Is It Necessary to Clean the Fuel Injector? How Often Should It Be Cleaned?

[VonIsabella]

It is necessary to clean the fuel injector, and it is recommended to clean it every 40,000 to 60,000 kilometers. Below is relevant information about fuel injectors: 1. Abnormal Symptoms: Carbon buildup in the fuel injector can lead to poor performance, resulting in accelerated wear of the cylinder and piston rings. This can cause issues such as unstable idling, increased fuel consumption, lack of acceleration power, difficulty starting, and excessive emissions. If not cleaned in time, the fuel injector may become clogged, and in severe cases, it can damage the engine. 2. Cleaning Methods: Cleaning the fuel injector should be done at a professional repair shop or a 4S store. If cleaned at a 4S store, they usually recommend a full set of cleaning services, which includes fuel system cleaning, covering the fuel injector cleaning. This is typically done using a drip method, where a bottle-shaped tool is hung above the engine, and the cleaning agent is poured into the tool. The cleaning agent is then introduced into the engine through a tube to remove carbon deposits. If the fuel injector is cleaned separately at an external repair shop, the cost is relatively cheaper.
