Oil on air filter

[ebo 4356]

I just cleaned my air filter today and found some black spots on the inside of the filter and i assume its not a good thing to have on your filter.

I really would not worry about it. If you see alot of oil then panic.

your filter will get stained over time. i would just clean it good and see. it may be time to replace it too. just make sure you use oil made for a foam filter (i am assuming you have a foam filter).

As long as its not excessive don't worry about it. However if it does you have some serious issues and should have a mechanic look at it.
