And does ability to hold solids in suspension over longer downtimes really not mean anything? It was an uncracked bottle of the new design, no reason for me to believe it had been sitting more than maybe a month or two. I am also under the impression that the pickup tube in an engine feeds from the bottom of the pan first. So maybe the worst that can happen is the filter has to do its job better, again, im just curious if anyone has seen this elsewhere, or if i should worry this batch may have had an issue? I care about the cars i service and the people i service them for. If i should be trying to upsell a better product for their benefit, i would like to know! Especially considering Fords now have one of those 10k oil clocks and many of our customers follow it. I think thats pushing it on ANY dino, but the old [censored] whos been their the longest thinks the only fix is shorter ocis. I decided to come here to learn, and maybe prove him wrong!

Your not the first to report additives falling out of suspension in Pennzoil. Do a quick google search. Pennzoil even commented on it in the FAQ section.
Good hunting!
