Is Engine Cleaning Oil Harmful to the Engine?
2 Answers
No, it is beneficial and not harmful for vehicles that have been driven for a long time without cleaning and maintenance. Below is an introduction about engines: Introduction: An engine is a machine that can convert non-mechanical energy into mechanical energy. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. External Combustion Engine: An external combustion engine means that the fuel is burned outside the engine. Internal Combustion Engine: An internal combustion engine, or reciprocating piston engine, differs from an external combustion engine in that the fuel is burned inside it. There are many types of internal combustion engines, with common gasoline and diesel engines being typical examples.
I've been driving for over 20 years. Engine flush oil itself isn't harmful, the key is how to use it. Add a bottle during regular maintenance - it dissolves sludge and carbon deposits, keeping the engine interior clean for smoother operation. For older cars like mine, I do one flush before annual long-distance trips. It improves oil fluidity and even reduces fuel consumption slightly. But misuse like frequent flushing or using inferior products can be problematic. The strong solvents may damage the newly formed lubricating film of fresh oil. While not immediately apparent, prolonged use increases wear and may lead to major repairs. Always follow the manual - synchronize it with oil changes, doing one flush every 30,000-50,000 km is sufficient. Also remember to idle for a few minutes after flushing to discharge residues, ensuring safety and harmlessness.
