How Often Should the Engine Fuel System Be Cleaned?
2 Answers
Generally, the cleaning frequency should be once every 60,000 kilometers, and it can be appropriately adjusted based on your driving conditions and vehicle condition. Since fuel itself contains colloids, impurities, dust, moisture, etc., over time, sludge and other deposits will form in the fuel tank, fuel inlet pipes, and other areas, which can lead to blockages over time. Relevant information about car maintenance is as follows: Introduction: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Maintenance Scope: Modern car maintenance mainly includes the maintenance of the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.
I don't think engine oil system cleaning should be generalized. After driving old cars for so many years, I usually check every 40,000 to 50,000 kilometers to see if the oil has thickened or become dirty. In heavy city traffic, carbon buildup in the oil system is more likely, possibly requiring cleaning as early as 30,000 kilometers. Neglecting maintenance will lead to warning signs like louder engine noise or a sudden spike in fuel consumption. Using full synthetic oil can reduce sludge buildup. When cleaning is needed, find a reliable mechanic—safety first, don't attempt DIY fixes. Regular oil changes are more effective than frequent cleaning, saving money and hassle while significantly extending engine life.
