How Often Should Engine Cleaner Be Used?

[DiEliana]

Engine cleaner should be used once every two years. Cleaning the lubrication system, intake tract, and combustion chamber is essential. However, under normal vehicle operating conditions, engine cleaning is generally considered every 30,000 to 50,000 kilometers. When a car starts, especially during a cold start, the engine is highly susceptible to wear because the oil cannot provide immediate effective protection. Dirty oil can lead to insufficient oil pressure, causing hydraulic lifter valves to fail, which may result in engine noise, unstable idle, and reduced engine power. Internal cleaning is the key to engine maintenance, typically performed using a non-disassembly cleaning method during oil changes. The general procedure involves pouring professional engine cleaner into the oil filler port, mixing it with the old oil, idling the engine for 20 to 30 minutes, and then draining the oil.
