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?

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

How is oil made? First take a thousand years old forest and bury it for a few million years, dig up what is left and turn it into 'oil'. So when does the clock start?!

 

How to read date codes on oil jugs:

 

Interesting, if there were any numbers displayed on Mobil 1 V-Twin oil would consider what you have stated..... As I previously stated there are no numbers stamped anywhere on container.

Appreciate your efforts though!

I guess you could make the same statement about any product that has an expiration date on it put there by the manufacturer. For example your cereal, milk, motorcycle tires, etc. One can sometimes find product in the store that are past their expiration date. You as the consumer can choose to either purchase that product or look for one where the date hasn't expired.
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 guess the manufactures expiration date begins when the oil was manufactured based on the manufacturing date code on the bottle/jug. Expiration date of oil is probably based on a number of items including how the product is typically stored, additives, etc. But I'm just guessing here. A search on the Internet reveals information on this topic.

Yes, there is a manufacturing date code on Mobil 1 oil. Keep looking

 

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.

Back about ZDDP...

This thread made me wonder about the oil in my motor

For the other people in this thread that may be interested, during my holiday shopping I stopped into a local automotive store (Pepboys) to check out the 1-quart containers of the Mobil-1 specific motorcycle oils. They had both
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.
