Same problem hear, I ignored the posts of 455 oil leak problems, purchased anyway< dummy me> now I have oil even after cleaning all over garage! I purchased it to replace my 20 inch homelite from the 70,s that leaked oil everywhere, some automatic oiler, lubes garage floor well! I am going to pursue with a dealer or return it !
+I am surprised by this review. I agree with the dealer, You have to make sure for proper lubrication of the engine cleanliness of the bar and proper chain lubrication. If you watched the videos, which are long but most useful! Do not force saw and do not let rpm down, or chain will catch. Used properly, these are the best chainsaws there is.
