So I was cleaning out my garage a few weeks ago when I came across a case of older oil. It does have an expiration date but does it really go bad? and if so how old is too old to use?

from what I understand oil breaks down over the course of time. They say that is why you should change your oil every 3,000 miles or 6 months or what ever. Anyway I am not one to talk as I have used "old oil" before what out issues, but not in a newer vehicle.....................

The oil is about 30-40 million years old - so 6 more won't make a difference to it.
However the additives - they may separate out.

sounds good for lawnmowers.

I would put in in my mower but here in vegas our grass is so darn small that I bought a electric mower and it takes me maybe 10 minutes and that is going over it a few times, lol. Oh and yes I had a manual mover too but got tired of the resistance on it. Did a darn good cut job though

and its maybe a little illegal out there the way I use my old oil up as well But then I have a redneck upbringing so mix that old oil with some diesel and gets brush piles burning real good, keeps you warm when you are out there playing in the snow!

So I was really thirsty the other day, and there was not a water fountain in sight, so I broke down and bought a bottle of drinking water. And guess what? It had an expiration date on it. What the hey? Water expires?
On topic, I would go with fresh. I would put it in a beater though, as sealed container oil would probably just have an issue with the additives falling out of suspension as stated above. But you could add an additive...

I only use used oil.

It's not really new oil that I put in when I change my oil, it's just the oil from last time I changed my oil. That way I always have the exact amount.

It's synthetic anyway, right? So it doesn't break down:D

There is virtually no evidence that drinking water beyond the expiration date has any health impact at all. The Food and Drug Administration considers bottled water to have an "indefinite shelf life." Even the bottled-water industry is hard-pressed to justify the labels. The largest U.S., bottled water companies admit the expiration date is more of an optimal taste thing, than a health issue.

For those who have wondered what the difference is in various types of bottled water;

Mineral water: Unlike some waters, this contains a minimum amount of dissolved minerals and other elements. Water is derived from a protected underground source.

Spring water: Retrieved from a natural spring. With the exception of fluoride, no minerals are allowed to be added.

Artesian water: From a well that taps an aquifer, an underground layer of earth that contains water.

Purified water: Water has undergone a process to remove minerals, metals and other substances. The source is usually tap or spring water.

Drinking water: General term means the water is intended for people to drink -- but the term doesn´t tell you anything about where it´s from or how it´s been processed.

Hope this clears things up a bit.

As for the topic, I never use old motor oil. I give it to a friend who burns it in his shop.
