The term "oil" in turn, refers to a wide range of compounds, most of which are in fact less dense than water, but not all. The narrowest sense is "liquid triglycerides", and all of those that spring to mind do indeed float on water, most definitely including all those that you and I would generally refer to as "vegetable oils". However, chemically speaking, many of the "essential oils" are totally different from plant oils sensu strictu, and some of those "essential oils" are denser than water. Examples include allicin and allyl- and phenyl mustard "oils".
