50% VG is the highest TV will go.
TV will always use the maximum amount that WE CAN given the ingredients. AGAIN: Any liquid that uses an essential oil as a flavoring ingredient will have a difficult time incorporating with high quantities of VG. We can help this by the use of a blender's alcohol, but in this circumstance, anything beyond 30% VG, you WILL, I repeat WILL experience separation of the ingredients.
So, liquids that use Almond, Orange, Lime, Clove, Anise, Cinnamon, as these are all essential oils, the maximum amount of VG that is allowable is 30%.
The second thing for consideration is nicotine level. If you want a 48mg or 36mg liquid, 30% VG isn't possible, due to (bottle) space constraints. The more nicotine base we need to use for that bottle of liquid, the less room in the end that we have to add VG.
