Is engine cleaning agent useful? Is engine cleaning agent necessary?

I believe that when many friends go to the 4S shop for maintenance, they must have been recommended by the after-sales receptionists for the engine cleaning project. This is a project for cleaning the engine lubrication system through engine cleaning agent.

But many friends who don’t know much about the engine may have questions. Is this engine cleaner useful? Is it necessary to use it to clean the engine?

Are engine cleaners useful?

Useful, but the effect is relatively limited.

The engine cleaning agent can clean the dirty sludge remaining in the engine oil passage, and at the same time can clean the carbon deposit in the piston ring and ring groove to a certain extent, which has a practical maintenance effect on the engine. However, due to its short time in the engine lubrication system, coupled with the shortcomings of this no-disassembly cleaning method, the effect of the engine cleaning agent is relatively limited.

Is it necessary to use engine cleaner for cleaning?

Is necessary.

As the engine is working, the high temperature working environment of the engine; the wear caused by the relative movement and the operation of the friction surface; and the combustible mixture from the inside of the cylinder into the crankcase will affect the performance of the oil. Quality has a certain impact. When the performance and quality of the engine oil decrease, its ability to clean the engine oil passage will also decrease, which will eventually lead to the accumulation of sludge in the engine lubrication system, and even block the oil passage in severe cases. Therefore, the engine lubrication system needs to be cleaned regularly.

Although the effect of the engine cleaning agent is relatively limited, due to its convenient use and low cost, as long as it is used regularly, the engine performance can still be greatly improved. At the same time, almost all 4S shops currently use this method to clean the engine lubrication system.
