  济南奥迪专修告诉你,如何判断机油是否坏了?
  Audi experts tell you, how to judge whether the oil is broken?
  一、通过油色观察
  1、 Observe through oil color
  在有阳光的晴天,用对比阳光观察油滴情况;在光线下,可以清楚地看到润滑油无磨屑是好的,可以继续使用,如果磨屑过多,应更换润滑油。
  On a sunny day, observe the oil drop with contrast sunlight; in the light, it is good to see clearly that the lubricating oil has no debris, and it can be used continuously. If there are too many debris, replace the lubricating oil.
  好油呈半透明的黄褐色,褐色中有水,乳白色中有泡沫,发动机已运转一段时间。油的黑色通常是由于油中含有过多的油和铁,或者是油中含有过多的碳颗粒。将油标尺拉出至光亮处观察刻度线是否清晰,当油标尺上的油看不到刻度线时,说明油太脏,需要立即更换。
  Good oil is translucent yellowish brown, brown in water, milky white with foam, and the engine has been running for some time. The black color of oil is usually caused by too much oil and iron, or too much carbon particles in the oil. Pull out the oil scale to the bright place and observe whether the scale line is clear. When the oil on the oil scale cannot see the scale line, it means that the oil is too dirty and needs to be replaced immediately.
  有条件的用户可以选择慢速定性试纸,价格在9-11元(100件/盒)之间,每次油检需要一张试纸,也就是说,每次检测的材料成本约为10美分。
  Conditional users can choose slow qualitative test paper, the price is between 9-11 yuan (100 pieces / box), and one test paper is needed for each oil inspection, that is to say, the material cost for each inspection is about 10 cents.

  观察石油流
  Observe the oil flow
  慢慢地把量杯里的油倒入另一个空杯子里,观察它的流动。优质油品的油流应长、均匀、连续。坏的油是油滴。
  Slowly pour the oil in the measuring cup into another empty cup and observe its flow. The oil flow of high quality oil products shall be long, uniform and continuous. The bad oil is a drop of oil.
  三、手工研磨法
  3、 Manual grinding
  把油放在拇指和食指之间扭磨,摸起来应该有润滑作用,没有磨屑,就没有摩擦,如果你觉得手指之间的砂粒等摩擦较大,那就说明油里有铁屑、油和杂质。
  Put the oil between the thumb and index finger and twist it. It should have lubricating effect. If there is no wear debris, there will be no friction. If you think the friction between the fingers is large, it means there are iron debris, oil and impurities in the oil.
  嗅觉和选择
  Smell and choice
  一般对嗅觉刺激大而有异味的油为劣油,好油应无特殊气味,仅微香。
  Generally, the oil with strong smell stimulation and peculiar smell is poor oil. Good oil should have no special smell, only slight fragrance.
