How often should the engine oil passages be cleaned?
2 Answers
The engine oil passages should be cleaned approximately every 30,000 to 50,000 kilometers. An engine is a machine that converts other forms of energy into mechanical energy. Engines can be categorized into: 1. External combustion engines: where fuel burns outside the engine; 2. Internal combustion engines: where fuel burns inside the engine; 3. Gas turbines: which generate high-pressure gas through combustion, using the high-pressure gas to rotate the turbine blades; 4. Jet engines: which directly generate thrust by expelling high-speed gas from the nozzle. Engines can also be classified by cylinder arrangement into: 1. Inline engines; 2. V-type engines; 3. W-type engines; 4. Horizontally opposed engines; 5. VR engines.
That's a great question. As a veteran driver who has been behind the wheel for decades, I believe cleaning the engine oil passages depends on actual driving conditions. If you frequently encounter heavy traffic in the city, it's best to clean them every 20,000 kilometers. For those who often drive on highways, you can extend the interval to 30,000-40,000 kilometers. Cleaning ensures smoother oil flow and prevents carbon buildup, otherwise the engine may suffer from wear and overheating. Make it a habit to check during routine maintenance—it saves hassle in the long run. Don’t clean too often (it’s a waste of money) or delay it too long (it shortens engine life). Pay attention to oil quality and change it regularly to reduce the risk of clogged oil passages. After all, your car is a companion—take good care of it, and it’ll serve you longer.
