I'd be curious to hear what Molakule or SonOfJoe had to say about this, but I'd imagine this would be fine in an older vehicle as long as nothing in the oil has deteriorated over time.
Not thinking of the oil itself but the additives...seems like something robust enough to survive in a hot engine for 6 months or whatever should be stable on a shelf for 12 years, but I am out of my depth on this stuff.
Didn't somebody here contact XOM and was told that 5 years was a safe shelf life for M1? That would surely be a well padded figure, also....
