Anyone used this stuff? I couldn't find the ZDDPlus locally but Advance had this. The reason I'm asking is I changed the oil last night in prep for start-up today (hopefully). I put in the Lucas stuff and 4 quarts. I primed the oil system, and when I went to add more oil to top off, i noticed some gritty looking crap on the oil baffle. When you first touch it lo feels like fine sand, but if you rub it between your fingers, it breaks up quite easily and no longer feels rough. Anyone every had this issue before? I'd hate to start this thing and trash all their bearings, and I'm half afraid that hte damage may already be done as I primed the motor before I saw it. Any thoughts? also, which way do you spin the oil priming rod (just to make sure i did it right)...I think I did Bill M 65 Coronet 500 'vert
