Without oil, your motorbike air filter won’t trap the sand and other foreign particles, which could damage your motorbike engine permanently. 

What Happens if There’s No Oil in the Air Filter? 

So far, you understand that motorbike oil is the prime requirement for your motorbike air filters. Now the question arises, what happens if there’s no oil in the air filter? 

Suppose there’s no oil in your motorbike air filters. In that case, your motorbike air filter won’t work correctly because the oil is responsible for trapping its foreign particles. Also, foreign particles will enter the engine, combined with motorcycle oil, and increase the oil viscosity. 

And once the oil becomes viscous, your motorbike engine will starve for the proper circulation of motorbike oil, raising the friction between the piston and the walls. 

In simpler words, the oil in your motorbike air filters protects your motorbike engine from various damages.

Do Every Motorbike Air Filters Need Oil? 

So far, you understand that oil is essential for motorbike oil air filters to keep the engine in good condition. Now the question arises, Does every motorbike air filter need oil?

If you’re using oil-based air filters, you should change the oil in the filters every 13,000 miles. However, if you’re using a dirt bike and do a lot of off-riding, it would be best to change the oil every 7,000 miles. As off-riding causes sand or foreign particles to enter the motorbike engine. 

Dirt bikes also require a lot of air to generate enough power to do off-riding, and that’s why experts recommend inspecting the motorcycle air filters every two months. 

Are the Oil Air Filters Good? 

So far, you understand that motorbike air filters need regular inspection. Still, now the question arises are the oil air filters good? 

Oil air filters are considered the best in the industry because it traps almost all foreign particles from entering your motorbike engine. Oil air filters have better efficiency than any other air filters out there. However, it may require a lot of maintenance, like regularly changing the oil in them and inspecting them every two weeks. 

In simpler words, you can only go with the oiled air filter when you’re ready for messy work and maintenance. 

Additionally, if you own a dirt bike, you should use oiled air filters because of their efficiency. The dirt bike needs a lot of clean air-fuel mixture to work fine, so you should go with the oiled air filters. 

However, suppose you’re an average city rider. In that case, you can go with ordinary OEM air filters as they don’t require much maintenance and carefulness. 

How Does the Motorcycle Air Filter Work?

The motorbike air filter is undoubtedly the most crucial part which you need to clean or replace frequently. 

The air filter fitted in your motorbike comes with unwanted particle-catching properties. Manufacturers made them from a material that can catch unwanted particles easily. 

Types of Filter: How Does Different Air Filter Work:
OEM filters.It comes with tiny pores and viscous liquid for blocking all unwanted particles. 
K&N motorbike air filters.It comes with tiny pores and oiled cotton gauze for blocking all unwanted particles. 
Oiled foam motorbike air filters. This filter comes with thick oil and numerous pores to wiggle the air. 
Table Explaining Some Types of Air Filters Along with Differences Between them.

Filters like OEM filters come with tiny pores; even modern OEM filters come with viscous liquid in these pores. 

The tiny pores and viscous liquid between them cause the air to pass through them quickly but not dust. 

While filters like K&N motorbike air filters come with oiled cotton gauze and more porous material.

The more porous and oiled cotton gauze causes the air to flow through them quickly (more easily than OEM filters) but blocks almost all dust passing through them. 

Last but not least, the oiled foam motorbike filter works the same as the K&N filter, but the only difference is that oil in oiled foam is much thicker than the K&N filter. 

The foam material in oiled foam motorcycle filters causes the wind to wiggle, thus providing the maximum dust-capturing properties. 

And no doubt why riders call this filter a “deep filter.”.
