Do I need to change the oil filter when servicing the oil?

Release Time:

Jul 24,2023

Automobile oil maintenance is periodic, and the oil must be changed when the number of kilometers is reached or when the time is reached. So why change the oil filter at the same time as the oil change?

First of all, what is the role of machine filtration?

Automotive mechanical filters are also called "oil filters". The function of the mechanical filter is to filter the impurities in the oil flowing in the lubrication system. After the engine has been running for a period of time, some impurities will be produced.

These impurities are mainly divided into two categories: one is metal debris worn by engine parts during operation; the other is black muddy organic matter (carbon deposits) produced by chemical changes in engine oil at high temperatures during engine operation. These impurities get mixed into the engine oil and move with the engine oil in the lubrication system.

So, must the oil filter be replaced at the same time as the oil maintenance?

Yes, it must be replaced. If the engine filter is not replaced, about 25% of the contaminants in the old engine filter will re-enter the oil circulation, which will not only increase the chance of engine wear, but also reduce the performance of the new oil. Therefore, when changing the engine oil, the filter must be replaced, which is also beneficial to prolong the service life of the engine.

Since the filter needs to be replaced every maintenance, is it possible not to change the oil?

No, the oil will lose its original performance after being used for a long time. When the oil is lubricated, it acts as a cooling agent. In fact, to put it simply, the oil filter can only filter out the metal debris mixed in the oil, and it is useless to the dust inside! Therefore, we need to change the oil filter regularly, and also need to change the oil according to the maintenance manual!

How to choose an air filter

The air filter is the most important part of the three major filters that protect the machine, because the quality of the oil and fuel is controllable, the quality of the air is the most uncontrollable, and the impurities in the air are the types that need to be properly filtered .

The Lungs of Your Engine - How an Air Filter Works

An engine needs two raw materials to work: gasoline and air. Gasoline is purchased by us, added to the fuel tank of the car, filtered through the oil supply system, and then sent to the combustion chamber of the engine to mix with air for combustion. And the air does not need to be purchased, just take it directly. How does the air enter the engine? Still need to filter?

Misunderstandings and identification methods of air filters

The task of the air filter is to filter the suspended particles in the air entering the cylinder to reduce the wear of the cylinder, piston and piston ring. Of the three media required for the engine to work, air has the largest volume and comes from the atmosphere. If the air filter cannot effectively filter the suspended particles in the air, the lighter one will accelerate the wear of the cylinder, piston and piston ring, and the heavier one will cause the cylinder to be strained and shorten the service life of the engine.

How often should the hydraulic oil filter be replaced?

The hydraulic oil filter element is used in the hydraulic system to filter out solid particles and colloidal substances in the working medium. As well as filtering out solid impurities mixed from the outside or generated inside the system in various oil systems, it can effectively control the pollution degree of the working medium and protect the normal operation of mechanical equipment. It is an indispensable part of the pipeline series for conveying medium .
