red state but also easy to cause early burning, if you fall into the cylinder will aggravate the wear of the cylinder and piston, will accelerate oil pollution.
