冬季气温下降比较明显,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。所以最好选择基础黏度小、倾点低的润滑油产品,这样才能对汽车引擎持续带来良好的润滑作用。首先,选择润滑油应根据发动机的要求进行选择,既不能在要求较低的发动机上使用过于高级的机油,也不能将较低级的机油使用在要求较高的发动 The temperature drop in winter is more obvious. Ordinary lubricating oil products become thicker in low temperature conditions and have weaker fluidity, resulting in longer time for parts needing lubrication, resulting in less starting of the vehicle and more wear and tear. So it is best to choose the basis of low viscosity, low pour point lubricant products, so as to continue to bring a good engine lubrication of the engine. First of all, the choice of lubricant should be based on the requirements of the engine to choose, neither in the less demanding engine to use too high level of oil, can not be used in lower-level oil in the higher requirements of the start
