Does Engine Internal Cleaner Harm the Engine?

[LeRhett]

Engine internal cleaner can harm the engine. The dissolving capability of engine cleaner is relatively strong. If the car owner uses engine cleaner to clean the engine too frequently, it may cause certain damage to the internal seals and cylinder block of the engine. If a large amount of engine cleaner residue remains inside the engine after cleaning, it can also affect the balance of the engine oil, degrading its performance. Engine cleaner can play a certain cleaning role when the vehicle's mileage is not high, the internal carbon deposits are not severe, and the accumulation of sludge and dirt is minimal. After cleaning, it can remove carbon deposits, sludge, and dirt, enhance the fluidity of new engine oil, reduce engine temperature and noise, improve lubrication performance, reduce wear, and extend the engine's service life.
