Mobil 1 vs K&N Oil Filter

Over time, your engine accumulates wastes and other contaminants that affect its optimum performance. Breakdowns and dry starts happen when large amounts of debris prevent the oil from flowing smoothly to the engine.

A good oil filter keeps this problem at bay; that’s why it has to be replaced regularly. Most manufacturers suggest changing oil filters every 7,500 miles or more, but it also depends on the type of vehicle, driving habits, and external factors such as terrain and temperature.

You may also look up specific oil change intervals on the manufacturer’s manual that goes with your vehicle.

With several oil filters available, I have narrowed down the selection between Mobil 1 and K&N oil filters to help you decide which one is better suited.

Here’s a quick look at the main features of  Mobil 1 vs. K&N oil filter:

Feature K&N Mobil 1
Mileage 10,000 miles 20,000 miles
Longevity Up to 1 year Up to 1 year
Micron rating Between 25-100 microns 30 microns
Compatibility Works well with thick and dense motor oils Can be used with all motor oils
Filtration accuracy 85% 98%

Knowing the Difference Between K&N Oil Filter vs Mobil 1

Champion Laboratories, Inc., the company that makes Mobil 1 oil filters, has been known worldwide for its quality oil filters. On the other hand, K&N Engineering, Inc. which makes K&N oil filters, has been around for decades producing top-notch oil filters for motorcycles, cars, and heavy-duty vehicles.

Both deliver high performance, which explains why they remain two of the most popular oil filters available today. However, there are a few qualities worth knowing when choosing which oil filter is better.

1. Mileage and Longevity


Both K&N and Mobil 1 oil filters go a long way in delivering hassle-free driving. Using state-of-the-art technology, these oil filters dramatically improve your engine’s performance and increase its lifespan.

Mobil 1 is known to work efficiently up to 20,000 miles or roughly a year between oil changes.

K&N high-performance oil filter also has an impressive track record in protecting your engine for up to a year on average, equivalent to 10,000 to 20,000 miles, depending on your vehicle type and/or driving habit.

2. Microns Comparison


Another factor to consider for a seamless driving experience is the oil filter’s ability to keep your engine clean and trap unwanted particles.

Mobil 1’s synthetic blend media is said to filter out particles of 30 microns which is good enough to give you long-lasting protection.

As for K&N, its filtration ability ranges from 25 to 100 microns depending on the variant of your choice – whether K&N select oil filter or K&N gold oil filter.

3. Compatibility


Both Mobil 1 and K&N oil filters are made to work with all types of motor oils. This versatility makes both an easy choice without having to worry about their effect on the engine oil brand you are currently using.

However, K&N, thanks to its higher oil flow, works well with thick and dense motor oils making it best suited for high-performance vehicles such as race cars.

4. Accuracy


Knowing the accuracy level of your oil filter plays a crucial role in keeping your engine clean, achieving long-lasting performance, and providing a money-saving measure in the long run.

Mobil 1’s filtration accuracy level stands at a remarkable 98%, while K&N offers an accurate performance average of 85%.

5. Pros & Cons

Choosing the right oil filter has its ups and downs. While Mobil 1 and K&N oil filters both offer superb performances, there are two sides of the coin that should be looked into.

6. Cost


As a wise buyer, it is likewise important to check the price tag before making that final decision.

Mobil 1 and K&N oil filters are competitively priced, but the cost can vary depending on your chosen vendor, which product you pick, and other external factors.

Mobil 1’s price range starts at $11 on Amazon.

On the other hand, K&N has a slightly higher entry-level price point which can go to as much as $34.95 on Amazon for its premium line.

Which is Better?

With all things considered, it all boils down to this question: Are K&N oil filters good, or is Mobile 1 better?

It all depends on your personal preference. Both brands deliver the goods and work just as well as the other.

You might just want to consider your vehicle type, so you can make the most out of your preferred oil filter. Mobil 1 works compatibly with all types of engine oil, but if you are driving a high-performance vehicle, you may opt for K & N.

Lastly, your budget also plays a pivotal role in deciding which oil filter is ultimately better.


Choosing the right oil filter can greatly affect your vehicle’s overall performance, not to mention the fact that it can give you peace of mind while on the road.

With their immense popularity in the automotive world, the silent battle of Mobil 1 vs K&N oil filters goes on, and the truce lies in your hands.

By carefully weighing in the qualities and features of Mobil 1 and K&N, you are ready to shift gears and choose the right oil filter.
