Emulsified engine oil cannot continue to be used. After emulsification, the oil will produce a white emulsion, and its performance in all aspects will decline. Long-term use of emulsified oil can cause significant harm to the engine. If the engine oil shows signs of emulsification, it is recommended to identify the cause of the emulsification, repair it, and then add new oil. Causes of engine oil emulsification: 1. Water entering the oil; 2. Gasoline entering the oil. During engine operation, the oil is pumped by the oil pump to various parts of the engine that require lubrication, forming an oil film to prevent direct contact between components. If the components inside the engine come into direct contact and generate friction, a large amount of heat will be instantly produced during engine operation, which can be harmful to the engine. Poor engine cooling can directly lead to cylinder scuffing or even more severe damage. Engine oil not only lubricates but also cleans, seals, cushions, dissipates heat, and prevents rust within the engine.
