What does the car oil filter filter? Are there really iron pin impurities in it?
When driving on the open road, people rarely think about the complex mechanical devices in the engine compartment. The car oil filter is one of the most important components in the vehicle engine system. It is responsible for filtering impurities in the oil and protecting the engine from particulate matter and pollution. Let’s take a deeper look at what the oil filter filters and whether there are impurities such as iron pins in it.
First of all, the main function of the car oil filter is to filter impurities in the oil.
As the engine runs, the oil circulates inside the engine to lubricate, cool and clean. But as the use time increases, the oil may carry various tiny particles, metal chips and other impurities, which will have a negative impact on the engine. Therefore, the existence of the oil filter is particularly important. It can effectively filter out these impurities, maintain the cleanliness of the oil and extend the service life of the engine.
Regarding the iron pin impurities that may exist inside the oil filter, this is actually not impossible.
In some cases, wear or damage to engine parts may cause metal particles to enter the oil system. These metal particles may come from the friction parts inside the engine, such as pistons, cylinder walls, crankshafts, etc., especially when the engine is aging or the oil is not changed in time, this situation may be more obvious.
When the oil filter is used for a long time or when the oil change cycle arrives, some car owners will choose to remove the oil filter and cut it open to check whether there are impurities such as iron pins.
Although this operation has a certain reference value, it also needs to be treated with caution. Because the oil filter itself will filter out most of the impurities, but it cannot guarantee that all tiny metal particles are completely filtered out. In addition, cutting the filter to check may also cause oil leakage or other problems, so it is recommended to do it under the guidance of professionals or refer to the relevant operating manual.
In short, the unsung oil filter is our car’s guardian.
By diligently filtering contaminants and maintaining oil quality, this unassuming component makes a significant contribution to the overall durability and performance of our vehicle. The next time you change your oil, take a moment to appreciate the critical role of this unsung hero of the automotive world.
