It is reported that Kunlun has introduced summer lubricants for summer car owners. Summer is a frequent occurrence of automobile troubles. Due to the high temperature in the summer, automobile lubricating oils are vulnerable to heat thinning, which causes deterioration of their oxidation resistance, perishability, and even causes failures such as burning of shafts and holding shafts. Kunlun Lubricant Technical Experts said that the lubricating oil is divided into single-grade oil and multi-grade oil. Different types of lubricating oils have different replacement conditions. During the season, pay attention to checking engine oil usage. If the car uses single-stage lubricants in winter, it should be replaced in time when summer comes. Single-stage lubricants suitable for use in winter have poor viscous temperature performance. After the engine reaches a certain temperature, the engine cannot be normally lubricated, and engine wear increases. Experts advocate that vehicles use multi-grade oils that are common in winter and summer. Compared with single-stage oils, multi-grade oils are not only common in winter and summer but also provide better lubrication. In a hot environment, the engine is working for a period of time, does not change oil for a long period of time, and frequent start-stops can generate harmful sludge in the engine. These sludges will cause a drop in lubrication, blockage of the oil passages, sticking of valves, hydraulic tappets and piston rings. Failure to clean them in time will shorten the life of the engine.
