How Often Should Fuel System Cleaning Be Performed?

[ClaytonFitz]

Automotive fuel system cleaning is recommended every 30,000-40,000 kilometers. The frequency may be adjusted based on driving conditions, road environment, mileage, and local fuel quality—especially if carbon buildup tends to form easily. Below are common fuel system cleaning methods: 1. Direct Fuel Additive Injection: The simplest method involves adding a fuel system cleaner directly into the fuel tank. High-quality additives not only improve fuel efficiency but also enhance engine performance, maintain engine health, and remove carbon deposits. 2. Intravenous Cleaning ("Drip Method"): This requires suspending a bottle-shaped device above the engine, filling it with cleaning solution, and channeling it into the engine via tubing to dissolve carbon buildup. 3. No-Disassembly Machine Cleaning: Some systems use specialized no-disassembly cleaning equipment that connects to the engine's fuel supply and return lines through dedicated adapters, creating a closed-loop cleaning cycle.
