[edit] seed oils r bad skeptics can just double check - the top 3 highest smoke point oils are all fruit oils, with seed oils at a distance - with the exception of peanut oil, which is closer.
The smoke point is also not the only relevant factor, the fatty acid makeup is also important, high omega-6 oils are more likely to oxidize, coconut oil for instance is high in saturated fat, olive oil is mainly monounsaturated.
