I stopped using FP3000 in my car for a few weeks as an experiment and had about 10oz. sitting in my LCD container in my basement (where all the rest of my oil is, since it's temperature controlled) and then when I continued using it again, I noticed that in the bottom of the bottle there were a bunch of little flakes of additives or something else that appeared to have settled out of suspension. It almost looked like a bacteria sample on the bottom of the container. Anyone else experience this or have any insight to offer to this? I'm afraid to put it into my car now..
