Well, keep in mind that this jug probably sat for weeks without really moving (it was priced cheaper per qt than a single qt or a case of 6 qts). The oil in my engine doesn't sit for that long. Also, it wasn't like a 1/4" of sludge or anything; just a little brown "stain" at the bottom of the jug. Nothing that concerned me really.
