wow thats some expensive oil you have there man!
here in Espania we have the finest extra virgin at 3 euros/ liter which is roughly 4.5 dollars which is roughly 0.5 btc per litre
What you talking about is probably supermarket oil which is handled and preprocessed in commercial stakes which results in lesser quality, if you are near a village in Spain go and ask the villagers their how much their oil is and tell them to tell you the quality of the 3 euro oil, i can also sell Supermarket oil for much less price but that wouldn't be special !
