I knocked three good sized holes in the back of my hand when the engine oil filter wrench slipped three times. I wound up driving a long spike through it and got it loosened with that. It seems that they paint the original filter onto the engine. The dealer mechanic tells me the subsequent filters don't stick, but noted that the first one usually does. After I got the filter changed, I ground the corners round on the muffler mount and rounded their edges too.
I have a long handled strap wrench that worked great on the hydraulic filter.
The greasing comes up every 50 hours. The book says to give it, "the proper amount." I asked at the dealer and didn't get that narrowed down much. I guess if there is trouble, I used too much or not enough.
I'm well past my third 50 already.
