Best Oil Filters On The Market

The Best Oil Filters – Reviews and Comparison

Take the motor oil as the blood which maintains your car’s engine alive. As the oil circulates through the engine, it inevitably collects a variety of contaminants.

These contaminants can damage the engine and after a while, it will worsen its operation or in the worst case, it can break and stop working.

This is where the oil filter comes – it purifies the oil that goes through the engine, which preserves both the qualities of the oil itself and the proper engine operation.

That is why it is so important to replace the oil filter with every oil change. Oil change intervals must be strictly followed by the recommendations of the manufacturer but usually, they vary from 3 000 to 10 000 miles.

As the work of the oil filter is really significant for the entire operation of your engine we took time to speak with industry professionals and mechanics seeking their opinions and advice. After in-depth research, we have selected the best oil filters on the market for your car.

The Best Oil Filters Buyer’s Guide & Frequently Asked Questions

The Best Oil Filters On The Market

The reliability and life of your car’s engine are directly dependent on the quality of the oil filter. Now that you are already familiar with the best oil filters on the market, we should discuss the principles of oil filter functioning and the features that need to be considered when choosing it.

What is an oil filter function and why it is important?

The oil filters are located in any internal combustion engine. They remove harmful contaminants that reach the lubricating system from the environment or formed in the engine during operation.

Or in other words, the oil filter cleans the engine oil from microscopic dirt that affects engine performance.

What do oil filter and engine oil do?

  • Both the oil filter and engine oil work together in order to:
  • Extract the heat from the surfaces of engine components that are heated due to friction;
  • Clean the engine from dust, soot, metal particles that are formed during the operations of the engine;
  • Create an oil layer that prevents friction of contact surfaces;
  • Reduce engine noise

Specifications in the oil filter operation

The oil filter is used in severe conditions. It is constantly exposed to temperature changes caused by engine operation and chemical substances obtained by the hot temperatures of the oil.

The media from which the filter element is made must be resistant to thermal and chemical attacks in order to provide stable filtration flow of oils of different viscosity.

Oil Filter Anatomy

How to choose the right oil filter for your car?

  • The first and most important thing to do is to know the exact size and model you need for your car. You can do that by referring to the owner’s manual or calling the dealership. Another way to find it out is on the manufacturer’s websites. They usually have a section where you select the brand/ model/ year of your vehicle and the correct filter appears.
  • Pay attention to the efficiency of filter media. It must meet the technical requirements of your vehicle. The average oil filtration the filter must provide is about 10 microns. Well-cleaned oil prolongs the quality of life of the engine and its components.
  • Take into consideration the durability of the filter cap. The valves and seals are also very important components that must be of good quality.
  • Make sure the oil filter type is compatible with the engine oil you are going to use. We’ll discuss the different oil filter types below.
  • The brand matters. Do not go with the cheapest brand because, to be honest, the cost difference between a cheap and high-quality oil filter is not that significant. Spend those extra bucks for the better work of your engine. All the brands and oil filters that we have mentioned above are from the highest quality that you can rely on.
  • When purchasing an oil filter from the internet, only use trusted online stores like Amazon. Typically, they offer the best prices (even better than in the manufacturer’s websites and local stores), proper customer support and warranties.

Understanding the different types of oil filters

During the years, many different kinds of oil filters have been invented with some of them constantly improved and developed. In this section, we’ll list the most common ones nowadays with a short explanation so you can get a general idea.

Primary Oil Filters

The majority of automobile engine producers use primary oil filters. These kinds of oil filters also referred to as full-flow filters, filter 100% of the engine oil. Because it is crucial for them to function effectively in order to maintain the motor lubricated, the primary oil filters feature reduced flow restrictions.

In colder weather engine oil thickens and a restrictive oil filter might end up in destruction to the motor. Therefore, full-flow oil filters let minor pollutants to pass through them. Engine makers usually set up a fail-safe bypass valve if the media of the filters get very clogged.

In case the filter turns out to be clogged and will not let the engine oil to get to the motor, a special pressure mechanism is going to reroute the oil around the media to the motor so the lubricating process remains.

