Olive Oils; Which blends are best

I use several Olive oils for my cooking. A light olive oil for frying meats & fish, Fairway Extra virgin for sauting vegetables, Greek olive oil called Kalamata extra virgin for adding to recipes and Fairway Organic Olive oil Puglia Italy, extra virgin Pugliese un-filtered, grassy artichokey for dipping bread and toast.
I own a Foodsaver vacumm sealer and it comes with bottle stoppers that you can vacumm the air out of the bottles for storing. Is it needed to vacumm the air out of the Olive oil bottle to keep better or does it not matter? I heard light breaks down Olive oil but if this was true then why sell it in clear bottles not tinted like beer. I like using Fairway Organic Olive oil instead on butter on bagles with some bread dipping spices that comes 4 different blends to a jar. :chef:

the light and extra virgin are used every day but the other 2, greek & organic aren't used as much and do sit in the closet for a few months. I must say i like the organic olive oil on a bagle more than butter with a little dipping spice. :chef:

Kirkland Olive oil

Today i was in Costco and bought a bottle of Kirkland Extra Virgin Olive oil Toscano from Tuscany (haevest 2004 maximum acidity %5 :confused: ) THis is the first i have seen that comes in a dark green tint bottle for what reason? Do you think it's just cause the bottle looks better or is it to keep light from the oil. No other Olive oil except for Carpillia top stuff comes in a dark tint bottle. :chef:
