Automobile oil has the functions of lubrication, sealing, cleaning and heat dissipation. Automobile maintenance and maintenance are inseparable from oil. So how to choose oil is the care of your car?

什么样的润滑油才是适合自己爱车的？

What kind of lubricant is suitable for your car?

贵的并一定就是好的，润滑油的好坏重要的是基础油，润滑油80%都是基础油，只有的基础油才能生产处更好的润滑油，才能帮助发动机减少磨损，延长寿命，且还可以延长汽车换油周期、减轻维护和修理的频度以及难度。所以选购机油主要还要看基础油，好的基础油作为原料，具有很强的高低温粘度保持性能，可以在发动机表面形成充分的油膜，具有较好的抗磨损性，还可以确保发动机在极温环境下运转自如。

The expensive one is not necessarily good. The quality of lubricating oil is the base oil. 80% of the lubricating oil is base oil. Only high-quality base oil can produce better lubricating oil, help the engine reduce wear and prolong its service life. Moreover, it can also extend the oil change cycle, reduce the frequency and difficulty of maintenance and repair. Therefore, the selection of engine oil mainly depends on the base oil. Good base oil as raw material has a strong high and low temperature viscosity retention performance, can form a sufficient oil film on the engine surface, has good wear resistance, and can also ensure that the engine can run freely in extreme temperature environment.

原厂汽车机油需要更换吗？

Does the original automobile oil need to be changed?

厂家虽然要计算成本、性能以及等因素，但是也总有底线吧，所以原厂油一般性价比高，一定可以保证车辆能够达到基本理想的工作状态。其实一辆车并不是适合那些好的，贵的机油，厂家选用0W-30还是5W-40等标号的机油，是工程师精密计算，进过实地考察测试出的结果，所以大家如果换机油也要根据车辆的实际情况来更换。当然如果你生活在寒冷的东北地区，那么使用0W-20标号的机油，如果你生活在炎热的海南，那么就要使用10W-40标号的机油了，所以更换机油还要根据自己生活的地区来进行更换。

Although the manufacturers have to calculate the cost, performance and price and other factors, there is always a bottom line. Therefore, the original oil is generally cost-effective, which can ensure that the vehicle can achieve the basic ideal working state. In fact, a car is not suitable for those good, expensive oil. The manufacturer chooses 0W-30 or 5W-40 engine oil, which is the result of precise calculation by engineers and field investigation. Therefore, if you change the engine oil, you should also change it according to the actual situation of the vehicle. Of course, if you live in the cold northeast region, it is recommended to use 0w-20 oil. If you live in hot Hainan, you will need to use 10w-40 oil. Therefore, the oil should be changed according to the area where you live.

夏季和冬季是否使用不同的机油？

Are different oils used in summer and winter?

冬天大家肯定要盖厚被子，到了夏季可能只是什么都不用盖都可以，所以季节不同可以换适当的机油，不过这不是方案。这就跟冬季并没有那么多人愿意更换冬季轮胎是一个道理。如果你很在意烟台汽车保养车辆可以根据季节更换机油，如果你觉得这样做太麻烦也可以选用四季通用的机油，比如0W-40W。

In winter, we must cover with thick quilts. In summer, we may just need nothing to cover, so we can change the proper oil in different seasons, but this is not the only solution. This is the same reason that there are not so many people willing to change winter tires in winter. If you care about Yantai car maintenance, you can change the engine oil according to the season. If you think it is too troublesome to do so, you can also choose the engine oil of four seasons, such as 0w-40w.

汽车机油有哪些分类？

What is the classification of automobile oil?

机油一般分为三类：矿物油、半合成机油和全合成机油。

Oil is generally divided into three categories: mineral oil, semi synthetic oil and fully synthetic oil.

矿物质油，提炼精度不高，流动点较高，也就是说低温流动性差，所以不适合寒带地域使用。

Mineral oil, refining precision is not high, high flow point, that is to say, low temperature fluidity is poor, so it is not suitable for use in cold regions.

半合成机油，是矿物油的基础上经过加氢裂变技术提纯后的产物，纯度非常接近全合成机油，是矿物油向合成油的理想过度产品。

Semi synthetic engine oil is a product purified by hydro fission technology on the basis of mineral oil. Its purity is very close to that of full synthetic oil. It is an ideal transition product from mineral oil to synthetic oil.

全合成汽车机油，这个是利用化学方法合成的各种汽车机油的来的，汽车机油品质更好，性能更优，使用的时候也会有所感受：冷启动更加顺畅；更加省油；换油周期更长；延长发动机寿命，减少维修率；这种汽车机油因为清净性能优越，所以发动机缸体也更清洁。

Fully synthetic automobile oil, which is made of various automobile oils synthesized by chemical methods, has better quality and better performance. It can also be felt when used: smoother cold start; more fuel saving; longer oil change cycle; longer engine life and less maintenance rate; this kind of automobile oil has superior detergency, so the engine block is cleaner 。
