After cleaning or replacing the paper filter or foam filter, it’s crucial to check for any further problems. For example, ensure that no oil leaks or other issues could have caused the air filter to become soaked in oil.

If you notice any other problems, e.g., a stuck pull cord, address them immediately to avoid further damage to your lawn mower.

Tips for Effectively Dealing With This Issue

  • Always wear gloves when cleaning or handling the air filter to avoid getting oil on your skin.
  • Use a soft brush to scrub away any stubborn stains on the filter gently.
  • Regularly check and clean your lawn mower’s air filter to prevent it from becoming soaked in oil in the future.
  • Consider using high-quality oil and changing it regularly to prevent buildup in the air filter.
  • If warm or lukewarm water and dish soap is ineffective in removing the oil from the air filter, consider using a degreaser specifically designed for cleaning air filters. Follow the manufacturer’s instructions and rinse the filter thoroughly after cleaning.
  • A clogged or malfunctioning carburetor can cause a leak into the air filter. Inspect the carburetor for any blockages or damage if you notice excessive buildup in the air filter.
  • Consider installing a catch can to prevent excess oil from entering the air filter. The catch can trap oil and prevents it from entering the engine and air filter.

Why Does an Air Filter Get Soaked in Oil?

Just like a bad lawn mower battery, a soaked air filter is a common problem that can occur in lawn mowers. There are several reasons why this issue can occur, including:

Overfilling the Oil Reservoir

Overfilling the oil reservoir can cause any excess to be drawn into the air filter. This can result in the air filter becoming saturated.

Clogged Breather Tube

The breather tube allows air to flow through the engine, preventing debris and oil from entering the air filter. However, oil can be forced into the air filter if the breather tube becomes clogged with debris.

Worn Piston Rings

If the piston rings in the engine are worn or damaged, oil can leak into the combustion chamber and be burned off, causing the air filter to become saturated with oil.

Poor Quality Oil

Using low-quality oil or oil that has not been changed regularly can cause oil to build up in the air filter. You really need to use the right oil for your mower.

Tilted or Improperly Stored Lawn Mower

Oil can leak into the air filter if a lawn mower is stored or operated in a tilted position. Understanding the causes of a lawn mower air filter soaked in oil is essential in preventing this issue from occurring in the future.

By addressing the underlying cause of the problem, you can ensure that your lawn mower runs smoothly and efficiently. The following section will discuss prevention tips to avoid air filter soaking.

How to Avoid an Oil-Soaked Air Filter

Preventing an air filter from becoming soaked in oil is essential to maintain the optimal functioning of your lawn mower. Here are some prevention tips:

Check and Change the Oil Regularly

One of the most critical steps in preventing an air filter from becoming soaked is to check and change the oil in your lawn mower regularly. This is because overfilling the oil reservoir or using old, dirty oil can cause excess oil to be drawn into the air filter, resulting in it becoming saturated with oil.

To check the oil level, locate the dipstick on your lawn mower, usually located near the engine. Make sure the lawn mower is on a flat surface, and remove the dipstick to check the level. If the oil level is low, add the recommended amount specified in the lawn mower’s manual.

Changing the oil at the recommended intervals specified in the manual is also essential. This will help prevent an oil-soaked air filter and extend the life of your lawn mower engine. But, again, be sure to use the recommended type of oil and follow the manufacturer’s instructions.

Regularly checking and changing the oil in your lawn mower can prevent an oil-soaked air filter, allowing it to function correctly and efficiently.

Checking oil on a lawn mower

Use High-Quality Oil

High-quality oil that meets the manufacturer’s specifications is essential to prevent buildup in lawn mower air filters.

Low-quality or cheap oils may not provide adequate protection for the engine and can cause excess oil to be drawn into the foam air filter or paper air filter, resulting in it becoming soaked in engine oil.

Check the manufacturer’s recommendations in the owner’s manual to ensure you use the correct type of oil for your lawn mower. They will typically specify the type of oil suitable for your lawn mower engine and the recommended oil change intervals.

It’s important to note that different types of engines may require different types of oil. For example, a two-stroke engine may require a specific type of two-stroke oil, while a four-stroke engine may require a different type of oil.

Using the wrong type can cause significant damage to the engine, including increased consumption and potential engine failure.

Using high-quality oil that meets the manufacturer’s specifications can prevent buildup in the air filter and ensure that your lawn mower runs smoothly and efficiently.

Check and Clean the Lawn Mower’s Air Filter Regularly

Checking and cleaning the air filter at regular intervals is essential to prevent buildup in the air filter. A dirty or clogged air filter can restrict airflow into the engine, causing the engine to work harder and potentially drawing excess oil into the air filter.

To check the air filter, locate the air filter housing on your lawn mower. It is usually located on the side or top of the engine and is covered by a plastic or metal housing. Remove the housing and take out the air filter. Check the filter for dirt, debris, and damage.

If it is dirty, clean it by gently tapping it against a hard surface or blowing compressed air through it. If it is damaged or excessively dirty, replace it with a new one.

It’s essential to follow the manufacturer’s recommendations for air filter maintenance, including the recommended cleaning or replacement intervals. Neglecting the air filter can reduce engine performance, increase fuel consumption, and potentially cause costly engine damage.

By regularly checking and cleaning the air filter, you can prevent buildup in the air filter and ensure that your lawn mower runs smoothly and efficiently.

Following these prevention tips can reduce the likelihood of an air filter becoming soaked. Regular lawn mower maintenance can also ensure that it runs smoothly and efficiently, avoiding any costly repairs in the future.

Conclusion

Dealing with an oil-soaked lawn mower air filter can be frustrating and time-consuming, but it’s essential to address it promptly to prevent further damage to your lawn mower’s engine.

By following the tips outlined in this article, such as checking and changing the oil regularly, using high-quality oil, and checking and cleaning the air filter regularly, you can prevent oil buildup in the air filter and ensure that your lawn mower runs smoothly and efficiently.

It’s always a good idea to consult the owner’s manual for specific instructions and recommendations for maintaining your lawn mower. With proper maintenance and care, your lawn mower can provide reliable performance and help keep your lawn looking its best.
