I don't know.I was cleaning out a basement and ran across unopened cans from probably the '40s. I threw them out only because oil was pretty basic stuff back then,without some of the modern additives etc.But the basic oil has been in the ground for what,hundreds of millions of years? Seems like 3 more isn't going to spoil it.However,if it was me I still think I'd put it in the lawn mower first.
