I personally did a deep dive into oils from a technical standpoint for soap making. An oil when made into soap is bad when the soap turns yellow. Still mostly fine as soap but soap does not extend the lifetime of the oil its made of. At first all my soap was changing yellow very shortly after making it. Turns out grocery stores are a terrible place to buy most oils, including olive oil.

tl;dr high saturated fat oils and castor oil are peak for cooking with.
