Canola Oil
Canola oil is also a recommended substitute. However, similar to olive oil, the proportion of substitution is the key, which varies from one recipe to another. It also depends on the cooking procedure that you are opting for. For example, if you are substituting it in baking, then you need to use 10 tablespoons per cup of butter. On the other hand, if you are using it while cooking on a flame, then you need to use 14 tablespoons per cup of butter.
