You might file this under the "no good deed goes unpunished" line, but I loaned my 441 to my father and his work crew to do some clean up at several cemeteries. When I got it back I cranked it and ran it and noticed that they ran motor oil or some cheap lubricant through the oiler. The chain was blacker, bar too.
I also noticed that when I replaced the inferior oil with Stihl bar and chain it continued to leak from the cam cover. Now, I was standing in my garage running the machine and it was dropping large droplets of black oil on the concrete. Is that normal, or is it not? I have never seen it do this before, but I have never really run the thing for several minutes in the garage for fun. Always out in the field or at the cut site. I would figure fresh bar and chain oil would be fairly clear.
My Stihl man said that the oilers on the 441 are very tough and any damage done by the cheap oil was on the bar and chain. I figure him to know his stuff, but it greatly surprised me see the big droplets of oil coming from under the cam cover. (I do know that the oiler lubes the chain there.)
Thanks for reading and any comments.
