120,000 kilometers without changing the gasoline filter?How often is the gasoline filter replaced?

There are two types of gasoline filters, one is a built-in gasoline filter, and the other is an external gasoline filter. The built-in gasoline filter is only used in a small number of models, and its replacement cycle is longer, generally in ten. The replacement is about 10,000 kilometers, and it is more troublesome to replace, and the gasoline pump needs to be disassembled to be replaced, and the labor costs are more expensive. The external gasoline filter is used by most vehicles and has a short service life, usually every 10,000 to 20,000 kilometers, and needs to be replaced frequently.

If the built-in gasoline filter element is not replaced for 120,000 kilometers, it is actually okay, but it must be replaced in time to avoid adverse effects. And if the external gasoline filter element is not replaced for 120,000 kilometers, it has already caused a great impact. Because it has not been replaced for a long time, the gasoline filter element is already in a dirty state and cannot normally filter the gasoline that is about to be burned, which will cause the engine to produce a large amount of fuel. Carbon deposits shorten the service life of the engine.

The hazards of fuel filter not replaced for a long time

1. It will be difficult to start up, and it needs to be started multiple times.success, Even need to add a little throttle to start;

2. It may cause sudden flameout during driving, which may cause certain safety hazards;

3. In the case of rapid acceleration, the vehicle will have insufficient power and slow speed at the start;

4. The gasoline filter element is blocked, causing the fuel supply pressure to drop and the working pressure of the gasoline pump to increase, which will eventually cause the gasoline pump to be damaged;

5. The gasoline cannot be filtered completely, resulting in a large amount of carbon deposits in the engine after combustion, and knocking will also occur.

Therefore, if it is an external filter, it must be replaced in time so that it can normally filter the gasoline that is about to be burned, so that the quality of the gasoline is higher, and it can better participate in the combustion and provide sufficient power for the vehicle.
