I think supermarket oil is fine. The fake oil is mostly sold in discount shops like tk maxx and home bargains

How do you know?

I mean, this might down vote me even further. But I am from Spain. I can taste it. I use olive oil on pretty much everything. I never ever use any oil other than extra virgin olive oil. Even for frying

In fact, I can tell you that the 5 * oil sold in luxury bottles abroad is no better than the plain extra virgin. And that is where the fraud mostly exists (besides mixed oil in tk maxx). I have never been able to buy luxury oil outside of Spain. All the luxury bottles abroad contain normal oil. But I don't really care for luxury oil anyway. Normal extra virgin fulfills all my health and taste requirements

At the end of the day, if this misunderstood awareness of "fake oil" benefits my fellow countrymen and helps them develop supply chains of verified, expensive higher grade oils (which are a waste of money in my view but nevermind) then I guess these campaigns are very good. People in Spain extremely rarely will use anything other than plain extra virgin. It's like eating caviar. And farmers really struggle to get a fair price, especially when selling bulk to foreign buyers

No, there are widespread problems with olive oil fraud.

Plenty of studies have been done by purchasing a large # of bottles from supermarkets and they've all shown half or more of olive oils are either fake or rancid.
