FYI - Over the past few years I have bought two 850s where the oil drain plugs were in so tightly I could not easily remove them even with a 1/2 rachet that had an 18 inch arm. I was fearful of tearing the aluminum threads out of the pan. In both cases I tried an impact wrench and they were easily removed without damage. It is a mystery why some peoply think over torquing spark plugs and oil drain plugs is a good thing.
