Is Engine Cleaner Useful?
2 Answers
Engine cleaner is useful, but its effectiveness is relatively limited. Engine cleaner can remove residual sludge from the engine oil passages and, to some extent, clean carbon deposits from the piston rings and ring grooves, providing practical maintenance benefits for the engine. However, due to its short retention time in the engine lubrication system and the inherent limitations of this no-disassembly cleaning method, the effectiveness of engine cleaner is relatively limited. Additional information: Reasons why the engine lubrication system requires regular cleaning: During engine operation, wear caused by the relative motion and friction of various moving surfaces, as well as the combustible gas mixture entering the crankcase from the cylinders, can affect the performance and quality of the engine oil. When the performance and quality of the engine oil decline, its ability to clean the engine oil passages also decreases, eventually leading to sludge buildup in the engine lubrication system and, in severe cases, even clogging the oil passages. Therefore, the engine lubrication system needs to be cleaned regularly.
As a veteran driver with 20 years of experience, I can say engine cleaners are indeed useful, but it depends on your car's condition. After regularly using cleaner on my engine, I clearly feel smoother acceleration because reduced carbon deposits allow more complete fuel combustion, and idle vibration disappears. This product suits well-maintained vehicles, not those with serious malfunctions. I recommend using it every 20,000 km, choosing reputable brands - don't save dozens of yuan on cheap products that might damage pistons or fuel lines. Remember, it's just an auxiliary tool; real maintenance requires combining oil changes and filter replacements. Driving habits matter too - avoid frequent short-trip start-stops to prevent carbon buildup. Used correctly, cleaners save money and time while extending engine life.
