Very old Castrol gear oil...

Look at the bottom of your container.

If you see some discoloration or particles then one or more of the additives may have "dropped out".

 
He said it was "unopened." What could have happened to it?
Stuff has a shelf life, probably including oil. 15 years worth of unopened day/night, winter/summer, hi/lo humidity, whatever. Sitting in a plastic container (we all know they contaminate whatever is in them, right?). Hey if it floats your boat, have at it. What if you found a 12 pack of 15 year old condoms? Unopened condoms. What could have happened to them? Like I said, call me crazy, but I'm not using the old stuff unless I have an engineer sight off that it's ok. For the sake of 13$?
Haha...Using 15 year old Condoms is asking for 18 years of problems. That is apples and oranges, but you may be right. For the cost of a new bottle, is it really an issue? Hell, I don't know. Just don't use old oil on your new condoms.

 
Well I toasted my final drive on my (since crashed and replaced) 2014.
However, that was because I didn't torque the drain plug, and she **** the oil out 100-ish miles from home.

Nothing like a whale **** thread to break up the week....
Sorry Pants but self induced **** ups don't count against Yamaha final drives.

 
Like mikerider, I'd want to use it to keep from wasting it, but I wouldn't.

What could go wrong with it? I don't know. But I also don't know that after 15 years it'd still be as good as I want for a bike I'm hoping will last me several more years. The fact that I don't know would make me uncertain enough that I wouldn't want to use it for the next several years -- he did say he had several bottles.

Yes, the base product came out of the ground and had been there millions of years, but that crude isn't what we're using. It has to be refined and blended somewhere with additives that I'm not sure are good for 15 years. Maybe they are; maybe they aren't.

is it fine? Probably. But the oil I'm currently using is under $10 a quart -- about $2 a change. For that price, I'd want a little more certainty than "probably" before using it for the next several years.

 
If I had a dollar for every one of my self-induced screw ups, I could afford to put whale **** in every motor I own for the rest of eternity!

I didn't realize that oil does have a shelf life. Thanks. It's all those additives that expire, I see.

It was a full size Bronco that I kept for 13 years that's now long gone :)

Uh, I think this is wrong. I'm still dealing with this after 20 years and it looks like a few more still to go.

18? That would be just awesome!
