经过了整个夏天的高温与雨水,在立秋之后天气转凉的情况下,汽车的“免疫力”大打折扣。专业人士提醒:别忘了给爱车做换季保养。选择适当的机油换季保养的时候,要特别关注一下汽车机油的浓度问题。因为油品的黏度会随温度变化而变化,冬天黏度变高,夏天黏度变低。因此在温度出现变化,天气寒冷时,可以使用黏度较低的机油。 After a whole summer of high temperature and rain, the weather became colder after the autumn, the car’s “immunity ” greatly reduced. Professionals reminded: Do not forget to make car season maintenance. Select the appropriate oil season maintenance, pay special attention to the concentration of car oil problem. Because the oil viscosity will change with the temperature changes, winter viscosity becomes higher, summer viscosity becomes lower. Therefore, when the temperature changes, the weather is cold, you can use a lower viscosity oil.
