A different kind of oil question
Does oil, specifically diesel engine oil, go bad over time? I have a chance to get about 10 gallons of unopened diesel oil for free but the date on the containers expired in early 2007 so is it still ok? I don't see what can go bad about it if it's never been open but can anyone out there tell me for sure?

In Trade School they told us that just sitting in the Crankcase and not even running the Engine depletes the addatives in the Oil. But, that was out of the Bottle and 1975 technology.
However, I bet the Military/Government is using Oil stored for much longer periods. I think that if you Change your Oil every 3,000 miles are so I doubt if there would be any problem. If it is also a brand that you can buy you could mix 1/2 new with 1/2 old.

I'm sure it would be dangerous for you to use that oil. I will dispose of it for free for you by putting it in my diesel. I am near you in Sonoma County and will come get it, just let me know.

I am surprised it has an expiration date...
In a sealed container it is not taking in any condensation ...which is a major contaminate on a non used engine. I would use it and not worry about it. That was very nice of Jeremy to offer to dispose of it for you...

Due to the latest specs being changed for emissions reasons, it's probably better than what you would buy off the shelf today.

You can use the same copper washer a bunch of times. I don't bother replacing one until I see something visibly wrong with it.

Old trick for solid copper washers (NOT the composite crush type) commonly used for oil seal, if they are in good shape, not scored or over tightened to distortion: Put it on a flat surface solid enough to take heat without warping, put it in the oven (when other half not watching), set for 150 to 200 degrees (F), when the oven comes up to temp, turn it off a let it cool, and reuse.
It works, but is usually reserved for weekends after the parts place has closed, or the sizes you just can't find.

Yeah, if you believe carbon dating is accurate.

I have been told that carbon dating is only accurate to about 10000 years. Because thats the half-life of carbon. Anything past that is speculation.

Well then if the carbon dating on the oil is off by that much then it's 60,010,000 so the extra 10,000 might make a difference
I just thought some additive in the oil might have a shelf life.

For anything older than 100,000 years they use either Strontium or Thorium for dating.
