Whether or not it's food grade is going to be the biggest issue here. Personally I would not want to use an oil that's not specifically labelled as food grade, or that the manufacturer cannot provide documentation that it is food grade for. I've also had e oil turn, so I'm not sure about that in the long term. The little bottle of cutting board oil I have (food grade mineral) is lasting forever because my boards only need a few drops at a time.
