Motor oil life unused
While cleaning out my Dad's garage I found some SAE30 Union 76 motor oil. I don't know exactly old, but it is in cardboard cans the have to be opened with one of those spouts that punch through the metal top, and there is an entire case, 24 cans. What is the shelf life of motor oil? Is it useless for an engine? I would never put it in my Crown Vic but maybe an old car that uses a lot? I barely even remember those old spouts and cardboard cans, may be from the 70's or 80's.
