What is an Oil Filter and How Does It Work?

By having an understanding of what exactly is an oil filter, you will be convinced that it is indeed a must-have. In a nutshell, an oil filter is basically responsible for the removal of contaminants in the oil of the vehicle’s engine. It helps to keep the engine clean and free from impurities that could negatively affect its overall performance.

The exterior of an oil filter is made of a metal can. It has a gasket that seals it on the surface of the engine. The base plate, on the other hand, holds the gasket. It is built with perforations surrounding the gasket. Inside the can, there is a filter. The material used will vary from one model to another. More often than not, it is synthetic fiber. When the engine pumps, oil will be directed to the filter. Once it enters, the filter media blocks the dirt before the oil is sent back to the engine.

Types of Oil Filters

To become a wise buyer and find one that is suitable for your needs, it is important to become familiar with the different types that are available, which include the following:

Mechanical Oil Filter: The filter media that you can find in this type is made of cotton waste or pleated filter paper. This is where the contaminants are suspended to make sure that they won’t reach the engine oil. When the material builds up, the flow of oil to the engine becomes restricted.

Cartridge and Spin-On Oil Filter: The first oil filters were cartridge type. There is a filter media that is contained in a permanent housing. It later evolved to become a spin on filter. The housing is self-contained while the filter medium is replaceable. This makes it easier to change the filter, which is also cost-effective in the long run.

Magnetic Oil Filter: In this type, there is an electromagnet or magnet to suspend the contaminants. With this, you just have to clean the magnet to get rid of the particles that have been collected. After this, the filter medium can be reused.

Sedimentation Oil Filter: Also known as gravity bed oil filter, it suspends impurities that are heavier compared to the oil of the engine. The gravity makes it possible for the collected particles to stay at the bottom.

Centrifugal Oil Filter: This is one type that falls directly under the sedimentation oil filter. Nonetheless, the main difference is that instead of relying on gravity, it uses centrifugal force from a rotating device to eliminate the contaminants.

Signs that You Need a New Oil Filter

Pay attention to the following things and take them as a warning that the oil filter needs to be replaced. If they are not replaced as needed, they will be useless and this is going to compromise the performance of the vehicle.

Poor Performance of the Car: One of the first things that you will notice is that the car will not accelerate as it normally would. The accelerator may also feel wrong.

Overheating: If the engine overheats, one of the reasons would be a faulty oil filter. The contaminants can build up on the engine, which will affect heat conductivity. This causes the temperature to rise.

Leaking: When there is oil leaking out of the vehicle, this is an obvious sign that there is something wrong. This means that the filter is no longer able to adapt to temperature changes.

Engine Light Turns On: Any responsible driver would know that the engine light turned on is an indication of a problem. This could be because of the buildup of contaminants that could no longer be strained by the oil filter that is currently installed.

Weird Sound: If you hear a metallic sound coming out of the engine, this could also be because of the oil filter. The filter is probably clogged, which can be because of its old age.

Essential Considerations when Choosing the Best Oil Filter

While there are many options that are available on the market, there should be no excuse to pick just any product. To help you out in narrowing down the possibilities, here are some of the most important things that you need to consider:

Ease of Use: It is important to choose an oil filter that is user-friendly. This means that the assembly should be free of complications. You do not need to pay a mechanic to have it installed on your engine.

Durability: The oil filter must be able to withstand the external elements that could possibly speed up damage. For instance, it will be good if it has the ability to resist corrosion

Compatibility: One of the first things that you have to do is to check your vehicle and the requirements for the oil filter. In some cases, the oil filter is manufactured exclusively by the car company. See to it that the size and the model will be appropriate.

Filter Media: This is the part that directly screens the contaminants. Most of the modern oil filters come with pleated paper and a synthetic medium.

Anti-Drain Back Valve: This is a feature that is common in the modern models of oil filters. This will make sure that the oil will not flow backward to the filter. It also helps in keeping the engine lubricated.

Wrap Up

With the best oil filter, the performance of your vehicle can be improved significantly. It is an investment that you will need to get rid of the contaminants that could possibly compromise performance. The options will be endless, but this should not be an excuse for you to choose just any filter. Instead, keep an eye on the products above and for sure, you will not have regrets.
