秋冬季节气温下降比较明显，普通润滑油产品在气温低的情况下则变得更稠，流动性减弱，达到需要润滑部位的时间加长，致使车辆不易启动且磨损加大。所以
济南变速箱油厂家建议低温季节应尽量选择冬夏通用机油！
In autumn and winter, the temperature drops obviously. Common lubricating oil products become thicker and less mobile when the temperature is low, and the time to reach the position requiring lubrication is longer, which makes the vehicle difficult to start and wear more. Therefore, the manufacturer of Jinan transmission oil suggested that the winter and summer general oil should be selected as far as possible in the low temperature season!
选择润滑油应根据发动机的要求进行选择，润滑油的选择可在厂家的基础上向上升一级，或选用合成机油性能更佳。
The selection of lubricating oil shall be based on the requirements of the engine. The selection of lubricating oil can be improved by one level on the basis of the manufacturer's recommendation, or the performance of synthetic oil is better.
应尽量选择冬夏通用机油。通用机油无论温度如何变化都能保持较稳定的润滑性能，对发动机起到较好的保护作用。
Winter and summer general oil shall be selected as far as possible. No matter how the temperature changes, the universal oil can maintain a more stable lubricating performance and play a better role in protecting the engine.
视发动机的状况选择。如果发动机是新的或者状况良好的，应尽可能使用黏度较低的机油，比如0W-40、5W-40和10W-40等，以使润滑油的流动更快，减少启动时的磨损。
Select according to the condition of the engine. If the engine is new or in good condition, oil with low viscosity, such as 0W-40, 5W-40 and 10W-40, should be used as far as possible to make the lubricating oil flow faster and reduce wear during startup.
如果是在高温季节或发动机已经磨损到一定程度的，就要选用高黏度的机油，比如15W-50等，这样有利于形成较厚的油膜，维持机油的压力，并减少机油消耗。
If the engine is worn to a certain extent in the high temperature season, high viscosity oil, such as 15W-50, should be used to form a thicker oil film, maintain the oil pressure and reduce oil consumption.
鉴别润滑油优劣，一般要注意几点：一是观察。机油若清澈，呈黄棕色，说明其品质较好;若颜色浑浊或乳化，说明含水多;如机油有灼烧气味，说明过早氧化或混入其他油品。二是查看是否有沉淀物。
In general, several points should be paid attention to when identifying the advantages and disadvantages of lubricating oil: first, observation. If the engine oil is clear and yellowish brown, it indicates that its quality is good; If the color is turbid or emulsified, it indicates that there is much water; If the engine oil has burning smell, it indicates premature oxidation or mixing with other oils. Second, check whether there is sediment.
三是可以将机油滴在110℃以上铁板或排气管上，如出现爆声，说明机油含有水分。四是将机油滴在滤纸上，用斑点法图谱对照。一般情况下，机油应保持适合黏度、中和性、氧化安定性、耐磨性和耐腐蚀性。
Third, the engine oil can be dropped on the iron plate or exhaust pipe above 110 ℃. If there is an explosion, the engine oil contains water. Fourth, drop the engine oil on the filter paper and compare it with the dot method. In general, the engine oil shall be suitable for viscosity, neutralization, oxidation stability, wear resistance and corrosion resistance.
The above is the answer to the question that winter and summer general oil should be selected as much as possible in low temperature season. You can come to our website at any time if you have any ideas http://www.jnbsx.com Understand!
