Why is there oil in my air filter on my Polaris Ranger?
Cause is normally higher crankcase pressure forcing excessive oil film out the vent hose into the air box due to worn rings. Not a engine killer per say, just not a perfect scenario. You could do a compression check and still have fairly good compression (or not) but still have some wear on the oil rings.
What can I use to oil an air filter?
Use regular motor oil or gear oil. Either will work fine. The most common error, other than letting an ‘old wife’ tell you what to use, is using too much oil. Squeeze it out really well or you will restrict the air flow.
How does oil get out of the air box?
Then it will migrate through the breather hose on the air box. Once there, the only way it can get out is through the drain tube on the bottom. This is what is supposed to happen with motor oil. It is why you have the breather hose to the airbox and the drain tube in the first place.
Why is there oil in the breather tube of a motorcycle?
by Chris Gilliland. A stream of oil, flowing from the engine’s breather tube and into your motorcycle’s air box, is the result of a condition called blow-by. Caused by an increase of pressure within a motorcycle’s engine, this phenomenon forces oil up into the breather tube attached to the crankcase.

I have cleaned the air filter, but it quickly coats wilt oil when the engine runs. Any suggestions on trouble shooting/repair needs.

How does oil end up in air cleaner?
Although system details vary, one solution was to plumb the breather into the air cleaner. The fumes coming from the crankcase are then recirculated back into the engine and burnt. Here’s how the oil ends up in the air cleaner. Crankcases can only contain a given volume of air and its attendant pressure.
