Is the Carbon Deposit Cleaner Added to the Fuel Tank Effective?
2 Answers
Adding carbon deposit cleaner to the fuel tank is effective. The methods for cleaning carbon deposits are as follows: 1. Additive Cleaning (Fuel Additive): Additive cleaning involves directly adding the cleaner to the fuel tank to mix with the fuel. When the vehicle is started, the cleaner will enter the combustion chamber along with the fuel, and during this process, it will clean the carbon deposits inside the engine to a certain extent. 2. Drip Bottle Cleaning: Drip bottle cleaning, also known as no-disassembly cleaning, is a cleaning method currently promoted by 4S shops. This method uses a drip bottle to introduce the cleaner into the engine's intake pipe, where it is sucked into the combustion chamber along with the intake airflow. During this process, the cleaner will clean the carbon deposits in the engine's intake tract and combustion chamber. 3. Disassembly Cleaning: Disassembly cleaning involves removing parts of the engine where carbon deposits have accumulated for cleaning. Although this method provides the best cleaning results, it is labor-intensive and time-consuming, so most 4S shops do not offer disassembly cleaning services.
I've been repairing cars for over a decade and have seen many people use carbon deposit cleaners in their fuel tanks. These products do work, but their effectiveness is limited. They mainly help clean minor carbon deposits near the fuel injectors, improving gasoline atomization. However, they're not very effective against severe carbon buildup in areas like the combustion chamber and piston rings. Always read the product instructions carefully before use, as the mixing ratio is crucial. Initially, you might notice the throttle feels lighter and fuel consumption decreases slightly. But if the carbon deposits are too severe, large chunks might break off and clog the fuel lines. I recommend using it every 5,000 kilometers. Also, always choose reputable gas stations for refueling—it's better for your engine in the long run.