Secondary (Bypass) Oil Filters

Along with the full-flow oil filters, many engine suppliers usually setup secondary oil filters, also called bypass filters. This type of filters performs at a limited part of approximately one to ten percent of the engine oil and filter it prior to returning it back to the motor.

The bypass filters function separately of the full-flow oil filters and assist with eliminating extra, much smaller particles. This allows longer mileage intervals in between the oil changes.

Conventional oil filters

These types of filters are under the bypass filters category. Conventional filters clean the oil with plain cellulose membranes and they must be replaced a lot more regularly as they are used to stop smaller particles.

Magnetic Oil Filters

This type of oil filter uses a magnet or electromagnet to attract and collect iron particles when oil is passing through a magnetic flux area.

Thermal Chamber Oil Filters

Thermal Chamber Oil Filters clean the engine oil in order to remove contaminants and in addition increase their heat therefore particular debris in the engine oil burn off or become eliminated.

Centrifugal (Spinner) Oil Filters

Those oil filters function with a rotating movement in order to capture and keep the debris in the engine oil. Usually, the spinner filters are made of two sectors – a housing chamber and a membrane. Once the media becomes blocked, you just have to change it whereas the housing chamber stays functional. The base gasket is a crucial element of a centrifugal oil filter. This helps to avoid oil from leaking, however, it is not really sturdy and it is advisable to be checked by an auto technician at about every 3 500 miles.

How often to change the oil filter?

The change of oil is directly related to the change of the oil filter, whose task is to stop all contaminants such as unburnt fuel residues, oxidation products, airborne dust, or metallic particles. A jammed filter may cause the oil not to be cleaned but only injected under high engine pressure which will damage the vehicle.

Change your oil filter with every engine oil change. Oil change intervals depend on the type of oil you use and the manufacturer’s recommendations. See your owner’s manual or call a dealership for detailed information.

We recommend an oil and oil filter change at least once a year.

Here is a very straight to the point video on how to change your oil filter yourself:

Can I change oil without changing the oil filter?

Oil filters have a strictly limited resource and must be replaced with every oil change. Reusing an oil filter results in engine oil starvation and damage to the motor. Saving from an oil filter change can result in costs many times exceeding the value of the oil filter itself.

How do I know if my oil filter is bad?

There are several signs of oil filter failure that you need to be aware of if you want to prevent delayed change and damage to your engine.

Metal Noises

If it happens that you hear some unusual metallic sounds from your engine, most probably the oil filter is clogged and it can not supply proper oil flow to the engine. The metal noises that you hear come from the friction of the parts that have not been lubricated and you must stop the engine immediately.

Water in the oil

It is also possible to notice that oil is thinner or pale than it should. This is a sign of interacting with water. You can observe that by regular oil level checks on the dipstick.

Particles inside the oil

Check the level of your engine oil and leave a few drops on your fingers. Rub your fingers and see if there are some metal parts or particles. If you feel there are minor contaminates, then most probably your oil filter is clogged and needs a replacement.

Dirty/ Darker Exhaust Pipe

The clogged oil filter can be easily identified if you see dirty or darker parts on the back of your car and more specifically around the exhaust pipe area. In that case, a dark exhaust coming out from the car can be easily seen and smelled.

Reduced engine power

If you are trying to push the gas or accelerate faster and you notice the car is not performing as usual or in other words not responding to the gas pedal, this is another sign the oil filter is clogged. Stop the engine immediately and ask for the advice of an experienced mechanic.

Dropping oil pressure gauge

If you observe that the oil pressure gauge is dropping or the engine light is on, this is a sign of an oil pressure drop that may be caused by the clogged oil filter.


Take your time and choose your oil filter carefully. Before buying it, you need to read the technical details of your vehicle: even the highest quality oil filter is not insured by premature wear if used in inappropriate conditions.

Shop only from trusted stores like Amazon. Take into account our recommendations for the best oil filters, and your car will serve you impeccably.
