How does oil get into the air filter?
The PCV valve is similar to an engine oil filter in that it eventually becomes clogged with excessive debris (in this case — engine oil) and should be replaced as recommended by your vehicle’s manufacturer. If the PCV valve is not replaced as recommended, excessive oil will blow through the PCV valve and enter the air intake system.
Why do I need to change my air filter?
The positive crankcase ventilation (PCV) valve was introduced as one of the first emissions controls, and redirects blow-by back into the air intake instead of letting it pollute the environment. A PCV valve needs to be replaced occasionally, just like an oil filter.
What happens when an air filter is clogged?
When the air filter becomes clogged with debris, it can cause the engine’s fuel efficiency and power output to decrease. If oil is found inside the air filter, it can also significantly impact the engine’s performance.
Where is the air filter on an engine?

Why does my lawn mower have oil in the air filter?
Lawn mower oil in an air filter reliably clogged with oil is most likely the result of turning the mower over the off-base way once you work on the blades underneath the cutter deck. In the event that you turn the mower over with the air channel down, the motor oil will spill out and into the channel, clogging it.
