Fuel system cleaning, the name sounds very tall, but there are mainly two places for actual cleaning – the fuel rail and the fuel injector. The oil tank, oil circuit and even the oil pump are all very thick and can’t be blocked by themselves.
In the traditional car repair process, special “cleaning agents” are also used to clean various parts, such as oil-stained gears, casings, pipes, etc. After washing, it will look like new, you must be wondering what this magical cleaning agent is, yes, it is gasoline.
Therefore, in the process of normal car use, with the flow of gasoline, the fuel system itself is constantly being cleaned, no matter it is tens of thousands of kilometers, as long as the quality of the gasoline added is qualified, there will be no contamination.
What if the quality of the gasoline is not up to standard? Generally speaking, the fuel circuit problem caused by the substandard gasoline quality is mainly due to the large amount of impurities, which will cause the fuel injection nozzle to be blocked, which will eventually lead to unstable fuel injection volume, which in turn affects the combustion. However, before the impurities enter the oil circuit system, they will first pass through the fuel filter. According to the manufacturer’s maintenance manual, the fuel filter needs to be replaced regularly. As long as it is properly maintained, the oil circuit caused by impurities can be avoided.
In summary, the fuel system does not need special cleaning if there is no problem. Even if cleaning is required, focus on cleaning the fuel injector.
