Flavoring extracts won't change that all these different oils have different smoke points and different ratios of fats.

e.g Walnut oil can be used a salad dressing , heating it is bad.

Olive oil has a lower smoke point than cheaper oils so faking olive oil has been pretty easy.. I don't actually buy Italian olive oil since anyone who is faking oil internationally would be pretty crazy to make less by selling it as Spanish or Greek olive oil.
