Here’s everything you need to know about car oil filters.

What is its function?

The oil filter of our car is in charge of protecting the mechanics of the car, filtering what would be the lubricant in order to clean it from any kind of impurities or dirt. 

These types of soiling could become: 

  • Charcoal.
  • Metal powder. 
  • Dirt, etc… 

These same particles could float into the lubrication circuit of our car’s engine. 

It should be noted that these same particles are generally found in the residues that are generated by the combustion or friction of the different components and the possible wear and tear of the same.

This prevents these residues from somehow damaging some of the components inside the engine, so they are isolated in the filter itself.

By using what would be centrifugal force, the oil is mobilised by a rotating drum in order to displace any harmful particles onto a filter paper.

This type of car filter is most commonly found in large diesel engines. 

Sedimentation oil filter

The sedimentation car oil filter is designed to remove all types of contaminants that are present in the oil. 

Believe it or not, they are generally heavier than the oil itself, and are deposited in a small container with the help of gravity itself.

As a general fact, these car oil filters have two sections, which are:
