[OAugust]

Engine sludge cleaning method: Generally, 4S shops clean engine sludge by adding a cleaning agent to the engine lubrication system. Before changing the oil, the sludge cleaning agent is poured into the engine through the engine oil filler port, and the engine is started to maintain idle operation for 5 to 10 minutes. Then, the engine is turned off, and the sludge cleaning agent is discharged along with the engine oil. During engine operation, the high-temperature working environment, wear from the relative movement and friction of various surfaces, and the combustible mixed gases entering the crankcase from the cylinder can all affect the performance and quality of the engine oil.
