Over the years I have accumulated multiple sealed containers of oil, synthetic oil, tranny fluid, gear oil, etc. Some of them are in the neighborhood of 10 years old.

How long are these good for? My guess is that they should be good, since they are sealed they should not picking up moisture or any kind of debris, and I don't think they should really degrade.

I am particularly interested in whether or not I can use my gear oil and suregrip additive, which are sealed and probably 7 or 8 years old.

Let me know what you think.

Thanks.
