 Oil Filter Reviews


Mobil 1 M1 Extended Performance 

If you've read our selection of the best synthetic motor oils, you'll have seen that we don't list any Mobil 1. There are better. However, when it comes to oil filters, Mobil 1 stands out from the crowd and is, no doubts, the best oil filter you can get your hands on.

Let's have a look at its features.


Mobil 1 Extended Performance filters are well built in-and-out.

The shell withstands nine times the normal system operating pressure, up to 615 pascals per square inch, which is crazy.

It incorporates a silicone anti-drain back valve to prevent dry starts by eliminating internal leakage.

The inner filter​ holds double the contaminants compared with the competition, with a total of 28.0 grams.

The filter is highly efficient, rating 99.6 Multi-Pass Efficiency, thanks the advanced synthetic fiber blend media.

This is a filter that will perform at the highest standards in the industry, ensuring proper lubrication of the engine.​




Royal Purple Extended Life Oil Filters

Royal Purple concentrates efforts on producing high-performance oil filters and motor oil. Their Extended Life series is absolutely superb, with the only downside of being more expensive than the Mobil 1. Some people believe is justified. Let's jump into the review.


The Royal Purple incorporates micro-glass media that is 100% synthetic and removes particles at a 99% filtration efficiency. We see that is very very close to the numbers of the Mobil 1. It also incorporates anti drain-back valve to prevent dry starts.

The rubber base gasket is heavy duty made and ensures a leak-free sealing. The housing (outer shell) is ultra strong, made to endure the highest inner presures. This is a filter specially recommended for turbocharged engines

Bosch Premium FILTECH Oil Filter

Bosch is the world’s largest supplier of automotive components. One will hardly ever go wrong with Bosch (Well, you do can, I hate Bosch Spark Plugs). The FILTECH is their premium line of oil filters and it is high-performance oriented.


This German made filter comes with exclusive FILTECH media technology that filters out more harmful contaminants for greater engine protection. As the other top filters reviewed, it also contains a silicole anti-drain back valve to prevent dry starts. That is a standard in high performance oil filters.

K&N Pro Series

K&N Pro Series Oil Filters have been specially designed to improve engine performance by reducing oil filter restriction. The Pro Series oil filters provide outstanding filtration and engine protection throughout their service life. Let’s see some features


High flow filter designed to improve performance. This sacrifices the incredible %filtration numbers we've seen in the top 3 filters to get better oilflow. For turbocharged, big engines this may be the smart way to go. 

The total capacity is 14 grams which is above average but nothing as high as what Mobil 1 or Royal Purple offer.​

Motorcraft Silicone Valve Oil Filters are designed and tested to meet OE specifications for durability and reliability under extreme conditions. They are built to maximize performance and are made from high-quality materials. They offer high resistance which ensures lasting durability.


Motorcraft is the OEM for Ford, Lincoln and Mercury. It comes with a pressure reflief valve that prevent cuts in the oil flow when the filter gets clogged, or under extreme cold conditions when the oil viscosity is too high.

Motorcraft FL Oil Filter Review

The capacity is around 12 grams which is still good figures although not as impressive as we have seen further above on the table.

The outer shell is extremely hard and is meant to withstand heavy duty.




AC Delco Professional

For GMC, Cadillac, Buick and Chevrolet engines this is the oil filter you are looking for. We couldn't finish this segment without adding the best oil filter for trucks to the list. 


Being the OEM for Chevrolet, GMC, Buick and Cadillac simply gives you the guaranty that you get a great filter. 

This is usually a really expensive oil filter since it incorporates a WIF (water in fuel) plug and it is rather big.

The model in the picture is the TP3018 which is a Duramax filter and replaces the older versions.

Oil Filter Buyer's Guide

In the following guide we are going to cover the essential factors to consider when we pick an oil filter for our car, basic recommendations for proper maintenance and extra information on how filters are done, what do they have inside and why some filters are fantastic and some others are a waste of money.

We hope that this guide will answer all your questions and doubts regarding oil filters and if it doesn’t please send me an email at alexmeyer@gear4wheels.com and let me know what's missing.

1. What is an oil filter.

A filter is in general terms a device meant to accumulate foreign bodies such as dirt, water or metal particles and prevent them from flowing freely throughout a circuit, potentially causing severe damage to other components such compressors, pipelines or injectors to name a few.

In a car, the oil filter plays an essential role.

Motor oil lubricates the engine, which ensures all moving parts to work nice and smoothly, cooling them down and keeping them lubricated to minimize friction (which ultimately produces metal wear, loss of performance and mechanical failure).

In order to keep the oil clean from harmful agents such as atmospheric dirt, combustion by-products (such as soot, acid, water) and metal particles an oil filter is needed.

2. How are oil filters made and how do they work.

This video covers this in a great way. It's only a couple minutes long so check it out!

For those who are less interested in the specifics of oil filters and more in the actual how-to-buy-the-best-filter, let’s move forward.

3. How to pick the right oil filter for your car.

So at the beginning of this page we’ve reviewed the best oil filters available in the market, sorted by manufacturer.

This however is not enough information.

I’ve you’ve read each filter review you probably have seen that we link to the manufacturer search tool to see what fits your car.

This is essential.

There are few things more frustrating than having your car up in the jack all bled out, oil filter in hand ready to screw it in just to discover that the new filter simply doesn’t fit.

It is a situation that we’ve faced dozens of times and we want to save you the headache.

This is our Step By Step supereasy guide to buy the right filter.

Step1: Click to check compatibility at Autozone’s website
oil filter compatibility

Input your Make, Model, Year and Engine and click at add vehicle. Autozone’s search engine will then display something like this.

oil filter and accesories

Then Click at “Oil Filter” and you will see something like this next image

oil filter selection

Those are the filters that fit your car. The circled “Part Number” is the information we are going to use in step 2.

Step 2. Select the BEST brand.

Go back to the top and check our reviews.

Pick your favorite brand from the ones that fit. (we have sorted being #1 the best). In our example, for the Honda Civic we would select Bosch filters.

Step 3. Buy the Best Oil Filter.

Click at your brand of choice and it will bring you its Amazon’s catalog.

With the Part Number from Step 1 (in our example part nº 3323), select the right filter.

bosch oil filters

Then simply proceed to buy it from Amazon as you would do with any other item.

For a double check, you can always add your car’s data at Amazon’s “My Garage” and amazon will tell you if it fits.


Sometimes amazon will say “it does not fit” and it does indeed.

But as a double check is a good thing to do. Simply input your car’s data (year, make, model, engine, version).

4. How often should you change your oil filter.

Everytime you change your car’s oil, you should change the filter.

Whilst most oil filters will withstand longer miles than conventional oils, new oil would get contaminated by the nasty stuff retained inside an old filter if you don’t change it.

If your car is running conventional oil 3000 miles is the recommended.

However, if you run with synthetic or full synthetic oil, that isn’t the case.

We’ve covered in another post what’s the correct synthetic oil change interval, so check it out.

6. Final thoughts

Factors such as the quality of the filter media, the total capacity of the filter, the by-pass pressure, structural integrity and the particle capture efficiency are to consider to pick the best oil filter.

That being said, Gear4wheels recommends Royal Purple, Mobil 1 and Bosch.
