Interesting, all of the different responses here.

For me it is mainly extra virgin olive oil for everything that does not require high heat. I was lucky to find this one a few months ago.
It is absolutely amazing and by far the best olive oil I have ever tasted. No worries that it would be fake, you can taste it immediately. In generally I grew the taste for south Italian EVOO and don't really like the bitter varieties you get from elsewhere.
For anything high heat I always use refined sunflower oil.
In my country it is also very common to use cold pressed pumpkin oil to season salads. Not much other use for this oil except to put a bit into pumpkin soup when you serve it or spice an ice cream with it. This year I also got a few bottles of unrefined sunflower oil. After reading this thread I was checking smoking point of oils and I see this one has only 107C so no use for cooking. But is sure smells amazing, totally different oil than its refined variety.
