What will happen if the car filter is not replaced for a long time?

An air filter is also called an air grid or air filter. Its function is to filter out dust and impurities in the air, improve the purity of the air in the combustion chamber, and thus ensure the complete combustion of fuel. Air filters are generally required to be replaced every 10,000 to 15,000 kilometers. If the air filter is not replaced for a long time, a lot of impurities will adhere to the surface of the filter, causing blockage. When the filter is clogged, it will reduce the intake air volume of the engine, causing changes in the air-fuel ratio inside the engine. This will affect the combustion process, leading to carbon deposits inside the engine, unstable idle speed, reduced power, and increased fuel consumption.

The oil filter is also called the oil strainer or oil filter. Its function is to filter impurities in the engine oil, improving its cleanliness and lubricity. The oil filter element is generally replaced after the vehicle has traveled about 5,000 to 10,000 kilometers. Each time the engine oil is changed, the oil filter element should be replaced. If the oil filter element is not replaced for a long time, it will lead to deterioration of the oil, reduced lubrication effect, accelerated wear of components and increased carbon deposits.

The air conditioning filter is also known as the air conditioning grid, cold air grid or pollen filter. Its function is to filter out impurities, fine particles, pollen, bacteria, industrial waste gas and dust contained in the air entering the carriage from the outside. It provides a good air environment for the passengers in the vehicle, protects their physical health, and also prevents the glass from fogging up. The air conditioning filter element is generally required to be replaced every 10,000 kilometers of vehicle travel. If it is not replaced for a long time, it will lead to an increase in bacteria in the air inside the cabin, unpleasant odors, and affect the health of passengers.

The fuel filter is also called the gasoline filter, gasoline filter element or diesel filter. Its function is to filter the fuel (gasoline and diesel) needed by the engine, prevent metal impurities, water, organic matter and other substances in the fuel from entering the cylinder, so as to avoid engine wear and blockage of the fuel system pipelines. Gasoline filter elements are divided into two major types; One type is the inline type and the other is the built-in type. The built-in gasoline filter element is installed inside the gasoline pump of the fuel tank. The in-line gasoline filter element is generally recommended to be replaced after the vehicle has traveled about 20,000 to 30,000 kilometers. The built-in gasoline filter element does not need to be replaced as long as there is no problem with the gasoline pump. On the one hand, it is because its design structure is much more complex than that of the in-line gasoline filter element, so the maintenance cost will be much higher. If the gasoline filter element is not replaced for a long time, the car will have the following phenomena:

1. The engine idles and shakes
2. When stepping on the accelerator, the power starts up rather slowly
3. The car has difficulty starting
4. Increased fuel consumption
5. The fuel pipeline is clogged

Regular inspection and replacement of car filters are crucial for extending the service life of vehicles and safeguarding the health of car owners.
