Is it necessary to clean the fuel nozzle to clean the carbon deposit in the combustion chamber?

There is no doubt that the fuel nozzle is the component that has the greatest influence on the fuel combustion efficiency. Only a clean fuel nozzle can spray evenly atomized engine oil and burn it efficiently, otherwise it will reduce combustion efficiency and increase fuel consumption and emissions. The simple cleaning method is to add fuel nozzle cleaning agent additive to gasoline, which will slowly clean the fuel nozzle carbon deposit. We mainly need additives with reliable quality, otherwise it will affect the sealing performance of the oil circuit. I usually use American Ryan Bo, and every time I refuel, the ratio is 1000: 1.
