Car filters are required to keep the vehicle running in smooth condition. This is because they keep out all the dust and contaminants from the engine and other parts of the car so that they don’t affect its efficiency.
There are four kinds of filters, i.e., engine air filter, cabin air filter, oil filter, and fuel filter. The oil filter is used in cars, ships, air crafts, etc. to clean their oil. Contaminated oil damages the mechanical parts of the engine and reduces its life. This is why it is important to use a high-quality filter.
There are different types of oil filters, but the most common type is the mechanical oil filter and this article reviews the best oil filters for cars. Have a look!

Top 10 Best Oil Filters For Car In 2021 Reviews
1 K&N Motorcycle Oil Filter KN-138
K&N has been making high-flow filters for over fifty years. The KN-138 is a multi-oil filter that can clean out all oil brands and types. Its service vehicle type is all-terrain vehicles that are designed for use on rough roads.
It uses synthetic blend filtration media. Therefore, it can be used with oil types that include synthetic, petroleum-based, blended oils, and racing oils. It has AMA (American Motorcyclist Association) and MotoAmerica approval for racing. There is a 7mm hex nut that makes it easier to install and remove the filter.
The canister has heavy-duty construction and is designed to withstand high flow rates of oil. This is why this filter can handle heavy-duty applications and still clear out large particles from the oil. This makes it suitable for terrain vehicles that mostly travel on rough roads.
It uses O/E specifications. Therefore, it easily fits into the vehicle in place of the original filter. Its heavy-duty construction works under extreme conditions of pressure and temperature.
The anti-drain back valve of the filter prevents dry starts. Dry start happens when you start your engine, and the oil does not fully lubricate the system. The engine starts damaging If it goes too long without oil. The anti-drain back valve keeps the oil from getting back into the crankcase when you shut down your engine; hence no dry starts.
This K&N oil filter is mainly made for Suzuki vehicles.
- Uses wrench off nut for easy removal.
- It works with all oil types.
- Has a heavy-duty canister for protection.
- It can handle exceptionally high flow rates.

Micron is also known as micrometer, and it is the smallest unit for length measurement. It is one-thousandth of a millimeter and one-millionth of a meter. This unit determines the length of contaminants in the oil. Filters will have different performance for different sizes of contaminants.
The filter changing intervals are according to the manufacturer’s recommended periods. The canister is sturdy and durable. It can handle more than the normal operating pressure of the system. Therefore, it works just as well in extreme conditions.
There is an enhanced nitrile gasket, which prevents any leaks. Enhanced nitrile is basically a rubber that makes things like adhesives, sealants, floor mats, etc. This rubber is highly resistant to oil, fuel, and other chemicals.

Best Oil Filters For Car Buying Guide
Oil filters are installed in the vehicle’s engine, and, like all other parts of the engine, they play an important role. With oil filters, the engine’s life and consequently its performance will decrease significantly and faster than normal.
Particles such as dust, metal bits, carbon, and other things get into the engine and the oil over the course of its use. Without the use of a good filter and periodic filter change, these particles will cause rust and perhaps cracks to the engine.
It is, therefore, necessary to choose the right type and quality of the oil filter according to the vehicle you drive.
Every filter is not compatible with all cars or motorcycles. That is because the engine design of the vehicle varies from manufacturer to manufacturer. The filter and its casing have to fit in perfectly and not be loose. Otherwise, there will be leaks, and the performance will be lower than expected.
The original filters like Motorcraft filters are made by car manufacturers themselves and are designed only for their vehicles. But when the original filter runs out, and you need a replacement, it is not necessary to use the company recommended one.
There are manufacturers that make aftermarket filters. The main thing you have to keep in mind when using them is that they follow OEM standards. If they do, then they will say so on their package. These filters do not h ave limitations according to specific companies but can be work with a range of different cars.
The media of the filter has a protective casing. It uses a combination of different elements. This depends on the manufacturer. All the different types of materials used have their own advantages. This media is what actually filters and traps the contaminants from the oil and keeps them from entering the engine.
There are three basic types of media, i.e., cellulose, synthetic, and micro-glass. The filters can use a combination of these as well or add some other proprietary material in the blend, but these are what you will mostly see.
Cellulose is the most abundant organic polymer on earth and is most common in the making of paper. It traps particles in the random matrix of the cellulose fibers.
Synthetic filters last longer than cellulose and can trap small particles easily. They give the best results when used with synthetic oil.
Microglass works with a combination with other materials. It gives a large surface area for trapping the particles. It has high retention efficiency because of its fine mesh that can last as long as two to five years.
The grade or efficiency of the oil filter tells its ability to trap particles. It is given in percentages, but the percentage tells only half the story and the other half is the size of particles it can trap.
If the product says 99% efficiency for 25 microns, it does not necessarily mean it will give the same results for smaller or larger particles. Still, on most high-quality filters, you will see a rating that is greater than 90%. The efficiencies are mostly for 20, 25, or 30 microns.
Lastly, the filter capacity is the amount of oil it can hold at a time. To be more accurate, it is the amount of debris the filter can hold before it starts clogging, and the bypass valve opens. When the bypass valve opens, contaminated oil reaches the engine, which means it is time to change the filter.
This capacity has the unit of grams, e.g., a filter might be able to hold 14 grams of particles before it starts clogging. 13 or 14 grams is what most vehicles require.
All these products are chosen because they are the best oil filters for cars, but our best pick for oil filters for cars is the KN-138 filter. That is because it has extensively gone through testing for extreme conditions and provides a consistent flow rate. It does not work with one but all synthetic, conventional, and blended oils. This filter is also easy to remove and install and is uses a high-quality, sturdy case.
Different oil filters are for different types of oil and different types of vehicles. But in all conditions, they keep out dust, sand, carbon, metal, soot, and other things from the core parts of the engine. Just like engine air filters, it makes sure the combustion process and engine performance are at their maximum.
