That only applies to real olive oil, I wouldn't trust industrial mixed vegetables processed oils.
To the contrary, I discovered quite by accident that "industrial mixed vegetables processed oils" will last virtually forever. When we were preparing to move from the city to where we live now, we discovered a moving box, from a previous move 10 years prior, at the back of a closet. Inside was a bottle of canola (rape seed) oil. To my surprise, the oil was not rancid.
This might seem like a good thing but it's not. When I investigated how this could be possible, I found out that part of the "processing" of these oils is to let the oil go rancid, clean it with detergents and then bottle it for sale. It cannot go rancid because it is rancid already!
Needless to say, I only cook with cold-pressed vegetable oils now. It is not healthy for us to consume rancid oils.

P.S. All commercial canola oil, at least in Canada, is GMO.
