Does oil get old?

[fwi]

Found a gallon of Kawa Chem Jetski High Performance oil that has been sitting in the basement for over a year. It has a faint ammonia smell, is this a normal odor. Is this a synthetic oil and can it "get old"?
I normally use Penzoil outboard 2 cycle tcw-3, which is much more of a blue color, no ammonia smell, and this one is almost black.

I don't think so its 10 billion years old already another year here or there sure won't hurt a thing.

Sounds like used motor oil.

I'd guess used motor oil as well.

Read the bottle. What color is the oil suppose to be?

I think it's a synthetic blend.

I remember the Kawi oil having the strong ammonia smell. I would say that it is ok to use. Prolly just the detergent additives making it smell.

Pour some into a clear container, you should know pretty quick if its used.

I ran across a quart bottle of 2 stroke oil that has been sitting on a shelf for about 2 years with the lid off. I went to use it but part of the oil has coagulated together. So I only use it in the weedeater and stuff.

I just poured some into a clear glass, it's definitely not used oil. It is clear and has sort of a purple color to it.

It should not go bad for a very long time if ever .

Thank you all.

kawa chem is purple. You should be fine. I just used some that is over 5 years old with no problems.
