I've been using the same can of 3-in-1 oil for at least 30 years. And it wasn't a new can when I acquired it - it has "1968" on the side.
Some time back I ran out of military-surplus gun oil and tried the 3-in-1, liked it better, and kept using it. I finally ran out, and my wife brought home a new plastic bottle from the Wall-Mall. I carefully pried the applicator off the old metal fan and refilled it from the new bottle.
Oddly, the 45-year-old oil had a very strong odor; the new stuff has only a very slight odor. 3-in-1 used a lot more citronella back in the old days, particularly for it to be that pungent after 45 years...

1. All guns are always loaded.
2. Never let the muzzle cover anything you are not willing to destroy.
3. Keep your finger off the trigger until your sights are on the target.
4. Be sure of your target and what is beyond it.
I guess I must have been in a coma for 4 or 5 decades, but I did not know 3 in 1 oil was still available! I grew up with a can of 3 in 1 that we used for everything around the house. I'm going out and buy some today; thanks for the tip OP!!!
I used 3-in-1 oil for years before I started using Frogube and Fireclean, more as an experiment rather than finding a better product. 3-in-1 oil is not a great rust preventitive compared to other gun products but is a fine lube.

When I was still a kid, I started using 3-In-1 oil for lubing my guns after I had filched all the Singer Sewing Machine oil out of my mother's sewing machine cabinet. I can still smell that strong 3-In-1 odor in my mind which reminds me of fooling with my guns in my bedroom at home.
Actually, I didn't much care for the odor. It did lube well though. I like light oils.

I still use 3 in 1 oil on my firearms as well as sewing machine oil. Its inexpensive, no fancy super duper do everything blather, and it works. Soaks into my parked 1911's and stays there. It works as designed, its a lubricant, not a bore cleaner.
I use it too. Works fine for weekly/monthly lube jobs. I wouldn't recommend for long term (use Vaseline for that).
Use it for resizing rifle brass too. Wipe on, wipe off, resize.
Best thing about it, clings to bare metal really well!
I tend to use isopropyl alcohol as a final cleaner/degreaser, then lube.
I don't carry to deter crime. I carry to defend myself!
Once I figured out that WD40 was not worthwhile as a lubricant (about 30 years ago) 3-In-1 has always had a place on my workbench.

Considering the length of time it takes to turn dinosaur poop and leafs into oil 30 to 50 years doesn't sound like a long time.
The can will probably dissolve before the oil is no longer good.
Oops, I forgot they changed to plastic bottles now for 3in1 so the bottles will last half the life of the oil.

Pretty sure 3 in 1 is mostly 30 weight auto motor oil, but can not remember the brand at this time. I have been pleased with Aeroshell 50 weight drippings out of the airplane oil changes.
I have always loved the way 3 in 1 oil smelled as far back as when I was about eight years old. I used to use it on my locomotives.
I like all kinds of foreign guns.

I'm old but not old fashioned, I use Mobil1 for lube.
Like the OP, I've got an old can of 3 in 1 I still use occasionally. Not very often, as it does stink to high heaven. Never used it on my weapons, but would if that's all I had.
Never argue with an idiot in public. People passing by won't know which one of you is the idiot.
