Is Honda carbon deposit cleaning agent useful?

Honda carbon cleaner is useful. Honda fuel additives can be mixed with fuel for combustion. Micro-nano clusters will be generated in the combustion process, and these micro-nano clusters will detonate to generate steam before or during combustion, which will play a cleaning role. It can help decompose and crush the deposits in the combustion chamber, dissolve the carbon deposits, and is more conducive to fuel combustion. The engine injector with in-cylinder direct injection technology will directly inject fuel into the cylinder, which is the practice of most Honda engines. When using fuel additives, the top of the engine intake valve will not be cleaned. In order to remove the carbon deposit above the intake valve, the engine must be disassembled to completely remove the carbon deposit.
