Is Fuel System Cleaning Necessary?
2 Answers
Whether the fuel system needs cleaning depends on the vehicle's condition and mileage. If the vehicle is in good condition without major issues, cleaning is unnecessary. For vehicles with over 60,000 kilometers, a cleaning may be beneficial. Generally, using fuel additives for cleaning is sufficient, which involves adding the fuel additive to the fuel tank. It is advisable to choose fuel additives with PEA formulation. The primary reason for cleaning the fuel system is that gasoline inherently contains olefin-like substances and gums. If the fuel system is not cleaned for an extended period, the fuel injectors may become clogged, leading to poor combustion, reduced power, increased carbon deposits, higher fuel consumption, and other related issues. Additionally, carbon deposits and deposits can cause the intake valves to not close tightly, resulting in decreased cylinder pressure and even backfiring.
I think fuel system cleaning is quite necessary, especially after driving in the city for a long time or using low-quality gasoline. The fuel injectors and valves are prone to carbon buildup, which can cause the car to lose power and increase fuel consumption. I've been driving for over ten years and clean the system every 20,000 kilometers. After each cleaning, the car accelerates more smoothly and the noise level decreases. If you have good driving habits, you can reduce the cleaning frequency. However, if you notice unstable idling or jerky starts, it's time to get it checked. The cleaning cost is relatively low, usually just a few hundred yuan, which is a cost-effective way to prevent more expensive engine problems. Don't wait until the car breaks down to regret not maintaining it. Early maintenance keeps the car in good condition.
