汽车润滑油保质期是多久?

来源:https://www.smxnykj.com/ 发布时间:日期:2022-08-05
一般来说,外包装好的机油保质期一般为4-5年。为何要注重一下外包装好的机油?是因为汽车机油的质变关键与水份和氧有关系。
Generally speaking, the warranty period of packaged engine oil is generally 4-5 years. Why should we pay attention to the packaged oil? It is because the key to the qualitative change of automobile oil is related to moisture and oxygen.
水份对润滑油的危害,汽车机油里的许多添加物会由于水份而无效,加快汽车机油空气氧化质变的全过程,并且汽车机油空气氧化之后形成的化学物质会进一步危害汽车机油,这么恶循环下来。通常情况下汽车机油里的水分含量在0.03%下列,当水分含量超出0.1%时,汽车机油里的添加物就失效了。
The harm of water to lubricating oil, many additives in automobile oil will be ineffective due to water, which will accelerate the whole process of air oxidation of automobile oil, and the chemical substances formed after air oxidation of automobile oil will further harm the automobile oil, so the vicious cycle. Generally, the moisture content in the automobile oil is below 0.03%. When the moisture content exceeds 0.1%, the additives in the automobile oil will fail.
然后就是氧,这儿说的氧要以多种多样形状存在的,和水份一样,氧都是危害汽车机油里的各种添加物,并且别觉得仅有好机油添加剂才多,什么机油里都是有添加物。特别是在是在太阳光照射或是持续高温前提下,空气中的氧气与润滑油的反映迅速。
Then there is oxygen. The oxygen here should exist in a variety of shapes. Like water, oxygen is all kinds of additives that harm automobile oil. Don't think there are only good oil additives. There are additives in all kinds of engine oil. Especially under the premise of sunlight irradiation or continuous high temperature, oxygen in the air and lubricating oil react rapidly.
然后是残渣的危害,这就无需多说了吧,汽车机油肯定是纯粹的化学物质,汽车机油中渗入残渣会危害汽车机油润化实际效果,乃至造成发动机异常损坏,从而危害其密封性特性。
Then there is the harm of residues. Needless to say, automotive oil must be pure chemicals. The infiltration of residues into automotive oil will endanger the actual effect of automotive oil lubrication, and even cause abnormal engine damage, thereby endangering its sealing characteristics.
