As the oil runs through the engine it interacts with a lot of different parts. On its way, it picks up grit and particles of metal. These things contaminate the oil and make it dirtier over time. Once the oil reaches a certain threshold, it will lose its ability to properly lubricate and clean your car’s engine.
Most manufacturers advocate replacing your oil filter each time you change the oil in your car. You might have to change it after every 3,000 or 15,000 miles. But it actually depends on what kind of oil filter you’re using. So it makes a lot of sense to buy the best one you can.
The uncomfortable truth is that not all oil filters are created equal, and you have to hunt for quality. The modern automobile is put under a lot of stress. So you need to take every measure to keep it in the best condition possible.
The Best Oil Filters
Let’s take a look at some of the better options available:
1. Mobil 1 Oil Filter

What to Look for in an Oil Filter
Motor oil is used to lubricate engine parts and in the case of oil filters, it absorbs and holds organic and inorganic contaminants. Organic contaminants consist of bugs and bacteria. Inorganic contaminants consist of metallic particles.
The oil filter plays one of the most important roles in car maintenance. As we mentioned it filters organic and inorganic particulates from entering your engine. The filter is essentially the kidney of the vehicle.
Let’s take a look at the different types of oil filters.
Types of Oil Filters
There are a few different types of filters. They vary based on their anatomy and method of filtering particulates. Let’s take a look at some of the different types available.
Mechanical filters are the most common type of oil filter. This filter makes use of materials like pleated filter paper or cotton waste to suspend the particulates. As you might imagine though, as more and more particles are suspended, the flow of oil slows down. As a result, mechanical filters need to be changed more frequently.
The first oil filters to come out were the cartridge. These cartridges are a permanent housing where you need to replace the filter media. The design has improved and they now spin-on which means they are quite easy to change.
As the name implies this filter uses magnets or electromagnets to suspend metal contaminants from the oil. Cleaning this type of filter only requires you to remove the collected metallic impurities and you won’t need to replace the filter. However, they are ineffective on dust.
These filters are also known as gravity bed. They use the natural gravitational forces to settle suspended materials. However, they aren’t the most efficient at filtering contaminants.
Centrifugal or “Spinner”
Similar to sedimentation, it uses natural centrifugal forces, ie forces as a result of rotation. These filters are comprised of two sections, a housing and membrane. When the media is clogged you only need to replace it while the housing chamber is usable. An important component of spinner filters is the base gasket. You should have a mechanic inspect the base gasket every 3,000 miles.
Oil Filter Media Type
This is the part of the filter that does the cleaning. It looks like paper, but it can be actually made of cellulose, synthetic or a mix of both.
This media can be made of nylon, polyester, or glass. They are more efficient because the fibers are smaller. These fibers are crosshatched which allow for the finest particles to be filtered while still maintaining flow rates. Synthetic media can remove particles ranging from 20-40 microns. These should be replaced every 5,000 to 7,000 miles. The only downside is they are more expensive.
Most disposable media contain cellulose. It’s a plant-based material that’s inferior to synthetic media. This filter can help with particles 8-10 microns in size. These filters should be checked or replaced every 3,000 miles. It performs better with heavy oils and keeps its form under high pressure.
This media is the most expensive. It is made of final metal or microglass. The mesh consists of fibers that are ten times finer than cellulose. They also have less restriction on the flow of motor oil. These filters need to be checked or replaced every 10,000 miles.
Oil filters are an essential component of your vehicle. They help keep your oil flowing properly and prevent any major engine failure. Overall you can’t go wrong with any of the options listed. We’ve found synthetic media to be the best in terms of performance and you should look for filters that are rated for 5,000 to 10,000 miles.
