The "shelf life" of oil is basically because about every 5 years a new API standard emerges and makes the oil "obsolete". If you have that 5 year old oil on the shelf, yes, it should be shaken before use because the additives WILL settle to some extent.
Also, While most know of ZDDP, there are other minerals in motor oils that replace ZDDP, such as Boron, etc. Where the cams go flat is more the way they are lubed. ZDDP provides a plating barrier between the parts, whereas newer oils do not provide that. If you took a flat tappet cammed engine, started it and continuously ran the engine until failure, the cam would show normal wear. Its the stopping, and oil dripping off the parts, that cause that dry startup issue that ZDDP took care of.

So when does the aging process start? Answer: There is no way to tell how old oil is without a manufacturing date stamped on each container.
It is nothing more than a guesstimate at best IMHO

My point is how long did the oil sit at the refinery until shipped to store, (a year or more), then how long did the same oil sit in the back room at Pep-Boys (two years) before making it onto the shelves?

Let say your right, after all this came from a Mobil website correct?
This generates more questions than answers.
If there is a shelf life for synthetic Mobil 1 oil, then you would think it would be stated somewhere on the label or stamped on the bottle, correct? To have an expiration date, each quart of oil should have a manufacturing date stamped somewhere to correlate the expiration date correct?
I can’t find anything on the label supporting your statement, you would think that would be very important information.
I’m not doubting your statement, you’re just the messenger. I’m questing its validity. Did this person have a name or title to follow up on?

And yes each bottle of oil should and does have a manufacturing code stamped on the bottle. I just checked two of my Mobil-1 15W-50 5-quart jugs and they both have a date code stamped on the jug. You have to look closely to see it. Mobil 1 prints the codes using laser dots instead of ink, cut into the product container. The two jugs I looked at have the following code
11016G29A ---> 29-July-2016
11014H19A ---> 19-August-2014

I'm finished, not going to reiterate any more after this post: I have 15 quarts of Mobil 1 20w 50 V-Twin synthetic oil on my shelf. No laser, stamp code, crayon, hieroglyphics or date anywhere on any of the 15 quarts inspected by 4 people that have sworn not to be intoxicated and claim they have corrective updated glasses resulting in 20/20 vision. All claim unanimously at the same in broad daylight at this time of inspection on every one of the above stated 15 containers of oil.
It’s time to move on.

Mobil 1 Racing 4T 10W-40 @ $10.99 per quart
Mobil 1 V-Twin 20W-50 @ $10.99 per quart
I checked a number of the above mentioned products on the shelf, and they all had a manufacturer date code on them. Some of the codes were a bit difficult to read.
Mobil 1 Racing 4T 10W-40, manufacture code: 10116D30A (April 30, 2016)
Mobil 1 V-Twin 20W-50, manufacture code: 10116F04A (June 4, 2016)
I've attached a picture to show where to look for the Mobil 1 manufacture code. You need to tilt the bottle and look closely under a fairly bright light.
Maybe the above person and his buddies are inebriated.
