How long does an oil filter last?

To maintain engine oil’s health and engine performance, it is important to change the oil filters on a regular basis. You may have used a poor oil filter or an inferior oil to ensure your engine oil lasts.

Under normal driving conditions using a conventional oil, Wix oil filters can last between 3,000 and 5,000 miles. They may last as long as 3,750 to 10,000 miles under severe driving conditions.

On the other hand, K&N oil filters last up to 10,000 miles.

Compatibility with Vehicles

Each oil filter is not suitable for all vehicles. Different oil filters have different designs and will yield the best results if they are used in accordance with the vehicle they are intended for.

Wix oil filters have been designed for trucks, buses, cars and other vehicles. Whereas K&N oil filters were initially designed for racing and off-road vehicles. 

The company has developed oil filters that are compatible with cars, trucks and racing cars, as well as motorbikes, motorbikes, watercraft, and off-road vehicles.

Compatibility with oil

The oil filter must be compatible with the oil type used in your vehicle. There are many oil filters on the market today, some only compatible with a particular type of oil.

Wix oil filters work with both conventional and synthetic oil. On the other hand, K&N oil filters are also suitable for both oils but work best with denser oils.

Filter Media

The filter medium is crucial in removing dirt particles from oil. Wix oil filters utilize glass-enhanced filter media which is more efficient than synthetic and cellulose media.

K&N oil filters use synthetic-based filter media inside most of the oil filters. Synthetic-based media is more porous and less efficient than glass-enhanced media.

Anti Drain Back Valve

In the case of the difference based on the anti-drain-back valve, both Wix and K&N oil filters stay at the same level. Both oil filters from these companies feature silicon-type antidrain back valves.


Prices for different models vary based on their performance. Wix oil filters are a bit costly as compared to K&N oil filters. Most customers have found K&N filters to be available at affordable prices.

Bottom line

Wix was founded in 1939. The company produced its first oil filters between 1949 and 1954. It has grown to be a top-selling brand of oil filters. On the other hand, K&N started its journey of manufacturing oil filters in 1969 and has been rolling exclusive quality oil filters since then.

It is always recommended that you purchase the oil filter as per your vehicle’s owner manual.
