Harm of engine internal cleaning agent

Engine internal cleaner is useful, but its effect is relatively limited.

The cleaning agent inside the engine can clean the residual dirty sludge in the engine oil channel, and at the same time, it can also clean the carbon deposit in the piston ring and ring groove to a certain extent, which has practical maintenance effect on the engine. However, due to its short residence time in the engine lubrication system and the defects of this disassembly-free cleaning method, the role of internal cleaning agents in the engine is relatively limited. Engine cleaning agents are mainly divided into engine oil version and fuel oil version according to components and adding methods. The fuel version is commonly used by car owners. It is poured through the fuel filler, mixed and diluted with fuel, and then burned in the engine to purify it.
