There is a general lack of consensus on the smoke points of many popular oils, as well as a lack of standardization for qualifiers such as "refined". Empirical tests are heavily dependent on the qualities of the particular samples (brand, composition, process) available, but appear to be the major source of available data. In the field, experience trumps references, and there is no source that seems truly authoritative. A crude guide is that lighter, more refined oils have higher smoke points. If there is any doubt at all, be fully prepared to extinguish a burning oil fire before heating.
