Is a Dry Or Oiled Air Filter Better?

If you’ve ever wondered whether a dry or oiled air filter is better for your car, you’re not alone. There are pros and cons to both types of filters, and the best choice for you will depend on your driving habits and preferences. Here’s a closer look at the benefits of each type of filter to help you make the best decision for your car.

Dry air filters are less expensive than oiled filters and require less maintenance. They can be used for up to 30,000 miles before they need to be replaced, making them a good choice for people who don’t want to have to regularly replace their filters. Dry air filters also don’t need to be oiled, so there’s no risk of over-oiling and damaging your engine.

Oiled air filters capture more dust and debris than dry filters, making them a good choice for people who do a lot of off-roading or drive in dusty conditions. Oiled filters also last longer than dry filters – up to 50,000 miles – so they may be a better choice for people who want fewer filter changes over time. However, because they need to be regularly oiled, they can be messy and difficult to maintain.

When it comes to your car’s air filter, you have two choices: dry or oiled. But which is better? Dry air filters are made of paper or cloth and can be treated with a special coating to help trap more dust and dirt.

Oiled air filters are usually made of cotton gauze that has been soaked in oil. The oil helps to catch and hold onto tiny particles of dirt and dust. So, which is better?

It really depends on your needs. If you live in a dusty area or do a lot of off-roading, an oiled filter may be best for you. Oiled filters can also last longer than dry filters (up to twice as long, in fact).

On the other hand, if you don’t want to deal with the hassle of cleaning and re-oiling your filter, a dry filter may be the way to go. Whichever type of filter you choose, make sure to change it regularly according to your car’s recommended maintenance schedule.

Oiled vs Dry Air Filters – Which Is For You? Ep. 3

Oiled Or Dry Air Filter for Diesel

When it comes to choosing an air filter for your diesel engine, you have two main options: oiled or dry. Both have their pros and cons, so it’s important to choose the one that’s right for your needs. Oiled filters are great at trapping small particles and dust, making them ideal for dusty environments.

They need to be cleaned regularly, however, as the oil can eventually clog up the pores of the filter. Dry filters don’t require any maintenance other than occasional replacement. They’re not as good at trapping small particles as oiled filters, but they can handle larger debris and are less likely to clog up.

Does Oiled Air Filter Damage Engine?

Oiled air filters can cause damage to engines in a number of ways. The oil can seep into the engine, causing bearings and other moving parts to fail. It can also cause sludge and deposits to build up on engine components, leading to reduced efficiency and increased wear.

In extreme cases, oiled air filters can cause engines to seize up entirely. For this reason, it’s important to change air filters regularly and avoid over-oiling them.

Should an Air Filter Be Oiled?

While there are many air filters on the market, most of them do not need to be oiled in order to work properly. The only time you may need to oil an air filter is if it is a reusable one that you can clean and reuse. If your air filter is not reusable, then there is no need to oil it.

Can You Oil a Dry Filter?

Yes, you can oil a dry filter. This will help to make the filter work more efficiently and last longer. Make sure to use a light oil, such as olive oil or vegetable oil.

Apply the oil to the outside of the filter and then rub it in with your fingers.

How Do You Tell the Difference between Oiled And Dry Air Filters?

If you’re not sure whether your air filter is oiled or dry, there are a few things you can look for. First, check the manufacturer’s instructions. If it’s an oiled filter, it will likely need to be lubricated regularly with engine oil.

You can also tell by the appearance of the filter – if it’s dark and dirty, it probably needs to be replaced. If it’s clean and light-colored, it’s probably still good. To test whether your air filter is truly clean, hold it up to a strong light source.

If you can see through easily, then congrats – your air filter is clean! However, if you see any dirt or debris buildup on the surface of the filter, then it needs to be replaced immediately.


There are pros and cons to both dry and oiled air filters. Oiled filters tend to last longer and can capture smaller particles, while dry filters don’t require any maintenance and are less likely to cause engine issues. Ultimately, the best choice depends on your driving habits and preferences.
