What are the "three filters" that cars replace? Why do we need to replace the "three filters" regularly?

Regular car maintenance is an important maintenance work to ensure the normal operation of your car. Routine maintenance mainly involves replacing lubricating oil and "three filters", etc. The three filters refer to: fuel filter (if it is a gasoline engine, it is a gasoline filter; if it is a diesel engine, it is a diesel filter), oil filter, and air filter.

Why do cars need to replace filters?

1. The fuel filter is the "kidney of the engine". Its main function is to filter water and impurities in the fuel and provide reliable "oxygen materials" for the engine.

2. If the oil filter is not replaced for a long time, a large amount of impurities such as carbon, colloid, sludge, and metal wear powder will be produced in the oil during the operation of the engine. If it is not filtered, it will cause the wear of engine parts to increase.

3. If the air filter is not replaced for a long time, the air filter filter paper will absorb too many impurities, which will cause poor air intake or blockage, resulting in insufficient oxygen supply, black smoke from fuel combustion, and engine weakness.

Therefore, in order to ensure the good operation of the engine, it is very necessary to replace the car filter regularly.
