I should have a bottle or two left from the BOGO offer... I will check this morning.
Jokes aside, I feel the issue is serious. I'm surprised Johnny really didn't chime in which a more meaningful post, although he is not obligated to .... uhmm?

I found this item on the Lube-Tips website. It is referring to industrial lubricants, but the same is probably true for motor oils.
============================================

Q & A: Stored Oil vs. In-service Oil Life

"I heard that oil has a shelf life of one to two years, but oil in service can last for several years. How is this?"

What you have alluded to is true. Oils do have a fairly short shelf life compared to the length of time they can last in service, if properly maintained.

The issue here is additive solvency as it is commonly referred to. Chemically speaking, "additive solvency" is a bit of a misnomer, as many additives are mixed or suspended, rather than dissolved in the base oil. When the lubricant is stored for an extended time, the additives can settle out. This is particularly true of lubricants that have high additive treat rates, and leaving such oils sitting for extended periods can leave a thick sludge at the bottom of a drum. The problem is exacerbated by base stocks with a high nonpolar content, given that many additives are polar in nature.

Using the oil effectively keeps the additives well mixed. If you can limit particulate and moisture contamination to the minimum you will avoid particle scrubbing, water washing and other destructive depletion reactions. As a result, your oil will likely last for a substantially longer time than its shelf life.




In the 80's I saw this REALLY well with M1 15w-50. If it was cold out (it was used as make up quart kept in the vehicle) you would pour out basestock (very thin) and then get a very heavy (at colder temps) motor honey in the bottom of the bottle. I'm sure that they worked out some of those problems now ..but it would still come down to either a blending error ...or too little carrier ..or too much additive (both would appear the same). One would be tolerable with excess additives falling out ..the other would mean less additives in suspension.

..or so I reason

called PENNZOIL tech on this issue , said there is extra addative pack in the PLATINUM , which causes the fallout and not to be concerned . Also , stated you can shake bottle violently and wouldn't help to mix to consistency . Perhaps a paint shaker might work , if yeh have one onhand or go to nearest home improvement or paint center .

I wonder how many micron particles are those at the bottom of the bottle? I wouldn't want to use bypass filtration or else I would lose the extra additive pack

I'm surprised that you do not store your quarts in a bottle rotation machine. It's like the boxes that store your Rolex in that move back and forth to keep the self winder cranked up. You just set your oil storage device to turn the bottles over three times a day. They hold 12 bottles and the average BITOG member would need 4 or 5 machines. Just remember that if you're storing inferior oil you must set the timing to 6 times a day. Just make sure that at midnight the bottles are all right side up, that's midnight GMT. Also the labels must be facing forward and you should be careful not to mix different brands of oil on the same device, and never mix conventional oil with synthetic. You can also order these devices with heaters if you live in an are where there is cold weather.
 
What? You guys don't have the "rocking mixer"? No wonder. I thought all of you had one of these with your next oil change sitting "on deck" in a pre-OCI staging routine.

Get with the program, guys

Well several things:
1. I did not nor do not think it is serious.
2. With all the emails and phone calls to the tech folks, they are the one's that should answer these technical questions.
3. If I would have given an answer, it would have been the same responce the phone tech gave.
4. I don't have a clue what Shell is doing anymore.
5. Proof is in the UOA's
 
Shaking the product is probably not going to effectively return the adds to suspension. The fluid will more than likely need heat to do that. And the needed heat is probably available in the sump.

OK...looks like someone didn't get it...that OK..i'm sure someone will re read the post, look at my screen name, and fill you in

Everyone says that they've 'seen this in valvoline' and other oil, but i've never seen a picture. if this were common, and all you guys have seen it, i'm sure i would of seen pictures elsewher.
Also, even the AMSoil guys were worried about it.
..Just food for thouht.

That stuff is like API SG. Anyway, my PZ bottles from yesterday drained clear, dated 2007.




Not with "PureBase" on the label. It's SJ, maybe even early SL.

I re-read your post, and looked at your screen name, and still I can't figure out what Pennzoil had to do with you having to get rid of your Expedition.

Perhaps you are famous, and there is a story behind your fame that someone will fill us in on....?

I've been staring at his screen name for ten minutes now. I still don't get it. Perhaps he's a big Kiefer Sutherland fan and Kiefer Sutherland is on an anti-Pennzoil campaign?
 
I don't get it. What does Jack Bauer and "24" have to do with Pennzoil?
