Can gasoline additives really help the engine clean up carbon deposits?

Gasoline additives are carried by fuel, which means that wherever the fuel passes, it can play a cleaning role. First of all, the fuel nozzle can definitely play a cleaning role. After all, the fuel is sprayed from the fuel nozzle. Secondly, the combustion chamber and piston can certainly play a cleaning role. In any case, the combustible mixture will eventually be ignited in the combustion chamber.

As for whether the carbon deposit on the valve can be cleaned up, it depends on the fuel injection mode of the engine. If direct injection is used in the cylinder, it cannot be cleaned. If manifold injection is used, it can play a cleaning role.

Matters needing attention in the use of gasoline additives:

1. In automobile maintenance, changing the oil, oil filter and air filter regularly is listed as a routine maintenance item in the after-sales maintenance manual. Various additives such as engine cleaner and gasoline cleaner are recommended maintenance items.

2. Most manufacturers don't require car owners to use these products, and they don't clearly indicate how long the vehicle needs to use additives. They will only recommend it to the owner when the maintenance master checks and judges that the vehicle needs cleaning.

3. Taking gasoline additives as an example, the composition of fuel additives from different manufacturers is quite different. Although they all contain a certain amount of detergent, manufacturers will selectively add rust inhibitors, emulsion inhibitors, bio-hydrogen, active agents, bio-enzymes, oil-saving agents and carrying oil, and their composition and content are determined by the manufacturers themselves.
