Old 2 stroke oil... was created by !Seymore
Got any 2 stroke experts in the forum? I've asked elsewhere, but getting mixed messages...

I picked these (unopened) oil containers at a GS. Any thoughts on if dino 2-cycle is still good 10+ (maybe 20!) years later?
I know about fuels, but not oils... and this is mostly for watercraft.

It sat in the ground for god knows how many millions of years, don't suppose a few years on the shelf is going to hurt it much.

Engine oil begins to deteriorate the day it's made.  The information I've seen suggests shelf life is 5 to 10 years, but that depends to some degree on how it's stored....temperature, humidity, etc.  I would not use oil that is 20 years old.  It may well be good but why take a chance?
I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.
