The potential harm of engine cleaners to the engine lies in their strong dissolving ability. If vehicle owners use engine cleaners excessively, it may cause damage to the engine's internal seals and cylinder body. Additionally, if a significant amount of engine cleaner residue remains inside the engine after cleaning, it can affect the balance of oil components, leading to degraded oil performance.
Engine cleaners are effective for vehicles with low mileage and mild carbon buildup and sludge accumulation inside the engine. When added under such conditions, they can have a cleaning effect by removing carbon deposits and sludge, improving the flow of new oil, lowering engine temperature and noise, enhancing lubrication performance, and reducing wear, thereby extending the engine's lifespan.
However, for vehicles with heavy dirt accumulation, the cleaning effect of adding engine cleaner may not be very noticeable. During the cleaning process, the re-release and circulation of dirt may lead to oil passage blockage, poor lubrication, or even bearing seizure. Therefore, vehicle owners should assess their vehicle's usage conditions before deciding whether to use engine cleaner.
In terms of engine maintenance, it's essential for vehicle owners to adhere to the maintenance schedule specified in their owner's manual and perform regular maintenance. Timely replacement or addition of engine oil is crucial, and if the filter shows signs of clogging, it should be replaced promptly to avoid internal contamination and accelerated engine wear.
