From my experience:
You can fit about 15 drops of oil in a "0" capsule. You may combine several different oils into one capsule. I have never bothered to dilute with olive oil, but if your stomach is sensitive, this is advisable. I rarely ever "fill" the capsule, having found that less is many times just as effective and more.
Start slowly and see how your system tolerates ingesting the oils. Remember, you do not have to fill the capsule up before you swallow it.
The reason for using vegetarian caps is that they take a lot longer to break down. If I fill them carefully and don't have oil on the outside, I have seen them last for several weeks in a dark jar.
