冬季如果采用低温下粘度较高的机油便会给启动马达、电瓶等增加额外的损耗,同时因内阻加大而增加了油耗;夏季而使用了高温性能不足的机油,则难以在发动机工作过程中形成足够的保护膜,这将引起润滑不足导致机件磨损。根据我国的气候条件,笔者建议大家可以选择全天候型机油(例如SAE15W-40、10W-40、5W-40、5W-50),冬夏通用。 Winter if the viscosity of the oil at low temperature will give the starter motor, batteries and other additional losses, while increasing resistance due to increased fuel consumption; the summer and the use of high temperature performance of oil, it is difficult in the engine working process In the formation of adequate protective film, which will cause lack of lubrication lead to wear and tear parts. According to China’s climatic conditions, I suggest you can choose all-weather oil (such as SAE15W-40, 10W-40, 5W-40, 5W-50), winter and summer.
