Can Fuel Additives Clean Carbon Deposits?
2 Answers
Fuel additives can clean carbon deposits. Fuel additives have a certain ability to clean carbon deposits, especially for minor carbon buildup, where using legitimate additives can achieve satisfactory results. The purpose of fuel additives is to address carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restore the engine to optimal working conditions, and compensate for some deficiencies in gasoline properties. They also enhance gasoline by improving atomization, reducing wear, protecting the engine, and lowering emissions. The functions of fuel additives include: 1. Removing carbon deposits from the vehicle; 2. Reducing abnormal engine wear; 3. Improving atomization efficiency; 4. Lowering vehicle emissions; 5. Extending the service life of the vehicle's engine.
Last time I tried using fuel additive to clean carbon deposits, the results were quite surprising. This stuff mainly relies on polyetheramine to dissolve the gum deposits on fuel injectors and intake valves, which does work well for soft carbon buildup that's just formed. After using it continuously for three tanks of gas, the engine vibration reduced, but I could still see black hardened deposits on the back of the throttle body. The mechanic said fuel additives are basically useless for carbon deposits on piston crowns, especially for older cars that have been running for seven or eight years. If you really want a thorough cleaning, you'd need to disassemble the engine for walnut shell blasting. Of course, it's quite suitable for new cars to prevent carbon buildup - I recommend adding a bottle of a major brand like Chevron TCP every 5,000 kilometers.
