12000 km Do you need to clean the fuel injector?

10000 km or more, there is no need to clean the nozzle, because the carbon deposit has accumulated for a long time. As long as you refuel at a regular gas station for more than 10 thousand kilometers, there will be no carbon deposit in the fuel nozzle. Generally, the injector is cleaned once every 60,000 kilometers. Clean the throttle while cleaning the fuel injector. If it is a direct injection engine above 1.8L, it is necessary to clean the valve carbon deposit. Otherwise, it is ineffective to just clean the injector. More than 10,000 kilometers is just to change the oil, air filter and air conditioner filter, check the tires, check the lights and check whether the chassis screws are loose. Because more than 10 thousand kilometers have just been insured for the first time, there is generally no problem.
