Any oil that is mostly monounsaturated fat is a good choice, because it is easily digested and liquid at room temperature, but stable enough not to go rancid or oxidize. And unlike either saturated or polyunsaturated fat, no one says it’s bad for you! Avocado oil, olive oil & coconut oil are recommended. You should avoid canola oil and other seed oils, even though they are very cheap, as they are lower in monounsaturated fat and very high in inflammatory omega-6 fats which go rancid easily and can cause a variety of health problems!
