The cutting condition is the key - there is a reason there are 3 options!
Grease or "filter oil" should not be needed.
The yellow mesh ones works perfectly here, and they are easy to keep clean, but I avoid using the black ones.....
I've noticed the same fine dust after the filter as well, hence my interest in the other filter - I jsut picked the felt style up at the dealer at lunch.
So what conditions would the felt one be used in , extremely dusty/ dirty? I wouldn't consider my conditions dusty/ dirty, yet I still have that gunk after the filter....?????
