My '03 had a burr on one of the friction plate fingers that was causing the clutch to drag. I suppose if the burr was such that it could hold the stack apart somewhat overall contact area would be reduced and it could slip, but its just a guess. When you put the new plates in, did you soak them in oil overnight? My '03 occasionally groaned in the worst of conditions, but only for a second or two. The 300 has a bit more motor, so maybe a little more clutch spring preload won't hurt, as long as the pull is still nice. Try the washers, its easy. Either Rotella is fine, the 5W-40W synthetic will probably drag less though.
