I just purchased a 445. Have used it a couple hours. So far, I have not noticec any oi leaking on mine.
I purchased a Polan Pro 20" from Lowes. I had difficulty starting it, compared to my two Husky's I own. Seems to be temperamental. Is nowhere near my Husky 340. I really find it difficult to believe it was a Husqvarna-owner product.
