How many kilometers does the new family car need to drive to clean the throttle?

The frequency of throttle cleaning depends on the following two points:

1. How long the throttle will get dirty depends on the quality of the air filter, the brand and quality of the engine oil, the condition of the driving section, the temperature, the working temperature of the engine, driving habits and so on.

2. Even for individuals, it is impossible to determine the time to clean the throttle valve with a fixed number of kilometers. The interval between cleaning the throttle for the first time in a new car is the longest. Later, due to the continuous condensation of oil and gas in the crankcase ventilation pipe and intake port, the cleaning frequency will increase, and different weather conditions will also affect the dirty speed of the throttle.

Therefore, under normal circumstances, the 4S shop will advise the owner to clean it once every 20,000 kilometers. Of course, the situation of different models is different, and the throttle of some cars is easy to get dirty. It is not uncommon to need cleaning when it is seven or eight thousand kilometers. There is no strict limit on the frequency of cleaning the throttle, which has a lot to do with car habits and environment. If it is dirty, it should be washed. Phenomenologically, cleaning should be considered when the idle speed is unstable.

Failure to clean the throttle for a long time will lead to an error in the throttle opening, and air with impurities will enter the combustion chamber of the engine. These two results will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden feeling of throttle when driving, reduced power, and even difficult starting and increased fuel consumption.
