The blackening of lubricating oil does not mean deterioration[汽车修理知识]

OKlubricating oilIs the key to maintenance, we must givecarInstall high-quality lubricants.
Engine oil works under severe high temperature conditions, and is prone to oxidization and deterioration, producing acidic substances and superimposing polymer deposits, which will damage lubrication.In addition, the combustion exhaust gas flees intoCrankshaftThe tank also promotes oxidation and deterioration of engine oil. Therefore, after using for a certain period of time, the engine oil usually turns black and deteriorates and loses its proper lubricating effect. However, with the continuous improvement of the quality of lubricating oil, especially the popularization and use of thickened engine oil, the blackening of engine oil does not necessarily mean that the engine oil has deteriorated. This is because the clean dispersant added to the thickened engine oil disperses the deposits on the parts in the oil, making the engine oil black. Whether it has deteriorated, various indicators should be tested, and the oil should be changed regularly according to the quality to reduce unnecessary waste.
