It's been in the ground for millions of years but breaks down in an unopened can??? Should there be an expiry date on oil?
Oil does not break down or lose it's lubricating ability. In an engine, it does get contaminated though. Even if the oil is from the 70's, it's still decent oil.

If I had a $60,000 new diesel pick up, I'd use newer oil recommended for the engine. There's thousands of tractors and equipment 40, 50, 60 years old that are still running strong that didn't have any of the newer grade oils in them. According to some, older oil can have better additives than new oil.
