The scientific name of fuel treasure is fuel additive. We usually use fuel additives with cleaning function. The main function is to clean the fuel nozzle and oil circuit, and by the way, it also has the function of cleaning the carbon deposit in the engine.
When the engine nozzle is in use, the gum in gasoline will remain in the nozzle, and the nozzle hole will be blocked by carbon deposit, which will lead to poor atomization effect of the nozzle, reduce engine power and increase fuel consumption, so we need to use fuel additives to clean the nozzle regularly.
