Why Oil Filter Is Important in Car

Oil filters play a vital role in keeping your car engine clean and running smoothly. Over time, oil gets dirty and can start to clog up your engine if it isn’t filtered properly. That’s why it’s important to change your oil filter regularly – typically every 5,000 miles or so. In this article, we’ll discuss why oil filters are important and how they work to keep your car engine running smoothly.

What is an oil filter and why is it important?

An oil filter is a device that helps remove impurities from engine oil, transmission oil, lubricating oil, or hydraulic oil. Oil filters are used in many different types of machinery. Internal combustion engines and transmissions, for example, need clean oil to function properly. Hydraulic systems also rely on clean oil to operate correctly.

Oil filters play an important role in keeping machinery running smoothly and efficiently. By removing contaminants from oil, they help extend the life of engine and transmission components. They also help improve fuel economy by allowing engines to run at peak efficiency. In short, oil filters are an essential part of any car’s maintenance routine.

How often should you change your oil filter?

Your car’s oil filter protects your engine by trapping contaminants that could damage it. Over time, the filter can become clogged with dirt and debris, which is why it’s important to change it regularly. How often you should change your oil filter will depend on your car’s make and model, as well as your driving habits. However, most experts recommend changing it every 5,000 miles or so.

What happens if you don’t change your oil filter?

If you don’t change your oil filter, the oil in your car will eventually become clogged with dirt and debris. This will cause your engine to work harder, which will lead to decreased fuel efficiency and increased wear and tear on your engine. In extreme cases, not changing your oil filter can even cause your engine to seize up. So, be sure to change your oil filter according to the schedule recommended by your car’s manufacturer.

How to change your oil filter

It’s important to change your oil filter regularly to keep your car running properly. Here’s a quick guide on how to do it:

1. Locate the oil filter. It’s usually located near the engine, often on the side of the block.

2. Unscrew the old filter and remove it. Some filters can be difficult to remove, so you may need an oil filter wrench.

3. Clean the area around the filter housing with a clean rag. This will help ensure a good seal when you install the new filter.

4. Install the new filter and screw it on tight. Be careful not to over-tighten it, as this can damage the housing.

5. Check for leaks and then start up your engine to make sure everything is working properly.


Oil filters are important in cars because they help to remove contaminants from the oil before it circulates through the engine. This helps to keep the engine clean and running smoothly. There are a variety of different types of oil filters available on the market, so it is important to choose one that is compatible with your car. Be sure to check your owner’s manual for recommendations on which type of filter to use.
