I think I am going to try the Kirkland organic oil. They did a test on it some years back and it was the only imported oil that meet extra virgin standards. I don’t know how much oleocanthal it has in it, but it comes from Italy where oleocanthal content is known to be high. California oil was generally low in content according to that paper I linked up thread. Seagate sounds good, but there is no external scrutiny that I could find.

Seagate’s oil is new to market, but all of their other products are top notch. I may try the Kirkland as well.
