How often should the engine oil passages be cleaned?

[SanLola]

Engine oil passages should be cleaned every 50,000 kilometers, which can quickly restore engine performance after cleaning. An engine is a machine that converts other forms of energy into mechanical energy, including reciprocating piston engines, Stirling engines, steam engines, jet engines, electric motors, etc. The benefits of cleaning the engine include: 1. Preventing the mixing of old and new engine oil, removing sludge and oil films formed by old oil to avoid reducing the performance of new oil; 2. Improving engine efficiency, reducing noise, and decreasing fuel and oil consumption; 3. A clean engine lubrication system enhances oil flow, lowers engine temperature, and improves lubrication efficiency; 4. Preventing the engine from burning oil.
