Thanks for the help. I tried rubbing it between my fingers (inconclusive, didn't feel like mineral oil or motor oil), tried tasting it (inconclusive, couldn't taste oil but then tongue was hot and tingly from Cinnamon flavor), tried burning on toothpick (toothpick caught fire immediately but it also did the same thing with the control toothpicks [one bare and one with mineral oil]). Wife (who is not as convinced of the safety of vaping as I am) had a lot to say about the last test. Guess I will have to wait for a reply from Bear Juice on if it is oil or not. I can shake it really well and it will separate out fully in about 20 minutes.
