Oils all have a tendency to turn into a crisco-like consistency, it's just a matter of what temperature they do it at. I've never had Olive oil go bad, so I can't say I've been inclined to try refrigerating it, but I have seen booties of it left in someone else's basement where it got very cold in the winter. It looked like you could scoop it. Definitely a no-go on pouring it.
