wow...I've never oiled mine either! Something I've never even thought about! Hope somebody that knows posts about it!
I'm hoping this weather misses us again.....every time they have predicted snow for us (NW WI) so far they've only been right once!! It has gone south of us every time! And up til now that upset me as I enjoy winters but now that I got a taste of spring the last few days, I don't want it anymore!!! LOL
