Bottom line:
Nobody knows and a few like to make jokes. But the semi synthetic oil has dates on the bottles which imply at least an expiration date. I would think that the adults on this Blog would be interested in finding out what that is and why it is.

Only half of this oil was in the ground for a million years as one wise guy observed. The other half was distilled/manufactured by Shell. With our engines at risk I think we should find out if these dates mean anything to us. If they don't then we should discover why they are on the bottles.

I intend to do that.

This thread reminded me (my age is showing) I had a case of Aeroshell left over from the 70's. Oil "can" was actually paper back then. I was cleaning out the garage last summer and found the case of old oil like an archeology dig. Every "can" was leaking at the spiral wind and some cans were half empty. I gave the case of oil to a guy and he used it in his Cub...

One of the reasons that oil manufactures loosely talk about an expiration date is the additives. The additives in the oil can and will settle out. Oil that has been sitting for a couple of years will need to be shaken thoroughly to evenly disperse them in the solution.

Default and from the 'somebody always has to top it dept',

I've got a couple of cans (likely from my dad's collection, or my teen years) of Havoline and a can of Quaker State that are literal cans; as in steel cans, rusting on the outside. I'd post pics, but... well, you know.

Unopened. Make me an offer I can't refuse.

I asked the AeroShell Rep at AirVenture Oshkosh a few years ago about the Expiration Date on a case of AeroShell 15W-50 that I had sitting in my hangar. He was adamant that it was NO GOOD after the expiration date.

Not sure if it was the additive package in the oil or what. There is a link above that was posted to an AeroShell retest date so not sure how us end users go about retesting once the product we have is past its shelf life date.

My wife says the $50 bill in my wallet is going to expire soon and I should buy a nice dress for her that's on sale at Macy's...

Aeroshell Sport Plus 4 oil was reformulated a bit about a year or two ago. At that time, Aeroshell/ROTAX said that older remaining stock could be used until the newly-reformulated oil was available. As to an absolute age limit, I do not know.
