I ordered mine online and when I got it, it was already pre-oiled. No dripping...however...when I took it off and cleaned/re-oiled myself, it's been dripping ever since. I'm not really sure what I did wrong...I didn't think I put too much oil on...just enough to make the filter completely red, like it was when I got it. It's getting less and less every time...by the time it stops, I'll have to clean it again. Oh well...next time, I'll put even less oil on it.
