I copied the info below from Dr Mercola's site. Most have probably read it already but I thought that the advice was worth passing on.
OLIVE OIL
As it turns out, extra-virgin olive oil contains chlorophyll that accelerates decomposition and makes the oil go rancid rather quickly.
In fact, Dr. Moerck actually prefers using almost tasteless, semi-refined olive oil rather than extra-virgin olive oil for this reason.
If you're like most people, you're probably leaving your bottle of olive oil right on the counter, opening and closing it multiple times a week. Remember, any time the oil is exposed to air and/or light, it oxidizes, and as it turns out, the chlorophyll in extra virgin olive oil accelerates the oxidation of the unsaturated fats.
Clearly, consuming spoiled oil (of any kind) will likely do more harm than good.
To protect the oil, Dr. Moerck recommends treating it with the same care as you would other sensitive omega-3 oils:
Keep in a cool, dark place
Purchase smaller bottles rather than larger to ensure freshness
Immediately replace the cap after each pour
To help protect extra virgin olive oil from oxidation, Dr. Moerck suggests putting one drop of astaxanthin into the bottle. You can purchase astaxanthin, which is an extremely potent antioxidant, in soft gel capsules. Just prick it with a pin and squeeze the capsule into the oil.
The beautiful thing about using astaxanthin instead of another antioxidant such as vitamin E, is that it is naturally red, whereas vitamin E is colorless, so you can tell the oil still has astaxanthin in it by its color.
As the olive oil starts to pale in color, you know it's time to throw it away.
You can also use one drop of lutein in your olive oil. Lutein imparts an orange color and will also protect against oxidation. Again, once the orange color fades, your oil is no longer protected against rancidity and should be tossed.
This method is yet another reason for buying SMALL bottles. If you have a large bottle, you may be tempted to keep it even though it has begun to oxidize.
