Kitchen cooking oils will not last forever. Depending upon the oil, it can go rancid in a matter of months or a few years. You don't want to cook with rancid oil because it smells like wet socks and the living components have lost their vitality. But the good news is, expired oil won't hurt you. There is no water in it, so no mold can grow to make it rotten and dangerous. It can still be used for creative applications. According to the United States Department of Agriculture Forest Service, “Vegetable oils have many good natural properties including good lubricity, good resistance to shear, a high flash point, and a high viscosity index.” These qualities make them quite versatile in a number of applications. You might consider keeping your old oil rather than throwing it out. Recycling expired oil could prove to be a valuable asset in emergency situations.
