Does Engine Cleaner Harm the Engine?
1 Answers
Engine cleaner does not harm the engine. However, excessive use or leaving large residues inside the engine should be avoided. When low-quality engine oil is used or maintenance is neglected for an extended period, sludge, carbon deposits, and other harmful substances can accumulate inside the engine. Engine internal cleaner is a maintenance product designed to keep the engine clean, remove oil deposits, and reduce wear. It primarily consists of mineral oil and detergent dispersants, with the latter accounting for a larger proportion. When used correctly, there is no harm. However, improper operation leading to excessive residual detergent dispersants inside the engine can affect the lubrication and maintenance performance of the new oil after servicing. The cleaned sludge may also clog the oil filter, and in severe cases, it can cause abnormal wear inside the engine cylinder, leading to issues like engine noise or even engine seizure. Therefore, it is crucial to follow proper operating procedures. The standard method for using engine internal cleaner is as follows: After the engine reaches normal operating temperature, add the cleaner and run the engine for 3 to 5 minutes. Then, completely drain the used oil containing the cleaner. If necessary, add an appropriate amount of oil to run the engine again and drain it thoroughly. Finally, add new oil.
