What is a low smoke point vs. a high smoke point, for cooking oils?

You mention on your website that that you should use lower temps to cook with olive oil and grapeseed oil for higher temps. Where do you draw the line for temperatures?

Dr. Gourmet Says...

olive oil being poured over black olives

"Smoke point" is the point at which, when heated, an oil will begin to smoke. One of the main factors is how many impurities there are in a particular oil. While the oil itself will burn, it is often the impurities that will burn before the oil.

Below is a list of different smoke points that I have collected over the years from a variety of sources. Hope this helps.
