Thanks all. For those following, I did ask VZ flat out if their concentrated flavors contained oil. The response I got to that was "They are alcohol base. I would think that 30% distilled water is too much and is thinning your juice out too much. VG takes longer for the flavoring the blend well. I use a 10% distilled water mix with my VG juice and it is plenty enough to thin out and work well with my clearomizers, cartomizers, atomizers."
