**PS i know nothing,so please chime in if you have knowledge on this topic
This was originally written in this post about separating juice. I have a B.S. in chemistry; the chemicals that impart flavor are often terpenes, esters, and alcohols, which are not oils, oils are lipids. Terpenes, esters, and alcohols can have oil-like consistencies, but they are not oils/lipids, and hence cannot cause lipid pneumonia. These chemicals are soluble in lipids and to varying degrees in vg. Since volatile organic compounds which impart flavor are not always fully soluble in vg due to vg being hygroscopic and "water-like", they may separate over time. If someone was using any true oils, i.e. lipids, the lipids would have to be emulsified into the vg/pg, which would create a semi-opaque liquid similar to runny mayo. The vendor has stated he uses citrus extracts, citrus extracts, citrus essential "oils" do not consist of lipids, lipids do not impart aroma.

As you can see, http://en.wikipedia.org/wiki/Octyl_acetate is an ester which imparts the flavor of oranges; it has a very long hydrocarbon chain on it, this makes it almost insoluble in water-like compounds like vg, and it would separate into an oily (but not lipid) and watery phase.
TL;DR: essential oils don't consist of lipids, and citrus flavors separate because of the chemicals that taste like citrus, and not because vendors are using lipid-oils in their juice and trying to give people lipid pneumonia.
