I use canola as well as my basic cooking oil. It has the most favorable Omega 3 to Omega 6 ratio of the less expensive oils, and has a neutral flavor and reasonably high smoke point. It is only slightly lower in monounsaturated fats than olive oil.
Grapeseed oil has a higher smoke point, so I use it when I am searing at a very high temp. However, it does not have a good Omega 3:6 ratio, and does not have the monounsaturated fats that Olive Oil and Canola oil have.
Probably the very BEST cooking oil is Macadamia Nut Oil, but it is pretty expensive. It is 83% MUFA and has a 1:1 Omega 3:6 ratio and a higher smoke point than grapeseed oil. nutritiondiva.quickanddirtytips.com/is-gra
